Comparison between Suture-Button Technique with Syndesmotic Repair and Screw Fixation Technique for Complete Ankle Syndesmotic Injury: Biomechanical Cadaveric Study. Clin Orthop Surg 2025; 17:324-330.

Abstract
Background The tibiofibular syndesmosis is essential for preserving the stability of the ankle. Acute syndesmotic injuries with evident or latent instability usually warrant surgical interventions. This cadaveric study examines and compares biomechanical characteristics between the following treatments for syndesmosis injuries: suture-button fixation plus syndesmotic repair and screw fixation. Methods The lower extremities of 10 cadavers disarticulated at the knee joints were used, yielding 20 feet. Ten feet underwent surgery using the suture-button fixation with syndesmotic repair, while the remaining 10 feet underwent surgery using screw fixation. Before surgical treatment of syndesmosis injuries, each cadaveric lower limb underwent preliminary physiological cyclic loading, which was followed by a series of postfixation cyclic loading tests after the surgical procedure. Results Our principal finding is that suture-button fixation with syndesmotic repair provided torsional strength comparable to that of screw fixation. The mean failure torque did not differ between the 2 groups, but the rotational stiffness was significantly lower in the suture-button fixation/augmentation group. Conclusions Suture-button fixation/augmentation facilitates flexible (physiological) syndesmosis movement and may be a useful alternative treatment for ankle syndesmosis injury.

Abstract
Syndesmotic instability or malreduction is an independent risk factor for an impaired patient-rated outcome. If a syndesmotic injury is suspected, a stepwise diagnostic approach including plane radiographs, MRI, and bilateral stress radiographs should be conducted to differentiate stable from latent unstable and frank diastasis cases. The basic requirement for any surgical treatment approach is a stable and anatomically reduced distal tibio-fibula joint. The best treatment approach for a 2-ligament injury (anterior inferior tibio-fibular ligament [AiTFL] + interosseous ligament [IOL]) seems to be the suture-button system, for a 3-ligament injury (AiTFL + IOL + posterior inferior tibio-fibular ligament), 2 fixation devices.

Abstract
BACKGROUND Syndesmotic ankle fractures occur when damage to the syndesmosis complex is combined with a malleolar fracture. This can result in severe pain, weakness, and instability. Surgical interventions include syndesmotic screw fixation (SS), suture button fixation (SB), and tibiotalocalcaneal nail (TTC). This meta-analysis aims to compare the outcomes of these treatment methods for syndesmotic ankle fractures. METHODS A literature search was conducted on PubMed and Embase for comparison studies that included at least 2 surgical interventions and at least one of the relevant functional outcomes and/or complication metrics until June 2024. The Olerud-Molander Ankle Score (OMAS) was used to compare functional outcomes, and it is a self-reported outcome measure that evaluates the symptoms and function of those with ankle fractures, while infections and reoperations were reported to compare complication outcomes. Statistical analyses were performed using Review Manager 5.4. A P-value ≤ .05 was considered statistically significant. The risk of bias was assessed with Review Manager 5.4. and the Newcastle-Ottawa scale. RESULTS A total of 18 studies with a total of 1,040 patients were ultimately included in this study. The SS had a significantly higher OMAS 2-year follow-up compared to TTC. The TTC had a significantly lower infection rate compared to SS. The SB had a significantly higher OMAS at both 1-year and 2-year follow-ups than SS. The SB had a significantly lower reoperation rate compared to SS. The SB had a significantly higher OMAS at both 1-year and 2-year follow-ups than TTC. The SB had a significantly lower infection rate compared to TTC. CONCLUSION The SB emerges as the preferred treatment method for syndesmotic ankle fractures, while TTC stands as a viable alternative. The SB is recommended as the primary surgical intervention for patients with syndesmotic ankle fractures due to its superior clinical benefits when compared to TTC and SS. LEVELS OF EVIDENCE 3.

Abstract
Background Syndesmotic instability is a significant concern in the management of unstable ankle fractures, occurring in approximately 10% to 13% of these cases. Early recognition and stabilization of syndesmotic injuries are essential to ensure optimal long-term outcomes. Several techniques are currently in use, often involving complex procedure and/or costly devices. Our study presents a syndesmosis fixation technique using K-wires that is both simple and cost-effective. Methods This is a retrospective single-center case series. Three hundred seventy-seven ankle fractures with intraoperative syndesmosis instability and subsequent syndesmosis fixation with a K-wire were treated between 2002 and 2012. Of the 377 patients, 51 died and we were able to obtain long-term questionnaire completions from 94 patients (29% of presumed living patients), with a mean follow-up of 10.6 ± 3.0 years. Results The mean age was 46.6 ± 18.5 years; 42% were Danis-Weber type B and 58% type C fractures. Syndesmosis fixation failure was observed in 9 (2%) patients, and 5 (1%) patients had K-wire displacement without loss of syndesmosis reduction. The Manchester-Oxford Foot Questionnaire (MOXFQ) was obtained 10±3 years after surgery. The mean MOXFQ pain score was 25.9 ± 25.4, the mean functional score was 18 ± 24.8, and the mean social score was 13.7 ± 22.2. Conclusion We report long-term (10.6 ± 3 years) functional outcomes using a validated patient-reported questionnaire in patients who underwent syndesmosis fixation with 2 K-wires for unstable ankle fractures. In the subset of patients we were able to find in follow-up, we found low rates of syndesmosis fixation failure, low pain scores, and excellent functional outcomes. The availability and low cost of these implants make this technique an accessible and cost-effective solution to consider for syndesmosis fixation.

Abstract
BACKGROUND Clamping along the transsyndesmotic (TS) axis decreases the risk of malreduction when reducing syndesmotic diastasis. We aimed to measure the difference between the TS axis and the axis determined by the newly proposed fluoroscopic incisura tangent (IT) method. The measurements were compared to those between the TS axis and those based on the center-center (CC) and talar dome lateral (TL) methods. METHODS We analyzed computed tomographic images of 43 normal ankles. The IT view was simulated using a digitally reconstructed radiograph, in which the anterior and posterior fibular incisura tubercles overlapped on the internally rotated anteroposterior view. The interaxis angle between the TS and the axes determined by the IT method was measured on the axial computed tomographic image corresponding to the radiographic image. The same procedure was repeated using the CC and TL methods. The measured values were compared between the three methods using a one-factor analysis of variance. Furthermore, the measurements of the anteverted and retroverted incisurae were compared for each fluoroscopic method. RESULTS The mean interaxis angles between the TS were - 0.5 degrees, 6.3 degrees, and - 1.8 degrees for the IT, CC, and TL methods, respectively, with a significantly larger value for the CC method than for the IT and TL methods (P < .001). No significant difference was found in the interaxis angle in the anteverted (-0.1 degrees) and retroverted (-1.0 degrees) incisurae when using the IT method (P = .15). The angles in the retroverted incisurae were larger than those of the anteverted incisurae for the CC and TL methods. CONCLUSION The fluoroscopic IT method accurately estimated the TS axis. The interaxis angles were consistent, regardless of the incisura anatomy. The fluoroscopic method can be used to clamp and fix the syndesmosis along the TS axis. LEVEL OF EVIDENCE Ⅳ.

Abstract
BACKGROUND Management of syndesmotic injuries with screw fixation has potential disadvantages, which may lead to the loss of some of the ankle functions. The use of the suture-button system instead can overcome these disadvantages. PATIENTS AND METHODS In a prospective study, 32 patients with acute isolated syndesmotic injuries were treated with a suture-button device. Follow-up was for a minimum of 2 years, regarding the Visual Analogue Scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) score, patient satisfaction at 3, 12, and 24 months, and radiological assessment. RESULT A significant improvement regarding pain (VAS during rest 5.6 and during walking 6.1 preoperative improved to 0.1 and 0.2 postoperatively, respectively. (P values were < 0.0001 for both pain during rest and walking) and AOFAS score (improved significantly from 44 ± 7.5 pre- to 99 ± 8.7 points postoperatively (P value was 0.0034). The improved VAS and AOFAS scores of the repaired ankles gradually reached the values of the contralateral uninjured ankle (evaluated at 3,12, and 24 months, postoperatively). Radiographs and CT of both ankles - repaired and healthy ankles - were similar at the 3 months follow-up. Early full weight-bearing and early return to work and sport characterized all patients. There was no need for hardware removal. CONCLUSION Suture-button treatment for acute isolated ankle syndesmotic injuries leads to favorable clinical and radiological outcomes. Postoperative radiographs and CT denoted maintained ankle stability. Patients can do early full weight-bearing and early return to work and sport.

