چکیده

BACKGROUND The proximal medial opening wedge (PMOW) osteotomy has become more popular to treat moderate to severe hallux valgus with the recent development of specifically designed, low-profile modular plates. Despite the promising results previously reported in the literature, we have noted a high incidence of recurrence in patients treated with a PMOW. The purpose of this study was to report the clinical and radiographic outcomes of an initial cohort of patients treated with a PMOW osteotomy for moderate hallux valgus. METHODS We retrospectively analyzed prospectively gathered data on a cohort of 17 consecutive patients who were treated by the senior author using a PMOW osteotomy for moderate hallux valgus deformity. Average time to follow-up was 2.4 years (range, 1.0-3.5 years). The intermetatarsal angle (IMA), the hallux valgus angle (HVA), and the distal metatarsal articular angle (DMAA) were assessed on standard weightbearing radiographs of the foot preoperatively and at all follow-up visits. The Foot and Ankle Outcome Score (FAOS) was collected on all patients preoperatively and at final follow-up. RESULTS Despite demonstrating good correction of their deformity initially, 11 of the 17 patients (64.7%) had evidence of recurrence of their hallux valgus deformity at final follow-up. Patients who recurred had a greater preoperative HVA (P = .023) and DMAA (P = .049) than patients who maintained their correction. Improvement in the quality-of-life subscale of the FAOS was noted at final follow-up for all patients (P = .05). There was no significant improvement in any of the other FAOS subscales. CONCLUSIONS There was a high rate of recurrence of the hallux valgus deformity in this cohort of patients. Recurrence was associated with greater preoperative deformity and an increased preoperative DMAA. The PMOW without a concomitant distal metatarsal osteotomy may be best reserved for patients with mild hallux valgus deformity without an increased DMAA. LEVEL OF EVIDENCE Level IV, retrospective case series.

A Simple Method for Fixation of Proximal Opening-Wedge Osteotomy of the First Metatarsal for Correction of Hallux Valgus.

A simple, inexpensive technique for fixation of proximal opening-wedge osteotomy of the first metatarsal for correction of moderate or severe hallux valgus (HV) is described. After the opening-wedge osteotomy and bone grafting of the first metatarsal have been performed, 2 Kirschner wires are introduced for internal fixation and removed 8 weeks postoperatively. Twenty-three patients with sympto...

The Proximal Opening Wedge Osteotomy for the Correction of Hallux Valgus Deformity

Many surgical procedures exist to correct metatarsus primus varus associated with hallux valgus deformity. Among these procedures are various first metatarsal osteotomies. Both distal and proximal osteotomies have been described to correct these deformities with the latter typically used for the more severe deformity. The goal of the operative procedure is correction of the intermetatarsal and ...

Revisional Surgery for Hallux Valgus with Serial Osteotomies at Two Levels

The aetiology and form of hallux valgus (HV) is varied with many corrective procedures described. We report a 39-year-old woman, previously treated with a Chevron osteotomy, who presented with recurrent right HV, metatarsus primus varus, and associated bunion. Osteotomies were performed at two levels as a revisional procedure. This report highlights (1) limitations of the Chevron osteotomy and ...
