ARTICLE HIGHLIGHTS
Research background

Several minimally invasive surgical techniques for the correction of hallux valgus (HV) have emerged in the literature. These techniques concern the distal osteotomy of the first metatarsal, the use or not of internal fixation, osteotomy of the base of the first phalanx (Akin osteotomy). All these techniques can be associated with the lateral release of soft tissues.

Research motivation

The lack of copious prospective studies regarding lateral soft tissues release (LSTR) procedure.

Research objectives

The object of this study is to evaluate the role of LSTR on percutaneous HV correction, evaluating functional and radiographical results.

Research methods

From January 2012 to May 2016, a total of 396 patients with mild to moderate symptomatic HV treated with the MIS technique were included in this retrospective study. The technique provides no internal fixation. Patients were divided into the LSTR group (LSTR Y) and no LSTR group (LSTR N). This surgical procedure (LSTR) was reserved for insufficient HV angle (HVA) correction during fluoroscopic control. Patients were evaluated at each follow-up by two other authors after appropriate training by senior authors (first practitioners).

Research results

We found a statistically significant difference in range of motion between the two groups (LSTR-N and LSTR-Y) at 6 mo (P = 0.018423) and the last follow-up (P = 0.02). There are no significant differences between groups for the other parameters assessed (HVA, intermetatarsal angle, American Orthopaedic Foot and Ankle Society, visual analog scale).

Research conclusions

LSTR does not seem to affect pathology relapse, while the adequate correction of HVA remains the crucial factor. LSTR seems to increase postoperative joint stiffness with a comparable incidence of relapse and a low incidence of complications.

Research perspectives

Because of the lack of copious prospective studies regarding LSTR procedure, we feel a more thorough literature review is presented with both prospective and retrospective analyses. The results of this study should be useful to surgeons treating this condition and can be used in the design of future investigations into the joint stiffness.