Abstract
Background Syndesmotic injuries are frequently stabilized using syndesmotic screws. Traditionally, these screws were routinely removed during the postoperative period, however recent literature has brought into question the necessity of routine removal, citing no change in functional outcomes and the inherent risks of a second surgery. Our study aimed to compare outcomes of patients undergoing routine syndesmotic screw removal versus those undergoing an on-demand approach to removal. Methods A systematic search of studies comparing routine syndesmotic screw removal to on-demand screw removal following an acute ankle fracture, or an isolated syndesmotic injury was conducted across seven databases. Only Prospective randomized controlled trials were eligible for inclusion. Data reported on by at least 2 studies was pooled for analysis. Results Three studies were identified that met inclusion and exclusion criteria. No significant difference in Olerud-Molander Ankle Score (MD -2.36, 95% CI -6.50 to 1.78, p = 0.26), American Orthopedic Foot and Ankle Hindfoot Score (MD -0.45, 95% CI -1.59 to .69, p = 0.44), or dorsiflexion (MD 2.20, 95% CI -0.50 to 4.89, p = 0.11) was found between the routine removal group and on-demand removal group at 1-year postoperatively. Routine removal was associated with a significantly higher rate of complications than on-demand removal (RR 3.02, 95% CI 1.64 to 5.54, p = 0.0004). None of the included studies found significant differences in pain scores or range of motion by 1-year postoperatively. Conclusion Given the increased risk of complications with routine syndesmotic screw removal and the comparable outcomes when screws are retained, an as-needed approach to syndesmotic screw removal should be considered.

Abstract
INTRODUCTION The present meta-analysis evaluated current level I clinical trials which compared the use of a suture button (SB) versus syndesmotic screw (SS) fixation techniques for syndesmosis injuries of the ankle. The outcomes of interest were to compare patient-reported outcome measures (PROMs) and complications. It was hypothesised that SB might achieve better PROMs along with a lower rate of complications. METHODS This study was conducted according to the 2020 PRISMA statement. In August 2023, PubMed, Web of Science, Google Scholar, and Embase were accessed. All the randomised controlled trials (RCTs) which compared SB versus SS fixation for syndesmosis injuries of the ankle were accessed. Data concerning the American Orthopaedic Foot & Ankle Society (AOFAS), and Olerud-Molander score (OMS) were collected at baseline and at last follow-up. Data on implant failure, implant removal, and joint malreduction were also retrieved. RESULTS Data from seven RCTs (490 patients) were collected. 33% (161 of 490) were women. The mean length of the follow-up was 30.8 ± 27.4 months. The mean age of the patients was 41.1 ± 4.1 years. Between the two groups (SB and SS), comparability was found in the mean age, and men:women ratio. The SS group evidenced lower OMS (P = 0.0006) and lower AOFAS (P = 0.03). The SS group evidenced a greater rate of implant failure (P = 0.0003), implant removal (P = 0.0005), and malreduction (P = 0.04). CONCLUSION Suture button fixation might perform better than the syndesmotic screw fixation in syndesmotic injuries of the ankle.

Abstract
INTRODUCTION The literature largely addresses questions of diagnostic accuracy and therapeutic accuracy. However, the magnitude of the clinical impact of syndesmosis injury is commonly described in intuitive yet qualitative terms. This systematic review aimed to quantify the impact of syndesmosis injury. METHODS Published clinical outcomes data were used to compute an effect size reflecting the impact of syndesmosis injury. This was done within the clinical contexts of isolated syndesmosis injury and syndesmosis injury with concomitant ankle fracture. Clinical outcomes data included Olerud-Molander (OM) and American Orthopaedic Foot and Ankle Society (AOFAS) scores, visual analog scale for pain, and days missed from sport competition. Parametric data were compared with Student t tests. Effect size was computed using Cohen's d. RESULTS In ankle fracture patients, syndesmosis injury demonstrated a large effect size for OM (d = 0.96) and AOFAS (d = 0.83) scores. In athletic populations without concomitant ankle fracture, syndesmosis injury demonstrated a large effect size on days missed from competition (d = 2.32). DISCUSSION These findings confirm the magnitude of the negative impact of syndesmosis injury in athletic populations with isolated injury and in ankle fracture patients. In ankle fracture patients, this large negative effect remains despite surgery. Thus, syndesmosis repair may not fully mitigate the impact of the injury.

Purpose Ankle injuries involving the tibiofibular syndesmosis often necessitate operative fixation to restore stability to the ankle. Recent literature in the adult population has suggested that suture button fixation may be superior to screw fixation. There is little evidence as to which construct is preferable in the pediatric and adolescent population. This study investigates outcomes of suture button and screw fixation in adolescent ankle syndesmotic injuries. Methods A retrospective matched cohort study over 10 years of pediatric patients who underwent ankle syndesmotic fixation at a large Level 1 Trauma Center was conducted. Both isolated syndesmotic injuries and ankle fractures with syndesmotic disruption were included. Preoperative variables collected include basic patient demographics, body mass index, and fracture type. Suture button and screw cohorts were matched based on age, race, sex, and open fracture utilizing propensity scores. Outcomes assessed include reoperation and implant failure. Results A total of 44 cases of operative fixation of the ankle syndesmosis were identified with a mean age of 16 years. After matching cohorts based on age, sex, race, and open fracture status, there were 17 patients in the suture button and screw cohorts, respectively. Patients undergoing screw fixation had a six times greater risk of reoperation (p = 0.043) and 13 times greater risk of implant failure (p < 0.001). Out of six cases of reoperation in the screw cohort, five were unplanned. Conclusion Our findings favor suture button fixation in operative management of adolescent tibiofibular syndesmotic injuries. Compared with screws, suture buttons are associated with lower risk of both reoperation and implant failure. Level of evidence level III therapeutic.

Abstract
BACKGROUND To retrospectively evaluate the clinical outcomes of patients treated for syndesmotic injuries with an all-suture construct technique and compare their patient reported outcome scores with historically published outcomes of syndesmotic injuries fixed with suspensory suture buttons. METHODS This was a retrospective case series of patients treated at a Level 1 Trauma Center from May 1, 2018, to June 30, 2022. Ten patients aged 18 and older with unstable syndesmotic injuries treated with all-suture repair. Patients were excluded if they were treated with trans-osseous screws, had previous failed syndesmotic fixation, or suspensory suture button fixation. Patient-reported outcomes including Visual Analog Scale (VAS) pain scores, American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot scores, and complications were recorded. RESULTS In the patients with 6 weeks or more of radiographic follow-up (N = 9), there was no evidence of nonunion, loss of fixation, hardware complication, or whitling of the fibula by the suture. At final follow-up average VAS pain scores were 1.5 out of 10 (range 0-4; SD 1.2), AOFAS ankle and hindfoot scores averaged 89.6 out of 100 (range 86-100; SD 6.1). The pain subscale of the AOFAS score averaged 37.5 out of 40 (range 35-40; SD 2.5). The functional subscale of the AOFAS score averaged 46 out of 50 (range 44-50; SD 3.0). Stiffness was reported in one patient at their follow-up visits, which resolved with continued physical therapy. There were no superficial or deep infections. CONCLUSIONS In conclusion, this case series presents the first clinical outcomes of an all-suture fixation technique for treatment of unstable syndesmotic ankle injuries. Our results suggest that the all-suture fixation technique results in similar patient reported outcomes when compared with historically reported patient reported outcomes of suspensory suture button fixation, and low rates of complication or hardware failure.

Abstract
OBJECTIVE The objective of this study was to conduct a meta-analysis by synthesizing multiple literature sources to explore whether there are any differences between elastic fixation and rigid fixation in the treatment of acute tibiofibular syndesmosis injuries. The aim was to provide effective guidance for clinical treatment. METHODS We conducted a comprehensive search across seven databases, including both Chinese and English, to include all studies related to the treatment of acute tibiofibular syndesmosis injuries with elastic fixation and rigid fixation published between January 1, 2013, and November 15, 2022. Following the PRISMA guidelines, we rigorously screened, assessed, and extracted data from the included studies. The outcome measures included AOFAS scores at 3, 6, and 12 months postoperatively; tibiofibular clear space (TBCS) and tibiofibular overlap distance (TBOL) at the early postoperative and 12-month follow-up; intraoperative blood loss; operative time; time to full weight-bearing postoperatively; and postoperative complications. Meta-analysis was performed using Review Manager 5.4. RESULTS A total of 35 studies were included, comprising 16 randomized controlled trials and 19 retrospective cohort studies. The study population included 2120 cases, with 1044 cases in the elastic fixation group and 1076 cases in the rigid fixation group. The elastic fixation group had higher AOFAS scores at 3, 6, and 12 months postoperatively compared to the rigid fixation group. Although the elastic fixation group had a slightly larger TBCS than the rigid fixation group in the early postoperative period, the difference between the two groups became statistically insignificant at 12 months postoperatively. There was no statistically significant difference in TBOL between the two groups in the early postoperative period, but at 12 months, the elastic fixation group had a greater TBOL than the rigid fixation group. Additionally, the elastic fixation group had lower rates of postoperative local irritation, wound infection, and postoperative internal fixation loosening or rupture compared to the rigid fixation group. The rate of postoperative tibiofibular redislocation did not differ statistically between the two groups. The time to full weight-bearing was shorter in the elastic fixation group than in the rigid fixation group. Although the elastic fixation group had a slightly longer operative time, there was no statistically significant difference in intraoperative blood loss between the two groups. CONCLUSION Compared to rigid fixation, elastic fixation in the treatment of acute tibiofibular syndesmosis injuries offers several advantages, including better postoperative ankle joint function recovery, more precise anatomical reduction of the syndesmosis postoperatively, a lower incidence of postoperative complications, and shorter time to full weight-bearing postoperatively. These findings provide robust guidance for clinical treatment.

