There are many types of treatments for calcaneal fractures, including conservative treatment, conventional surgical treatment, and minimally invasive surgery. The choice of specific treatment options is still controversial. Open reduction and internal fixation are currently the most commonly used surgical procedures in the clinic. A good fracture reduction effect can be achieved by using the lateral extension incision of the calcaneus; however, many studies have reported a high incidence of postoperative incision complications. Although there are many methods for the classification of intra-articular calcaneal fractures, it is generally believed that the computed tomography (CT) classification proposed by Sanders has high application value in the selection of treatment methods and evaluation of prognosis of calcaneal fractures. However, this method has no clear guiding significance for the choice of surgical incision and surgical plan.
To explore the application and clinical efficacy of medial column classification in the treatment of intra-articular calcaneal fractures.
From July 2017 to July 2018, 91 patients, including 60 males and 31 females aged 27 to 60 years, were enrolled. All participants had closed intra-articular calcaneal fracture, and their surgical options were selected under the guidance of medial column classification. The patients’ fractures were classified according to the Sanders classification: Type II, 35 cases; Type III, 33 cases; and Type IV, 23 cases. Among them, 53 patients had medial column displacement (shortened varus) and underwent open reduction and internal fixation with L-lateral incision of the calcaneus; 38 patients had no displacement of the medial column and underwent open reduction and internal fixation with tarsal sinus incision. The calcaneus Böhler angle, Gissane angle, length, width, height, and step thickness of the articular surface were evaluated by X-ray and three-dimensional CT before and after surgery and at the last follow-up. Foot function recovery was assessed by the Maryland foot scoring criteria.
All patients were followed for 5 to 14 mo, with an average of 10.5 ± 2.9 mo. The fractures of all patients healed, and the healing time was 10 to 19 wk, with an average of 10.8 ± 1.5 wk. One patient developed wound infection 1 wk after surgery and was actively debrided and implanted with antibiotic calcium sulfate to control the infection. The patient's fracture healed 5 mo after surgery. One patient developed a sural nerve injury, and the symptoms disappeared 3 mo after surgery. The patients were assessed according to the Maryland foot scoring system: Excellent in 77 cases, good in 10, and fair in 4. The excellent and good rate was 95.6%.
Medial column classification can effectively guide the surgical selection for intra-articular fractures of the calcaneus.
Core Tip: This is a retrospective study to evaluate the application and clinical efficacy of medial column classification in the treatment of intra-articular calcaneal fractures. A total of 91 participants were selected under the guidance of medial column classification: 53 patients had medial column displacement and underwent open reduction and internal fixation with L-lateral incision of the calcaneus; 38 patients had no displacement of the medial column and underwent open reduction and internal fixation with tarsal sinus incision. According to the Maryland foot scoring system, the excellent and good rate was 95.6%. Medial column classification can effectively guide the surgical selection for intra-articular fractures of the calcaneus.
