ABSTRACT To identify complications that necessitated revision surgery after the primary operation, a multicenter retrospective chart review was conducted for 646 patients who received either a modified chevron-Austin osteotomy (270 patients), modified Lapidus arthrodesis (342 patients), or closing base wedge osteotomy (34 patients) to correct hallux valgus deformity. Revision surgery for complications was calculated and compared. All surgery was performed by 1 of 5 staff foot and ankle surgeons at Kaiser Permanente medical centers. Complications included recurrent hallux valgus, iatrogenic hallux varus, painful retained hardware, nonunion, postoperative infection, and capital fragment dislocation. The rates of revision surgery after Lapidus arthrodesis, closing base wedge osteotomy and chevron-Austin osteotomy were similar with no statistical difference between them. The total rate for re-operation was 5.56% among patients who received chevron-Austin osteotomy, 8.82% among those who had a closing base wedge osteotomy, and 8.19% for patients who received modified Lapidus arthrodesis. Among patients who had the chevron-Austin osteotomy procedure, rates of re-operation were 1.85% for recurrent hallux valgus and 1.48% for hallux varus. Among patients who had the modified Lapidus arthrodesis, rates of re-operation were 2.92% for recurrent hallux valgus and 0.29% for hallux varus. Among patients who had the closing base wedge osteotomy, rates of reoperation were 2.94% for recurrent hallux valgus and 2.94% for hallux varus. The collected comparative complication rates should serve to provide adjunctive information for foot and ankle surgeons and patients regarding hallux valgus surgery.

    ABSTRACT: KEYWORD � Severe hallux valgus � Distal metatarsal osteotomy � Chevron � Correction power � Intramedullar plate � Novel technique KEY POINTS Q6 � The concept of minor and moderate deformities being treated by distal osteotomies and the severe deformities treated best by proximal metatarsal osteotomies is changing. � High, powerful correction for aggressive distal chevron osteotomy can be fixed by a stable intramedullar plate. � A new technique of fixation is based on the Murawski and Beskin concept, because a powerful correction can be performed with a minimally invasive approach. � A low rate of complications is due to minimal invasive technique.

    ABSTRACT: Hallux valgus with or without first ray insufficiency has been strongly implicated as a contributing factor in lesser metatarsal overload. The principle goals of a bunionectomy are to relieve the pain, correct the deformity, and restore first metatarsophalangeal joint congruity. Until now, little evidence has been available to assess the effects of bunionectomy procedures on forefoot pressure. The primary aim of the present prospective study was to evaluate the preoperative and postoperative plantar pressures after 2 specific bunionectomies: the chevron bunionectomy and Lapidus arthrodesis. A total of 68 subjects, 34 in each group, were included for radiographic and pedographic evaluation. Both procedures demonstrated radiographic improvements in the mean intermetatarsal and hallux abductus angles. The mean hallux plantar pressure decreased significantly in both procedure groups (p < .001). However, Lapidus group exhibited an increase in the mean fifth metatarsal head plantar pressure (p = .008) and pressure under the fifth metatarsal as a percentage of the total forefoot pressure (p = .01). Furthermore, the pressure under the second metatarsal as a percentage of the total forefoot pressure decreased significantly (p = .01). This study suggests that the Lapidus arthrodesis and chevron bunionectomy both provide correction for hallux valgus deformity, but when comparing forefoot load sharing pressures, the Lapidus arthrodesis appeared to have greater influence on the load sharing distribution of forefoot pressure than did the bunionectomy employing the chevron osteotomy.

    ABSTRACT: Recurrence of hallux valgus deformity can be a common complication after corrective surgery. The cause of recurrent hallux valgus is usually multifactorial, and includes patient-related factors such as preoperative anatomic predisposition, medical comorbidities, compliance with postcorrection instructions, and surgical factors such as choice of the appropriate procedure and technical competency. For a successful outcome, this cause must be ascertained preoperatively. Although the algorithm to determine which intervention should be used is not unlike that of primary hallux valgus surgery, operative correction of hallux valgus recurrence can be challenging. This article discusses these challenges, complications, causes, and techniques.