Abstract
The objective of this cadaveric biomechanical study was to evaluate if the center-center surgical technique is a reliable and repeatable method of achieving proper syndesmotic reduction when using dynamic syndesmotic fixation. Nine fresh frozen above-knee cadaveric lower extremities were used. Computerized tomography (CT) scans were first obtained for each intact specimen as the baseline for comparison. A simulated complete syndesmotic disruption was created by transection of all deltoid and syndesmotic ligaments. Instability of the ankle was confirmed with stress imaging using fluoroscopy. Each unstable specimen was repaired using the center-center surgical technique with dynamic syndesmosis fixation. A series of measurements from the axial CT images of intact and repaired specimens were used to determine the anatomic distal tibiofibular relationships for comparison of changes from intact to postfixation. All radiographic measurements were performed by 4 independent foot and ankle surgeons. The level of inter-rater reliability for all the measurements was found to be "moderate" to "excellent" agreement (ICC value: 0.865-0.983, 95% confidence interval: 0.634-0.996). There was no statistical difference found between rotational alignment of native and postfixation (a/b: p = .843; b-a: p = .125; θ: p = .062). There was a statistical difference detected for lateral alignment at the center of fibularis incisura between native and postfixation (average: -0.6 ± 0.8 mm, range: -2.3 to 1.2 mm, p < .001). There was no statistical difference found for the anteroposterior translation alignment between native and postfixation (d/e: p = .251; f: p = .377). This study demonstrated the use of the center-center surgical technique as a viable and repeatable method for achieving anatomical reduction of the tibiofibular syndesmosis when used with dynamic fixation modalities.

Abstract
The aim of this study was to estimate the time needed for patients with Maisonneuve fractures to return to routine activities, after treatment with a suture-button system stabilization combined with plate and arthroscopic assistance (SBPAA). Methods The study included 13 patients treated at our surgical department from January 2018 to June2022. Specific radiographical follow-up and periodic checks were performed in a short -to-medium term period, to evaluate syndesmosis evolution and tibiofibular overlap with medial clear space (MCS). Results Progressive recovery and improvement were observed during follow-up from both radiographic and clinical perspective. Data showed that patients were able to return to full weight-bearing walking around the ninth week and to sport activities in 7.5 months. Long-term complications associated with residual joint stiffness, complex regional pain syndrome, or wound complications were observed in three patients. Conclusions Intraoperative arthroscopy represent a valid diagnostic tool to better recognize and evaluate osteochondral lesions in case of syndesmosys. The study demonstrates the importance of intraoperative arthroscopy for recognizing and treating associated osteochondral lesions with proper syndesmosis evaluation. Plate associated to double TightRope represent valid solution to functionally fix and reduce fractures. Additionally, it imitates the normal syndesmosis's anatomy and provides elasticity and robustness, guaranteeing a rapid return to sporting activity. Data and casuistry support these findings.

Abstract
In placing the medial suture button for syndesmosis injury, the risk of great saphenous vein and saphenous nerve injury has been reported. This study aimed to determine the safe insertion angle of the guide pin to avoid saphenous structure injury during suture button fixation. The incidence of saphenous structure injury was investigated using 8 legs of cadavers. The greater saphenous vein was depicted on the skin using near-infrared light (VeinViewer® Flex) and the distance between the greater saphenous vein and the posterior edge of the tibia at levels of 10, 20, and 30 mm from the joint line of the tibiotalar joint was measured in the 60 legs of healthy participants. On computed tomography (CT) images, the angles between the greater saphenous vein and transmalleolar axis at levels of 10, 20, and 30 mm from the joint line of the tibiotalar joint were measured. The cadaveric study revealed that the percentages of contact with the saphenous nerve were 8.3% to 16.7%. Using near-infrared light, the vein and tibia distance was 32.9 ± 6.8 mm of 10 mm, 26.6 ± 6.4 mm of 20 mm, and 20.4 ± 6.4 mm of 30 mm. The angle between the vein and transmalleolar axis was 1.0° to 9.4°, and more proximal, the angle was smaller. The veins depicted by near-infrared light can be a landmark to identify great saphenous vein, and injury of the saphenous structure can be prevented using VeinViewer Flex or considering the insertion angle defined in this study when placing the suture button for syndesmosis injuries.Level of Evidence: Level IV.

Abstract
Ankle fractures are among the most common orthopaedic injuries. Operative management is performed in unstable ankle fracture patterns to restore the stability and native kinematics of the ankle mortise and minimize the risk of post-traumatic degenerative changes. In this study, we review current concepts in ankle fracture management, including posterior malleolus fixation, syndesmosis fixation, deltoid ligament repair, fibular nailing, and early weightbearing, from both a biomechanical and clinical perspective.

Abstract
BACKGROUND This study aims to evaluate the results and the safety of a novel fixation method we developed for syndesmosis injuries that we call the "embrace" technique. METHODS Between March 2018 and October 2020, a total of 67 patients with ankle fractures and syndesmotic injuries underwent syndesmosis fixation with the embrace technique at our institute. Plain radiographs and computed tomographic (CT) scans were obtained preoperatively. Postoperative radiographic assessment included anteroposterior (AP) and lateral radiographs and CT scans of both ankles. Additionally, the American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot Score, Olerud-Molander Ankle Score, and visual analog scale (VAS) score were used for postoperative assessment. RESULTS The mean age was 27.6 ± 10.9 (range, 14-56) years. The mean follow-up time was 30.3 ± 6.2 (range, 24-48) months. There were no malreductions indicated by any CT parameter except fibular rotation in a postoperative comparison between 2 sides. We found significant preoperative-postoperative changes in anterior difference, posterior difference, and fibular rotation but no significant preoperative-postoperative difference in fibular translation. There was no significant postoperative difference between the affected-side and normal-side measurements of any parameter. Complications included delayed wound healing, lateral pain because of wire knot irritation (11.9%), and medial fiber wire irritation (7.5%). The mean AOFAS, Olerud-Molander, and VAS scores at the last follow-up were 94.4 ± 6.8 (range, 84-100), 95.4 ± 6.1 (range, 80-100), and 0.68 ± 1.0 (range, 0-3) points, respectively. CONCLUSION In our cohort, this novel technique proved to be an effective method for syndesmosis fixation in patients with ankle fractures associated with very good radiologic and patient-reported outcomes.

Abstract
PURPOSE Syndesmotic injuries are associated with long recovery times and high morbidity. Systematic reviews show a trend toward better outcomes of suture buttons compared to screw fixation. The anteroinferior tibiofibular ligament (AITFL) confers the most significant component of translational and rotatory stability. Techniques have developed which reinforce the AITFL. This study aimed to assess results of syndesmotic stabilisation with dynamic stabilisation and reinforcement of the AITFL, with an early mobilisation program. MATERIALS AND METHODS Retrospective case series of 30 patients (mean age 31 years). Syndesmotic instability was confirmed with clinical examination, MRI and weightbearing-CT. Dynamic syndesmotic stabilisation with a single suture button was performed followed by the placement of an Internal Brace over the AITFL. A standardised postoperative rehabilitation protocol was established. Foot and Ankle Ability Measure (FAAM) scores were collected postoperatively. RESULTS The average follow-up was 13 months. The total FAAM score for ADL was 95 ± 4.9 % (range, 83 - 100 %) and for sport activities 87 ± 13.6 % (range, 50 - 100 %). The rating of mean postoperative function for ADL was 94 ± 5.5 % (range, 80 - 100 %) and 90 ± 13 % (range, 35 - 100 %) for sportv. The difference between acute and chronic injuries was statistically higher (p < 0.05) for daily activities and sport, but the rating of current level of sport activites as well as for daily activites did not show a significant difference (p = 0.9296 and p = 0.1615, respectively). Twenty-seven patients (90 %) rated their overall current level of function as normal or nearly normal. CONCLUSION This technique aims to directly stabilise the AITFL and the interosseous components of the syndesmosis, and allow early mobilisation and return to sport at 10 weeks. Early results show the procedure is safe, with comparable results to the literature. Acute injuries showed better results of the FAAM score than chronic injuries.

