Abstract

The purpose of this study was to evaluate the radiographic outcomes of distal chevron metatarsal osteotomy associated with lateral joint capsule split as only lateral soft tissue release in patients with symptomatic moderate and severe hallux valgus (HV) deformity. Ninety patients (103 feet) at our institution between January 2014 and December 2019 were included in the present retrospective study. Each patient was evaluated preoperatively and at final follow-up by means of weight bearing radiographs lateral and dorsoplantar views. We analyzed hallux valgus angle (HVA), first-second intermetatarsal angle (IMA) and medial sesamoid position (MSP). The mean follow-up time was 21.8 months (range 6-69.4). The mean of the HVA improved, from 36.6 to 24.3º, the IMA from 13.05 to 9.93º and the MSP from 2 to 1. Our study demonstrates that the deformity recurrence rate after surgery is 69.9%. Radiologic HV recurrence was defined by a final HVA equal or more than 20 degrees at final follow-up. Level of Evidence, IV.

中、重度拇外翻侧边软组织松解联合远端跖骨截骨术。

本研究的目的是评估有症状的中度和重度拇外翻（HV）畸形患者的远端跖骨截骨术伴外侧关节囊分裂作为仅外侧软组织释放的影像学结果。2014年1月至2019年12月期间，我们机构的90名患者（103英尺）被纳入本回顾性研究。每位患者术前和最终随访时均通过负重x线片侧位和足底背位进行评估。我们分析了拇外翻角（HVA）、第一-第二跖间角（IMA）和正中籽骨位置（MSP）。平均随访时间21.8个月（范围6 ~ 69.4）。HVA平均值由36.6º提高到24.3º，IMA由13.05º提高到9.93º，MSP由2º提高到1º。我们的研究表明，术后畸形复发率为69.9%。放射学上的HV复发定义为最终随访时HVA等于或大于20度。证据水平，IV。
