To explore early efficacy of minimally invasive Chevron Akin(MICA) osteotomy for the treatment of mild to moderate hallux valgus.
From June 2019 to April 2021, a total of 26 patients (29 feet) with mild to moderate hallux valgus, including 1 male and 25 females aged from 19 to 78 years old with an average of(38.3±19.5) years old, were treated with MICA. Preoperative and postoperative hallux valgus angle(HVA), intermetatarsal angle(IMA) and shortening of the first metatarsal were observed and compared. American Orthopedic Foot and Ankle Society (AOFAS) forefoot scoring system and visual analogue scale (VAS) were applied to evaluate clinical outcome at the final follow-up, and complications were also recorded.
All patients obtained followed up from 12 to 33 months with an average of(19.6±5.1) months. HVA and IMA was improved from (32.3±6.6)° and (11.7±3.2)° pre-operatively to (13.0±5.3)° and (6.1±3.2)° post-operatively, respectively, which had a significant difference (<0.01). The average shortening of the first metatarsal was (2.7±1.1) mm. AOFAS and VAS was improved from (55.7±7.4) and (6.5±1.5) preoperatively and to (88.5±7.9) and (0.7±0.4) respectively at the final follow-up, which also had a significant difference(<0.01). According to AOFAS score, 15 feet achieved an excellent result, 11 good and 3 moderate.
MICA osteotomy is a safe and reliable surgical technique for mild to moderate hallux valgus with advantages of minimally invasive, rapid recovery, low complication rate and an effect improvement of hallux valgus deformity.
探讨微创Chevron Akin（MICA）截骨术治疗轻中度拇外翻的早期疗效。
2019年6月至2021年4月，共26例（29足）轻中度拇外翻患者接受MICA治疗，其中男性1例，女性25例，年龄19～78岁，平均（38.3±19.5）岁。观察并比较术前和术后拇外翻角（HVA）、第1跖骨间角（IMA）及第1跖骨短缩情况。末次随访时应用美国矫形足踝协会（AOFAS）前足评分系统和视觉模拟评分法（VAS）评估临床疗效，并记录并发症。
所有患者均获随访，随访时间12～33个月，平均（19.6±5.1）个月。HVA由术前（32.3±6.6）°改善至术后（13.0±5.3）°，IMA由术前（11.7±3.2）°改善至术后（6.1±3.2）°，差异均有统计学意义（<0.01）。第1跖骨平均短缩（2.7±1.1）mm。末次随访时AOFAS评分和VAS评分分别由术前（55.7±7.4）和（6.5±1.5）改善至（88.5±7.9）和（0.7±0.4），差异也有统计学意义（<0.01）。根据AOFAS评分，优15足，良11足，可3足。
MICA截骨术治疗轻中度拇外翻安全可靠，具有微创、恢复快、并发症少及拇外翻畸形改善明显等优点。