Abstract
BACKGROUND Over the past 30 years, several studies have compared early weight-bearing versus late weight-bearing following open reduction and internal fixation of ankle fractures; however, no review strictly including patients with ankle fractures and complete syndesmotic disruption has been performed. OBJECTIVE The objective of this systematic review was to compare early versus late weight-bearing following surgery for ankle fracture with syndesmotic injury regarding clinical and patient-reported outcomes. METHODS A comprehensive search strategy was applied to the Cochrane Library, MEDLINE, Embase, CINAHL and PubMed databases from their inception to the 17th of January 2022. The articles were screened independently by two blinded reviewers. Data were extracted by one author, then cross-checked and approved by the other. RESULTS No comparative studies were found; therefore, studies describing either early or late weight-bearing were included. It was thus not possible to perform a meta-analysis. 11 studies and 751 patients were included. An early partial weight-bearing protocol was used in three studies (253 patients) and late in eight studies (498 patients). Functional outcomes suggested that there were no clear differences between early partial weight-bearing and late weight-bearing. The reoperation rate was 9-31% in the early group and 0-11% in the late. Similar results were seen for loss of syndesmotic reduction, malreduction, infection, and fixation failure. CONCLUSION Pros and cons were reported for early partial weight-bearing and late weight-bearing, but the evidence was very limited as our results were based on noncomparative studies. In the future, high-quality comparative studies focusing on functional outcomes within 6 months postoperatively are needed. LEVEL OF CLINICAL EVIDENCE 1.

Abstract
Background: Syndesmotic injuries are common lesions associated with ankle fractures. Static and dynamic fixation are frequently used in syndesmotic injury-associated ankle fractures. The purpose of this study is to compare short- and mid-term quality of life, clinical outcomes, and gait after static stabilization with a trans-syndesmotic screw or dynamic stabilization with a suture button device. Methods: Here, 230 patients were enrolled in a retrospective observational study. They were divided in two groups according to the fixation procedure (Arthrex TightRope®, Munich, Germany) synthesis vs. osteosynthesis with a 3.5 mm trans-syndesmotic tricortical screw). They then underwent clinical assessment using the American Foot and Ankle Score (AOFAS) at 1, 2, 6, 12, and 24 months after surgery. Quality of life was assessed according to the EuroQol-5 Dimension (EQ-5D) at 2 and 24 months after surgery in the follow-up; gait analysis was performed 2 and 24 months postoperatively. Results: Significant differences were found at a two-month follow-up according to the AOFAS (p = 0.0001) and EQ-5D (p = 0.0208) scores. No differences were noted in the other follow-ups (p > 0.05) or gait analysis. Conclusion: The dynamic and static fixation of syndesmotic injuries in ankle fracture are both efficacious and valid procedures for avoiding ankle instability. The suture button device was comparable to the screw fixation according to functional outcomes and gait analysis.

Abstract
The distal tibiofibular syndesmosis (DTFS) is more frequently injured than previously thought. Early diagnosis and appropriate treatment is essential to avoid long term complications like chronic instability, early osteoarthritis and residual pain. Management of these injuries require a complete understanding of the anatomy of DTFS, and the role played by the ligaments stabilizing the DTFS and ankle. High index of suspicion, appreciating the areas of focal tenderness and utilizing the provocative maneuvers help in early diagnosis. In pure ligamentous injuries radiographs with stress of weight bearing help to detect subtle instability. If these images are inconclusive, then further imaging with MRI, CT scan, stress examination under anesthesia, and arthroscopic examination facilitate diagnosis. An injury to syndesmosis frequently accompanies rotational fractures and all ankle fractures need to be stressed intra-operatively under fluoroscopy after fixation of the osseous components to detect syndesmotic instability. Non-operative treatment is appropriate for stable injuries. Unstable injuries should be treated operatively. Anatomic reduction of the syndesmosis is critical, and currently both trans-syndesmotic screws and suture button fixation are commonly used for syndesmotic stabilization. Chronic syndesmotic instability (CSI) requires debridement of syndesmosis, restoration of ankle mortise with or without syndesmotic stabilization. Arthrodesis of ankle is used a last resort in the presence of significant ankle arthritis. This article reviews anatomy and biomechanics of the syndesmosis, the mechanism of pure ligamentous injury and injury associated with ankle fractures, clinical, radiological and arthroscopic diagnosis and surgical treatment.

Abstract
INTRODUCTION Although non-fracture-related syndesmotic injuries of the ankle are relatively rare, they may lead to poor clinical outcome if initially undiagnosed or managed improperly. Despite a variety of literature regarding possibilities for treatment of isolated syndesmotic injuries, little is known about effective applications of different therapeutic methods in day-to-day work. The aim of this study was to assess the current status of the treatment of isolated syndesmotic injuries in Germany. MATERIALS AND METHODS An online-questionnaire, capturing the routine diagnostic workup including clinical examination, radiologic assessment and treatment strategies, was sent to all members of the German Society of Orthopedic Surgery and Traumatology (DGOU) and Association of Arthroscopic and Joint Surgery (AGA). Statistical analysis was performed using Microsoft excel and SPSS. RESULTS Each question of the questionnaire was on average answered by 431 ± 113 respondents. External rotation stress test (66%), squeeze test (61%) and forced dorsiflexion test (40%) were most commonly used for the clinical examination. In the diagnostic workup, most clinicians relied on MRI (83%) and conventional X-ray analysis (anterior-posterior 58%, lateral 41%, mortise view 38%). Only 15% of the respondents stated that there is a role for arthroscopic evaluation for the assessment of isolated syndesmotic injuries. Most frequently used fixation techniques included syndesmotic screw fixation (80%, 42% one syndesmotic screw, 38% two syndesmotic screws), followed by suture-button devices in 13%. Syndesmotic screw fixation was mainly performed tricortically (78%). While 50% of the respondents stated that syndesmotic screw fixation and suture-button devices are equivalent in the treatment of isolated syndesmotic injuries with respect to clinical outcome, 36% answered that syndesmotic screw fixation is superior compared to suture-button devices. CONCLUSIONS While arthroscopy and suture-button devices do not appear to be widely used, syndesmotic screw fixation after diagnostic work-up by MRI seems to be the common treatment algorithm for non-fracture-related syndesmotic injuries in Germany.

Comparison of a Novel Modified All-Suture Construct versus Suspensory Suture-button Fixation in a Syndesmotic Injury Model. J Orthop Trauma 2023; 37:e104-e110. [PMID: 36219777 DOI: 10.1097/bot.0000000000002503] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 10/06/2022] [Indexed: 02/02/2023]
Abstract
OBJECTIVES To biomechanically investigate a novel modified all-suture construct compared with commercially available suspensory button fixation for stabilization of the syndesmosis. METHODS Eight matched pairs of cadaver lower limbs were obtained. We used a material testing machine and Optotrak optoelectronic 3D motion measurement system for testing. Syndesmotic injuries were simulated, and specimens were fixed with either a suspensory suture button or modified all-suture construct. Repaired specimens were then cyclically loaded for 500 cycles. Spatial relationship of the tibia and fibula were continuously monitored for the intact, destabilized, and repaired states. The results were analyzed using independent samples t test. RESULTS There was no significant difference in sagittal or coronal plane translation between intact and either repair. Compared with the intact state, both repair techniques demonstrated significantly more external rotation of the fibula relative to the tibia and decreased construct stiffness. Cycling of the specimens did not significantly increase coronal or sagittal plane translation; however, external rotation of the fibula relative to the tibia increased and stiffness decreased with cycling for both repair techniques. CONCLUSIONS Our data suggest that sagittal and coronal plane translation is no different from the intact state for both fixation techniques. However, rotation of the fibula relative to the tibia was increased, and construct stiffness was decreased compared with the intact state for both fixation techniques. These findings suggest that an all-suture construct could offer syndesmotic fixation comparable with proprietary suspensory button fixation in a cadaver model.

