This study aimed to detect the effect of a modified chevron osteotomy on hallux valgus (HV) deformity at five-year follow up.
Twenty patients with symptomatic HV who underwent modified chevron osteotomy between June 2014 and January 2016 were included in the present study. The minimum follow-up duration was five years. Each patient was evaluated preoperatively, six weeks postoperatively and five years postoperatively using the visual analog scale (VAS) pain score, the American Orthopedic Foot & Ankle Society (AOFAS) score and cosmetic and radiological outcomes.
The AOFAS score improved from 54.40 ( ± 4.58) preoperatively to 94.30 ( ± 2.15) six weeks postoperatively (p < 0.001) and 96.95 ( ± 1.54) five years postoperatively (p < 0.001). The VAS scores decreased from 6.30 ( ± 1.17) preoperatively to 0.15 ( ± 0.37) five years postoperatively (p < 0.001). The mean intermetatarsal angle improved from 16.00° ( ± 2.20°) preoperatively to 4.15° ( ± 1.22°) six weeks postoperatively (p < 0.001) and 4.40° ( ± 1.39°) five years postoperatively (p < 0.001). The mean HV angle also improved, from 32.70° ( ± 5.34°) preoperatively to 4.80° ( ± 1.40°) six weeks postoperatively (p < 0.001) and 5.20° ( ± 1.32°) five years postoperatively (p < 0.001). The cosmetic results were either excellent or good in 19 patients (95%). There was no recurrence in this study during the five postoperative years.
A modified chevron osteotomy can achieve successful correction of moderate-to-severe HV, with excellent outcomes at five-year follow up.
本研究旨在探讨改良 Chevron 截骨术治疗拇外翻（HV）畸形的 5 年随访效果。
本研究纳入了 2014 年 6 月至 2016 年 1 月期间接受改良 Chevron 截骨术的 20 例有症状的 HV 患者。本研究的最小随访时间为 5 年。每位患者在术前、术后 6 周和术后 5 年分别采用视觉模拟评分（VAS）疼痛评分、美国矫形足踝协会（AOFAS）评分以及美容和影像学结果进行评估。
AOFAS 评分从术前的 54.40（±4.58）分提高到术后 6 周的 94.30（±2.15）分（p＜0.001）和术后 5 年的 96.95（±1.54）分（p＜0.001）。VAS 评分从术前的 6.30（±1.17）分降至术后 5 年的 0.15（±0.37）分（p＜0.001）。跖骨间角从术前的 16.00°（±2.20°）改善至术后 6 周的 4.15°（±1.22°）（p＜0.001）和术后 5 年的 4.40°（±1.39°）（p＜0.001）。拇外翻角也从术前的 32.70°（±5.34°）改善至术后 6 周的 4.80°（±1.40°）（p＜0.001）和术后 5 年的 5.20°（±1.32°）（p＜0.001）。19 例（95%）患者的美容效果为优秀或良好。在术后 5 年的随访中，没有复发的病例。
改良 Chevron 截骨术可成功矫正中重度 HV，5 年随访结果良好。
