We report our experience with the Minimally Invasive Chevron Akin (MICA) technique for correcting hallux valgus, and evaluate its effectiveness and associated complications.
Case series of 13 feet with mild to moderate symptomatic hallux valgus treated surgically from July 2013 to December 2014, with at least 48-months follow-up. Patients were assessed pre-operatively and post-operatively with radiographical measurements (Hallux Valgus Angle (HVA) and Intermetatarsal Angle (IMA)) and clinical scores (American Orthopaedic Foot and Ankle Society (AOFAS), 36-Item Short Form Health Survery (SF-36), Visual Analog Scale (VAS)).
Mean HVA and IMA decreased from 30.4° and 13.9°-10.9° and 10.2° respectively (p<0.05). The mean AOFAS score improved from an average of 59.0-93.7 (p<0.05). All patients reported a VAS score of 0 post-operatively, and the 4 SF-36 domains improved significantly (p<0.05).
The MICA technique is a safe and effective method in the surgical correction of mild to moderate hallux valgus deformity, and continued use is justified.
我们报告了采用微创V形截骨联合Akin截骨术（MICA）矫正拇外翻的经验，并评估其有效性及相关并发症。
对2013年7月至2014年12月期间手术治疗的13例轻至中度症状性拇外翻患者进行病例系列研究，随访至少48个月。术前和术后对患者进行影像学测量（拇外翻角（HVA）和跖间角（IMA））及临床评分（美国矫形足踝协会（AOFAS）评分、36项简明健康调查问卷（SF-36）、视觉模拟量表（VAS））。
平均HVA和IMA分别从30.4°和13.9°降至10.9°和10.2°（p<0.05）。平均AOFAS评分从59.0提高到93.7（p<0.05）。所有患者术后VAS评分为0，且SF-36的4个维度均有显著改善（p<0.05）。
MICA技术是手术矫正轻至中度拇外翻畸形的一种安全有效的方法，值得继续应用。