What is the best treatment for syndesmosis fixation? Suture-button or syndesmotic screw ? Bilateral CT-based early postoperative analysis. Foot Ankle Surg 2023; 29:128-135. [PMID: 36535844 DOI: 10.1016/j.fas.2022.12.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 11/22/2022] [Accepted: 12/07/2022] [Indexed: 12/13/2022]
Abstract
BACKGROUND The aim of this study was to compare the effectiveness of syndesmotic screw (SS) and suture button (SB) on the reduction and fixation of syndesmosis via early postoperative bilateral computed tomography (CT). METHODS This single-center retrospective study included 76 patients aged ≥ 18 years with a unilateral syndesmosis injury. SS was applied to 40 patients and SB to 36 patients. The differences between the sides stabilized using SB or SS and the intact sides were analyzed using the parameters of tibio-fibular clear space (∆CS) and anterior or posterior sagittal translation (∆ST) depending on the orientation of the fibula. The cases in which the fibula was translocated to the posterior of the tibia after the change of ∆ST and ∆CS> 2 mm were evaluated as malreduction. Axial CT images taken from the level of syndesmosis fixation were divided into 4 zones according to the orientation angle of the implant sent from the fibula to the tibia. RESULTS No significant difference was found in the analyses performed between total patient group with malreduction and fixation groups in terms of ∆CS and ∆ST values (p = 0.708, p = 0.289). It was observed that the fixation material was in zone 3 in 54 patients and in zone 2 in 22 patients. No significant difference was found in the analyses performed between the SS and SB groups according to the implant zone (p = 0.191). In the SS group sent from Zone 2, the malreduction rate according to the ∆ST value of syndesmosis was found to be significantly higher than in the SB group (p = 0.008, p = 0.003). CONCLUSION When the implant is applied with the correct technique, there is no difference between SS and SB in terms of early postoperative reduction. When the SS is advanced at an inappropriate angle, it negatively affects the reduction of the fibula, while SB can better tolerate angle errors up to certain degrees due to its flexible structure. Therefore, it can be presumed that the suture button system is a more convenient method in the reduction and fixation of syndesmosis than the syndesmotic screw. LEVEL OF EVIDENCE Level IV.

Abstract
OBJECTIVE The distal tibiofibular syndesmosis (DTS) is a fretting joint and it is still a hot issue how to satisfy strong internal fixation while allowing fretting. This study described and evaluated a new method for elastic fixation of DTS injury with Nice Knot. METHODS The study was designed as a retrospective study. Between June 2020 and June 2021, 31 patients who were diagnosed with ankle fracture and DTS injury without additional orthopedic injuries were enrolled in this case series. The study included 22 males and nine females, with an average age of 34.71 ± 14.66 years. All patients were treated with Nice Knot binding for DTS. Surgical time, length of stay, time of DTS fixation, total weight-bearing time, complications, imaging parameters, and functional scores at follow-up were recorded. Paired sample t-tests or single factor analyses of variance were used at intra-group comparison. RESULTS All patients completed surgery with normal syndesmotic parameters. The recovery of DTS injury was verified by Hook and lateral malleolus rotation tests. The average follow-up time was 15.97 ± 3.30 months. Only one case showed superficial infection after surgery, and the wound healed after symptomatic treatment. In terms of imaging, there were no significant differences in tibiofibular clear space (TFCS), tibiofibular overlap distance (TFOS), medial clear space (MCS), and superior clear space (SCS) immediately and at different follow-up points after surgery. All obtained excellent and good outcomes according to the AOFAS score at least follow-up after surgery. CONCLUSIONS Nice Knot elastic fixation of DTS injury is firm and stable while maintaining the physiological micromotion of the ankle joint.

Abstract
Background The syndesmotic screw (SS) and suture button (SB) fixation methods are both widely used for the reduction of ankle syndesmotic injury, with varying outcomes. Purpose To review recently published randomized controlled trials (RCTs) to assess the outcomes between SS and SB fixation for ankle syndesmotic injury. Study Design Systematic review; Level of evidence, 1. Methods The PubMed, Embase, ClinicalTrials.gov, and Cochrane databases were searched for relevant RCTs published between 1966 and 2021 according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Eligible studies were RCTs comparing SS and SB fixation for ankle syndesmotic injury. The risk of bias was evaluated using the Cochrane Risk of Bias tool. Primary outcomes included complications, malreduction, and unplanned reoperation, and secondary outcomes were the American Orthopaedic Foot & Ankle Society (AOFAS) score, Olerud-Molander ankle score (OMAS), and EuroQol-5 Domain (EQ-5D) score. The mean difference (MD) and risk ratio (RR) were calculated for continuous and dichotomous outcomes, respectively. Random- or fixed-effects model was applied according to heterogeneity. Results Of 389 studies, 8 RCTs involving 512 patients were included. Overall, 257 patients received SS fixation and 255 patients received SB fixation. The 2 groups did not differ significantly in malreduction (RR, -0.06; 95% CI, -0.18 to 0.07) or EQ-5D (MD, 0.01; 95% CI, -0.01 to 0.03). However, the SB group showed significant advantages over the SS group in complications (RR, 0.42; 95% CI, 0.26 to 0.66), unplanned reoperation (RR, 0.62; 95% CI, 0.43 to 0.89), AOFAS score (MD, 3.04; 95% CI, 1.77 to 4.31), and OMAS (MD, 4.51; 95% CI, 1.54 to 7.48). The risk of bias of the included studies was acceptable. Conclusion The results showed that there were no significant differences between the SS and SB groups in malreduction and EQ-5D scores. However, the SB group had significantly better local irritation rates, unplanned reoperation rates, AOFAS scores, and OMASs.

Abstract
BACKGROUND The quality of reduction of the distal tibiofibular joint (DTFJ) has a major impact on the outcome. Novel suture-button systems as well as intraoperative 3D imaging can be applied to increase the quality of DTFJ reduction intraoperatively. The individual effect of either remains unknown. The aim of this study was to investigate the value of intraoperative 3D imaging on the quality of reduction of the DTFJ when using a suture-button system. METHODS Retrospective, radiographic study including adult patients who underwent surgical stabilization of the syndesmosis with a suture-button system for acute, unilateral, unstable syndesmotic injuries with postoperative bilateral CT imaging. The use of an intraoperative 3D scan was the individual surgeon's choice. Assessed was whether the intraoperative 3D imaging had an influence on the postoperative quality of DTFJ reduction and revision rates. These findings were put in perspective to the correction potential of the suture-button system. RESULTS A total of 147 patients were included; 76 of these received an intraoperative 3D imaging. Neither the rate of formal malreduction (17% vs 17%) nor the postoperative revision rate (4% vs 3%) differed significantly between patients with or without intraoperative 3D imaging. Intraoperative 3D imaging revealed a false-negative rate of 14%. The intrinsic correction potential of the suture-button system reduced the number of formally malreduced DTFJs in both groups by 51%. CONCLUSION The additional value of intraoperative 3D imaging to assess the quality of DTFJ reduction in our series did not improve syndesmotic reduction when using a flexible suture-button system.

Abstract
BACKGROUND There is an ongoing discussion on how to best stabilize syndesmotic injuries. Previous studies have indicated a better quality of reduction of the distal tibiofibular joint (DTFJ) for the suture button systems compared to syndesmotic screw fixation. Still, the reason for this superiority remains unclear. The aims of this retrospective study were to (1) analyze the deviation of the tibial and fibular drilling tunnels of the suture button system and (2) to compare these to the quality of reduction of the DTFJ assessed on bilateral postoperative CT images. METHODS Included were all adult patients who underwent syndesmotic stabilization for an acute injury using a suture button system, with postoperative, bilateral CT imaging over a 10-year period. A total of 147 patients were eligible. Based on individually reconstructed axial CT slices, the postoperative quality of reduction of the DTFJs was rated on bilateral CT images. Furthermore, the rotation and translation of the suture button drilling tunnels were analyzed. Based on these measurements, the intraoperative reduction of the DTFJ was recalculated and again rated. Using these values, the correction potential of suture button systems on the reduction of the DTFJ was analyzed. RESULTS (1) The drilling tunnel deviated considerably for both rotation |2.3±2.1 degrees| (range: |0.0-13.1 degrees|) and translation |0.9±0.8 mm| (range: |0-4.3 mm|). Based on the deviation of the drilling tunnels in fibula and tibia, the calculated intraoperative reduction of the DTFJ was classified as malreduced in 35.4%. (2) The DTFJ was postoperatively identified as malreduced in 17% of patients. Overall, the suture button system tended to compensate toward a more anatomical reduction both in the axial and sagittal plane. CONCLUSION A suture button system postoperatively deviates and apparently has the capacity to compensate for intraoperative malreduction. Analysis of the drilling tunnels revealed that the use of a rigid fixation system would have doubled the postoperative malreduction rate.

