Recurrence of hallux valgus (HV) is a common complication after forefoot surgery for rheumatoid forefoot deformities. The aim of this study is to evaluate the impact of hindfoot malalignment on recurrence.
This was a retrospective observational study designed to analyze the radiographic outcomes of 87 feet in 64 patients with rheumatoid arthritis treated with a joint-preserving surgery for HV deformity. Differences in hindfoot alignment preoperatively between the recurrence and nonrecurrence groups was compared.
There were no significant differences in hindfoot alignment preoperatively between groups. To estimate the impact of technical problems, the HV and intermetatarsal angles measured from radiographs 3 months postoperatively were compared between groups. The HV angles in the recurrence group were significantly larger than those in the nonrecurrence group (p=0.02).
There were no significant differences between preoperative hindfoot malalignment and postoperative recurrence of HV in rheumatoid forefoot surgeries.
拇外翻（HV）复发是类风湿性前足畸形前足手术后常见的并发症。本研究的目的是评估后足排列不齐对复发的影响。
这是一项回顾性观察研究，旨在分析64例类风湿性关节炎患者的87只脚接受保留关节手术治疗HV畸形后的影像学结果。比较复发组和非复发组术前的后足排列差异。
两组术前的后足排列无显著差异。为评估技术问题的影响，比较了两组术后3个月X线片测量的HV和跖间角。复发组的HV角明显大于非复发组（p=0.02）。
类风湿性前足手术中，术前的后足排列不齐与术后HV复发之间无显著差异。
