This is a retrospective study of 10 patients (13 feet) with moderate to severe hallux valgus who underwent a chevron or modified chevron osteotomy with multiple adjunctive soft-tissue releases for surgical treatment. Radiographic and subjective results were evaluated with an average follow-up of 24 months (range, 10-41). Preoperative criteria included an intermetatarsal (IM) angle of greater than 16 degrees (average of 18.4 degrees) and painful hallux valgus deformity. Average preop hallux abductus was 35.4 degrees (range, 25 degrees-48 degrees). The average reduction in the actual IM angle was (-) 5.2 degrees with a relative IM correction of (-) 11.6 degrees. Average postoperative hallux abductus angle was 7.0 degrees (range, 0 degree-22 degrees). Subjectively, all patients were satisfied with their results and stated they would have the procedure again. No complications were noted in this patient population, including, infection, avascular necrosis, hallux varus, and recurrence of deformity. The chevron osteotomy was found to be successful in this population with high intermetatarsal angles when appropriate consideration was given to correction of soft-tissue-deforming forces and contractures.
这是一项对10例（13足）中重度拇外翻患者进行的回顾性研究，这些患者接受了V形截骨术或改良V形截骨术，并辅以多种软组织松解术进行手术治疗。对影像学和主观结果进行了评估，平均随访24个月（范围10 - 41个月）。术前标准包括跖间（IM）角大于16度（平均18.4度）以及疼痛性拇外翻畸形。术前拇外展平均角度为35.4度（范围25度 - 48度）。实际IM角平均减小（-）5.2度，相对IM矫正为（-）11.6度。术后拇外展角平均为7.0度（范围0度 - 22度）。主观上，所有患者对其结果均满意，并表示愿意再次接受该手术。该患者群体未出现并发症，包括感染、缺血性坏死、拇内翻和畸形复发。当适当考虑矫正软组织变形力和挛缩时，发现V形截骨术对于该组高跖间角患者是成功的。