“Flexible nature of fixation” in syndesmotic stabilization of the inferior tibiofibular joint affects the radiological reduction outcome. INTERNATIONAL ORTHOPAEDICS 2022; 46:2649-2657. [PMID: 35982324 PMCID: PMC9556355 DOI: 10.1007/s00264-022-05550-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/04/2022] [Accepted: 08/11/2022] [Indexed: 11/01/2022]
Abstract
Abstract
Purpose
Fibular mobility after suture button stabilization (SBS) of inferior tibiofibular joint (syndesmosis) injuries has been described. This effect is called the “flexible nature of fixation (FNF).” In this study, we aimed to quantify FNF in syndesmotic stabilization.
Methods
Postoperative bilateral computed tomography (CT) of ankle fractures with syndesmosis stabilization by SBS or syndesmotic screw (SYS) was retrospectively analyzed. The transverse offset (TO) and vertical offset (VO) were defined by evaluating the drill channels. The reduction outcome was evaluated by the side-to-side difference between the clear space and the anterior tibiofibular distance (antTFD). The calculated anterior tibiofibular distance (cal-antTFD) was calculated by subtracting the TO from the validated antTFD. Subsequently, a reevaluation of the reduction outcomes after SYS or SBS stabilization was performed using cal-antTFD.
Results
Sixty patients (44 with SBS and 16 with SYS stabilization) were analyzed. The intra-rater and inter-rater reliabilities for TO and VO were excellent (α > 0.92). SYS stabilization showed lower mean TO (− 0.02 mm; SD 0.14) and VO (0.11 mm; SD, 0.29 mm) than SBS stabilization (TO 1.16 mm, SD 1.4 mm; VO 0.2 mm, SD 0.8 mm; p = 0.001). The rate of malreduction according to cal-antTFD was higher than that of antFTD (p = 0.033).
Conclusion
The presented method, which evaluates the position of the tibial to the fibular drill channel, allowed the quantification of the “FNF.” The often described difference in the dynamic stabilization of SBS compared to the rigid stabilization by SYS could be objectified. Considering cal-antTFD illustrates that FNF potentially reduces the rate of malreduction in SBS stabilization.

The Effect of Stabilization Procedures on Sports Discipline and Performance Level in Non-Elite Athletes after Acute Syndesmotic Injury: A Prospective Randomized Trial. J Clin Med 2022; 11:jcm11154609.

Abstract
BACKGROUND Suture button devices for tibiofibular syndesmosis injuries provide semirigid dynamic stabilization. The effect of stabilization procedures on sports discipline and performance level in non-elite athletes after acute syndesmotic injury has not been clarified in sports medicine research to date. METHODS A total of 47 of 56 eligible patients were analyzed and completed the 1-year follow-up. The average age was 35.5 years (range, 18-60 years). The screw fixation and knotless suture button groups comprised 26 and 21 patients, respectively. Nine patients were lost to follow-up. Patients underwent clinical and radiological evaluations preoperatively and twice during the 1-year postoperative follow-up. Function was measured using the FADI sports scale, the FAAM sports module, and a visual analogue scale for pain and function in sports. Questionnaires were completed to assess preoperative and postoperative sports levels and to evaluate the sports discipline. RESULTS All scores increased during the follow-up, but no significant differences were found in the FADI score, the FAAM sports module score and or the VAS score for pain and function during sport (p ≤ 0.05). Using Spearman's rank correlation coefficient, we found no significant correlation between the groups for age, injury mechanism, or body mass index. Differences were identified in sports discipline and performance level between the groups during the follow-up period. CONCLUSION No statistically significant differences could be demonstrated between the two stabilization methods in terms of return to previous sport level and return to the original sport discipline, so both procedures can be regarded as equivalent at present.

Comparison of Several Combinations of Suture Tape Reinforcement and Suture Button Constructs for Fixation of Unstable Syndesmosis. J Am Acad Orthop Surg 2022; 30:e769-e778.

Abstract
INTRODUCTION The purpose of this study was to arthroscopically evaluate syndesmotic stability after fixation with several combinations of suture buttons (SBs) and suture tape reinforcement in a completely unstable cadaver model. METHODS Fifteen cadaver above-knee specimens underwent sequential ligament transection and fixation to create six experimental models: (1) intact model, (2) after complete disruption of the syndesmotic ligaments, and after repair with either suture tape reinforcement (3), suture tape reinforcement with a single SB (4), suture tape reinforcement with two diverging SBs (5), or two diverging SBs alone (6). Instability measurements included anterior and posterior tibiofibular spaces measured arthroscopically under 100 N coronal stress, tibiofibular anteroposterior and posteroanterior translation in sagittal plane measured arthroscopically under sagittal stress of 100 N, and anterior tibiofibular space measured directly with a caliper under external rotation torque of 7.5 N·m. Instability measurements taken after each fixation method were compared with the uninjured model and with the complete unstable model using the Wilcoxon signed-rank test. RESULTS Fixation using a combination of one SB and singular suture tape reinforcement augmentation provided stability similar to the intact stage (coronal anterior space 1.24 versus 1.15, P = 0.887; coronal posterior space 1.63 versus 1.64, P = 0.8421; anteroposterior translation 0.91 versus 0.46, P = 0.003; posteroanterior translation 0.51 versus 0.57, P = 0.051; external rotation anterior tibiofibular space 1.08 versus 0.55, P = 0.069). Moreover, adding a second SB led to further gains in fixation stability. DISCUSSION This study suggests that although a destabilizing syndesmotic injury that includes the anterior inferior tibiofibular ligament, interosseous ligament, and posterior inferior tibiofibular ligament is not adequately stabilized by either one or two SBs, the addition of a suture tape reinforcement to even one SB restores syndesmotic stability to the preinjury level.

Abstract
INTRODUCTION Maintaining reduction after syndesmotic injury is crucial to patient function; however, malreduction remains common. Flexible suture button fixation may allow more physiologic motion of the syndesmosis compared with rigid screw fixation. Conventional syndesmotic imaging fails to account for physiologic syndesmotic motion with ankle range of motion (ROM), providing misleading results. Four-dimensional computerized tomography (4DCT) can image joints through a dynamic ROM. Our purpose was to compare syndesmotic motion after rigid and flexible fixation using 4DCT. METHODS We analyzed 13 patients with syndesmotic injury who were randomized to receive rigid (n = 7) or flexible (n = 6) fixation. Patients underwent bilateral ankle 4DCT while moving between ankle dorsiflexion and plantar flexion. Measures of syndesmotic position and rotation were extracted from 4DCT to determine syndesmotic motion as a function of ankle ROM. RESULTS Uninjured ankles demonstrated significant decreases in syndesmotic width of 1.0 mm with ankle plantar flexion (SD = 0.6 mm, P < 0.01). Initial rigid fixation demonstrated reduced motion compared with uninjured ankles in 4 of 5 measures (P < 0.01) despite all patients in the rigid fixation group having removed, loose, or broken screws by the time of imaging. Rigid fixation led to less motion than flexible fixation in 3 measures (P = 0.02-0.04). There were no observed differences in syndesmotic position or motion between flexible fixation and uninjured ankles. CONCLUSION Despite the loss of fixation in all subjects in the rigid fixation group, initial rigid fixation led to significantly reduced syndesmotic motion. Flexible fixation recreated more physiologic motion compared with rigid fixation and may be used to reduce rates of syndesmotic malreduction. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
Background: Acute syndesmosis injury (ASI) is an indication for surgical stabilization if instability is confirmed. In recent years, fixation using the knotless suture-button (SB) device has become increasingly established as an alternative to set screw fixation (SF). This study directly compared the clinical long-term results after prospective randomized inclusion. Materials and Methods: Between 2011 and 2012, 62 patients with ASI were enrolled in a prospective, randomized, and monocentric study. Forty-one patients were available for a 10-year follow-up ((31 males and 10 females), including 21 treated with SB (mean age 44.4 years), and 20 with SF (mean age 47.2 years)). In addition to comparing the demographic data and syndesmosis injury etiology, follow-up assessed the Olerud−Molander Ankle Score (OMAS) and FADI-Score (Foot and Ankle Disability Index Score) with subscales for activities of daily living (ADL) and sports activity. Results: The mean OMAS was 95.98 points (SB: 98.81, SF: 93.00), the mean FADI ADL was 97.58 points (SB: 99.22, SF: 95.86), and the mean FADI Sport was 94.14 points (SB: 97.03, SF: 91.10). None of the measurements differed significantly between the groups (p > 0.05). No clinical suspicion of chronic instability remained in any of the patients, regardless of treatment. Conclusions: The short-term results showed that athletes in particular benefit from SB fixation due to their significantly faster return to sports activities. However, the available long-term results confirm a very good outcome in the clinical scores for both approaches. Chronic syndesmotic insufficiency was not suspected in any of the patients. Level of evidence: I, randomized controlled trial.

Abstract
» Maisonneuve fractures (MFs), originally described as subcapital (high) fibular fractures with additional injury to the anterior and interosseous tibiofibular ligaments, display a variable injury pattern, ranging from stable to highly unstable fractures. » The high incidence of associated fractures of the posterior malleolus, the medial malleolus, and the anterolateral distal tibia (the "anterior malleolus") as well as the variable position of the fibula in the fibular notch (FN) warrant preoperative examination via computed tomography (CT). » The main goal of treatment is anatomic reduction of the distal fibula into the FN, which requires prior reduction of displaced posterior malleolar fractures, if present, to restore the integrity of the FN. » Open reduction of the distal fibula into the FN and fixation with 2 transsyndesmotic screws or fixation with a screw(s) and suture-button implant, under direct vision, on the lateral aspect of the ankle joint and anterior tibiofibular alignment are preferred over closed reduction to avoid sagittal or rotational malpositioning, which is associated with an inferior outcome. » Intra- or postoperative 3D CT visualization is essential for assessment of the accuracy of the reduction of the distal fibula into the FN.

Abstract
Background: Surgical treatment of unstable syndesmotic injuries is not trivial, and there are no generally accepted treatment guidelines. The most common controversies regarding surgical treatment are related to screw fixation versus dynamic fixation, the use of reduction clamps, open versus closed reduction, and the role of the posterior malleolus and of the anterior inferior tibiofibular ligament (AITFL). Our aim was to draw important conclusions from the pertinent literature concerning surgical treatment of unstable syndesmotic injuries, to transform these conclusions into surgical principles supported by the literature, and finally to fuse these principles into an evidence-based surgical treatment algorithm. Methods: PubMed, Embase, Google Scholar, The Cochrane Database of Systematic Reviews, and the reference lists of systematic reviews of relevant studies dealing with the surgical treatment of unstable syndesmotic injuries were searched independently by two reviewers using specific terms and limits. Surgical principles supported by the literature were fused into an evidence-based surgical treatment algorithm. Results: A total of 171 articles were included for further considerations. Among them, 47 articles concerned syndesmotic screw fixation and 41 flexible dynamic fixations of the syndesmosis. Twenty-five studies compared screw fixation with dynamic fixations, and seven out of these comparisons were randomized controlled trials. Nineteen articles addressed the posterior malleolus, 14 the role of the AITFL, and eight the use of reduction clamps. Anatomic reduction is crucial to prevent posttraumatic osteoarthritis. Therefore, flexible dynamic stabilization techniques should be preferred whenever possible. An unstable AITFL should be repaired and augmented, as it represents an important stabilizer of external rotation of the distal fibula. Conclusions: The current literature provides sufficient arguments for the development of an evidence-based surgical treatment algorithm for unstable syndesmotic injuries.

Abstract
Background Ankle fractures are common fractures in trauma surgery. Several studies have compared gait patterns between affected patients and control groups. However, no one used the Heidelberg Foot Measurement Method in combination with statistical parametric mapping of the entire gait cycle in this patient cohort. We sought to identify possible mobility deficits in the tibio-talar joint and medial arch in patients after ankle fractures as a sign of stiffness and pain that could result in a pathological gait pattern. We focused on the tibio-talar flexion as it is the main movement in the tibio-talar joint. Moreover, we examined the healing progress over time. Methods Fourteen patients with isolated ankle fractures were included prospectively. A gait analysis using the Heidelberg Foot Measurement Method was performed 9 and 26 weeks after surgery to analyse the tibio-talar dorsal flexion, the foot tibia dorsal flexion, the subtalar inversion and the medial arch as well as the cadence, the walking speed and the ground reaction force. The American Orthopedic Foot & Ankle Society ankle hindfoot score was used to obtain clinical data. Results were compared to those from 20 healthy participants. Furthermore, correlations between the American Orthopedic Foot & Ankle Society hindfoot score and the results of the gait analysis were evaluated. Results Statistical parametric mapping showed significant differences for the Foot Tibia Dorsal Flexion for patients after 9 weeks (53–75%: p = 0.001) and patients after 26 weeks (58–70%: p = 0.011) compared to healthy participants, respectively. Furthermore, significant differences regarding the tibio-talar dorsal flexion for patients 9 weeks after surgery (15–40%: p < 0.001; 56,5–70%: p = 0.007; 82–88%: p = 0.033; 97–98,5%: p = 0.048) as well as patients after 26 weeks (62,5–65%: p = 0.049) compared to healthy participants, respectively. There were no significant differences looking at the medial arch and the subtalar inversion. Moreover, significant differences regarding the ground reaction force were found for patients after 9 weeks (0–17%: p < 0.001; 21–37%: p < 0.001; 41–54%: p < 0.001; 60–64%: p = 0.013) as well as patients after 26 weeks (0–1,5%: p = 0.046; 5–15%: p < 0.001; 27–33%: p = 0.001; 45–49%: p = 0.005; 57–59%: p = 0.049) compared to healthy participants, respectively. In total, the range of motion in the tibio-talar joint and the medial arch was reduced in affected patients compared to healthy participants. Patients showed significant increase of the range of motion between 9 and 26 weeks. Conclusions This study shows, that patients affected by ankle fractures show limited mobility in the tibio-talar joint and the medial arch when compared to healthy participants. Even though the limitation of motion remains at least over a period of 26 weeks, a significant increase can be recognized over time. Furthermore, if we look at the absolute values, the patients’ values tend to get closer to those of the control group. Trial registration This study is registered at the German Clinical Trials Register (DRKS00023379).

Abstract
Patient preference for fixation technique of syndesmotic injury in the presence of an ankle fracture is not known. This study followed a five-step process for expected value decision analysis: decision tree, outcome probabilities, expected patient values, foldback analysis, and sensitivity analysis. Outcome variables were "well" (cases that did not require further procedures or suffer any complications related to surgery), surgical site infection (SSI), loss of reduction (LOR), hardware removal (HWR), and malreduction. The systematic review included 22 studies including 358 patients who underwent suture button fixation and 739 who underwent screw fixation. Outcome probabilities for suture button fixation were 76.4% well, 6.2% SSI, 5.4% LOR, 10.4% HWR, and 1.6% malreduction. Outcome probabilities for screw fixation were 47.1% well, 4.3% SSI, 8.1% LOR, 30.7% HWR, and 9.8% malreduction. After the survey and foldback analysis, overall utility values for suture button and screw fixation were 7.46 and 4.78, respectively. One-way sensitivity analysis revealed that the overall utility value for suture button fixation was greater than the utility value of screw fixation under all circumstances except when the rate of malreduction for suture button fixation was theoretically elevated to 85%. Level of evidence: therapeutic, level IV.

Abstract
BACKGROUND Inadequate reduction of syndesmotic injuries can result in disabling clinical outcomes. The aim of the study was to compare syndesmosis congruity after fixation by syndesmotic screws (SYS) or a suture button system (SBS) using three-dimensional (3D) computed imaging techniques. METHODS In a retrospective single-center study, patients with unilateral stabilization of an ankle fracture with a syndesmotic injury and post-operative bilateral CT scans were analyzed using a recently established 3D method. The side-to-side differences were compared for tibio-fibular clear space (∆CS), translation angle (∆α), and vertical offset (∆z) among patients stabilized with syndesmotic screws or suture button system. Syndesmotic malreduction was defined for ∆CS > 2 mm and for |∆α| > 5°. ∆CS and ∆α were correlated with two-dimensional (2D) measurements. RESULTS Eighteen patients stabilized with a syndesmosis screw and 29 stabilized with a suture button system were analyzed. After stabilization, both groups revealed mild diastasis (SYS: mean ∆CS 0.3 mm, SD 1.1 mm vs SBS: mean ∆CS 0.2 mm, SD 1.2 mm, p = 0.710). In addition, both stabilization methods showed slight dorsalization of the fibula (SYS: mean ∆α 0.5°, SD 4.6° vs SBS: mean ∆α 2.1°, SD 3.7°, p = 0.192). Also, restoration of the fibula-to-tibia length ratio also did not differ between the two groups (SYS: mean Δz of 0.5 mm, SD 2.4 mm vs SBS: mean Δz of 0 mm, SD 1.2 mm; p = 0.477). Malreduction according to high ∆α was most common (26% of cases), with equal distribution between the groups (p = 0.234). ∆CS and ∆α showed good correlation with 2D measurements (ρ = 0.567; ρ = 0.671). CONCLUSION This in vivo analysis of post-operative 3D models showed no differences in immediate post-operative alignment after syndesmotic screws or suture button system. Special attention should be paid to syndesmotic malreduction in the sagittal orientation of the fibula in relation to the tibia in radiological control of the syndesmotic congruity as well as intra-operatively.

Abstract
BACKGROUND The syndesmosis ligament complex stabilizes the distal tibiofibular joint while allowing for small amounts of physiologic motion. When injured, malreduction of the syndesmosis is the most important factor that contributes to inferior functional outcomes. Syndesmotic reduction is a dynamic measure, which is not adequately captured by conventional computed tomography (CT). Four-dimensional CT (4DCT) can image joints as they move through range of motion (ROM). The aim of this study was to employ 4DCT to determine in vivo syndesmotic motion with ankle ROM in uninjured ankles. METHODS Uninjured ankles were analyzed in patients who had contralateral syndesmotic injuries, as well as a cohort of healthy volunteers with bilateral uninjured ankles. Bilateral ankle 4DCT scans were performed as participants moved their ankles between maximal dorsiflexion and plantarflexion. Multiple measures of syndesmotic width, as well as sagittal translation and fibular rotation, were automatically extracted from 4DCT using a custom program to determine the change in syndesmotic position with ankle ROM. RESULTS Fifty-eight ankles were analyzed. Measures of syndesmotic width decreased by 0.7 to 1.1 mm as the ankle moved from dorsiflexion to plantarflexion (P < .001 for each measure). The fibula externally rotated by 1.2 degrees with ankle ROM (P < .001), but there was no significant motion in the sagittal plane (P = .43). No participants with bilateral uninjured ankles had a side-to-side difference in syndesmotic width of 2 mm or greater. CONCLUSION 4DCT allows accurate, in vivo syndesmotic measurements, which change with ankle ROM, confirming prior work that was limited to biomechanical studies. Side-to-side syndesmotic measurements are consistent within subjects, validating the method of templating syndesmotic reduction off the contralateral ankle, in a consistent ankle position, to achieve anatomic reduction of syndesmotic injury. LEVEL OF EVIDENCE Level II, prospective cohort study.

Abstract
PURPOSE Multiple Level I meta-analyses were conducted comparing traditional static vs. more recently introduced dynamic strategies of fixation for injuries of the distal tibiofibular syndesmosis (TFS). The aim of this review was to assess their robustness and methodological quality, providing support in the choice of a treatment strategy in case of TFS injury using the highest level of evidence. METHODS In this systematic review, conducted in accordance with the PRISMA guidelines, meta-analyses/systematic reviews comparing static and dynamic fixation methods after acute TFS injury were identified. The robustness of studies was evaluated using the fragility index (FI) for meta-analysis and the fragility quotient (FQ). The risk of bias was evaluated using the Assessment of Multiple Systematic Reviews (AMSTAR) instrument. Finally, the Jadad was applied to select the study which provided the highest quality of evidence to develop recommendations for the fixation strategy of these lesions. RESULTS Out of 1.302 records, four Level I meta-analyses were included in this study. Analyzing the statistically significant dichotomous outcomes, the median FI was 3.5 (IQR, 2 to 5.5; range, 1 to 9), while the median FQ was 1.9% (IQR, 1 to 3.5; range 0.35 to 4.4). In total, 37% had an FI of 2 or less and 75% of outcomes had a FI of 4 or less. According to the AMSTAR score and Jadad algorithm, the largest meta-analysis was selected as the highest evidence provided so far. CONCLUSION The meta-analyses with statistically significant dichotomous outcomes comparing dynamic and static fixation for treating injuries of the distal tibiofibular syndesmosis are fragile, with a change in less than four patients or less than 2% of the study population sufficient to reverse a significant outcome to nonsignificant. LEVEL OF EVIDENCE Level I.

Abstract
BACKGROUND This study aimed to identify risk factors for chronic syndesmotic instability following syndesmotic fixation. METHODS We performed a retrospective review of consecutive patients who had sustained ankle fractures requiring syndesmotic fixation. Patients available for a minimum 5 years of follow-up were classified into 2 groups according to the presence of syndesmotic instability. Statistical binary logistic regression analyses were performed to investigate the significance of various risk factors. Functional outcomes were assessed using the FAOS. RESULTS In total, 166 patients who met the study inclusion criteria underwent analysis. The overall postoperative instability rate was 20.5%, which was significantly affected due to BMI (p = 0.018; OR 6.72), and concomitant posterior malleolar fracture (p = 0.032, OR 2.77). The mean scores in the syndesmotic instability (SI) group were significantly lower than those in the no syndesmotic instability (NSI) group (p = 0.021). CONCLUSIONS Obesity and concomitant posterior malleolar fracture were significant risk factors for postoperative syndesmotic instability.

Abstract
OBJECTIVE Randomised controlled trials (RCT) with short-term follow-ups have shown that, in treatment of syndesmosis injuries, a suture button device (SB) resulted in better radiographic and functional outcome compared to syndesmosis screw fixation (SS). However, only one RCT has reported long-term results; thus, the syndesmosis malreduction rates for both implants might increase during longer follow-up. The primary objective of this RCT was to evaluate the maintenance of syndesmosis reduction with the SS compared to the SB fixation in patients during a minimum follow-up of 6-years. The secondary objectives were to assess the post-traumatic osteoarthritis (OA) grade and the functional outcome. PATIENTS AND METHODS At Oulu University Hospital, between January 2010 and December 2011, we enrolled 43 patients with Lauge-Hansen pronation-external rotation type 4/Weber C, ankle fractures with unstable syndesmosis. Patients were randomised to treatment with either a single 3.5-mm tricortical SS (22 patients) or an SB (21 patients). The mean follow-up was 7.1 years (range, 6.2-7.9). Syndesmosis reduction and OA grade was assessed with standing cone-beam computed tomography (CBCT) of both ankles. Malreduction was defined as >2 mm side-to-side difference in the mean width of the syndesmosis. OA was graded according to the Morrey & Wiedeman classification. The Olerud-Molander Ankle Outcome Score (OMAS) and a quality of life questionnaire (RAND 36-Item Health Survey) were used to evaluate functional outcome. RESULTS Two syndesmoses in the SS group and one in the SB group were malreduced (P = 0.58). Moderate OA after a mean of 7 years post-injury was common. In the SS and SB groups, 9 of 16 and 11 of 13 patients, respectively, had one or more grades serious OA in the injured ankle than in the uninjured ankle (P = 0.11). The mean OMAS was 88 in the SS group and 78 in the SB group (difference between means 7.1, 95% CI: -7.0-21.1, P = 0.32). The RAND-36 results did not differ between groups. CONCLUSION The SS and SB maintained syndesmosis reduction equally well during follow-up. Our study findings also suggest that both methods result in moderate OA rates and the functional outcome is comparable between these two syndesmosis fixation methods.

Abstract
BACKGROUND Adequate reduction and stabilization of the syndesmosis are significant to prevent early degeneration of the ankle joint and get better clinical outcomes. However, the routine surgical methods have diffierent limitations. The purpose of this study was to develop a novel double Endobutton fixation to treat the distal tibiofibular syndesmotic injuries, and determine whether the novel double Endobutton fixation demonstrates a better biomechanical property compare with the intact syndesmosis, the screw fixation and the Tightrope fixation. METHODS Twenty-four normal fresh-frozen ankle specimens with a mean age of 42 ± 8 (range, 28-62) years were randomly divided equally into four groups: (1) the intact group, (2) the screw group, (3) the Tightrope group, (4) the Endobutton group. 3D printer technology was used to establish the personalized distal tibiofibular syndesmotic navigation modules to determine the accurate bone tunnel. Axial loading was applied in five ankle positions: neutral position, dorsiflexion, plantar flexion, varus and valgus. Rotation torque was applied in two ankle rotation of the neutral position: internal and external. RESULTS In most situations, the displacements of the intact group were larger than the screw group, the Tightrope group and the Endobutton group (P < .05), and the displacements of the screw group were smaller than other three groups (P < .05). The displacements of the double Endobutton group were slightly larger than the Tightrope group but no significant differences were found between these two groups except in the dorsiflexion position of axial loading experiments (P < .05). The novel double Endobutton fixation was steadier than intact syndesmosis and more micromotional than screw fixation. CONCLUSION Our study demonstrated that the novel double Endobutton can be considered as the better fixation in treatment of distal tibiofibular syndesmotic injuries. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
Background: Our aim was to compare the outcome between suture button (SB) stabilization and syndesmotic screw fixation (SF) in patients with acute syndesmotic diastasis. Methods: A systematic literature search up to June 30, 2021, was performed to identify randomized controlled trials (RCTs) comparing outcomes of SB with SF techniques in patients with acute syndesmotic diastasis. We calculated mean differences for continuous outcomes, using the Hartung-Knapp-Sidik-Jonkman method, and odds ratio for dichotomous outcomes, using the Mantel-Haenszel method. Results: Eight RCTs involving 569 patients met the inclusion criteria, 1 RCT with level I evidence, and 7 RCTs with level II evidence. The meta-analysis showed that the SB technique had a higher AOFAS score <6 months and 12 months postoperatively (MD = 4.74, 95% CI 1.68-7.80, P = .01; and MD = 5.42, 95% CI 1.50-9.33, P = .02) and reduced the risk of implant irritation (OR = 0.31, 95% CI 0.11-0.89, P = .03), implant failure (OR = 0.06, 95% CI 0.02-0.23, P < .01), and reoperation (OR = 0.43, 95% CI 0.22-0.83, P = .01). The 2 approaches did not differ in further functional outcomes or postoperative complications. Conclusion: Because functional outcomes showed no relevant difference between both SB and SF, the advantage of SB appears to be in the lower risk for postoperative complications. The SB technique led to fewer cases of implant irritation, implant failure, and reoperation compared with SF. Level of Evidence: Level I, meta-analysis of RCTs.
