Introduction Hallux valgus is one of the most common forefoot deformities worldwide. Females are affected more often than males. The three most common clinical symptoms are the painful bunion, transfer metatarsalgia, and hammer or claw toes. Methods This case series consisted of 20 patients who had chevron osteotomy from January 2015 to January 2016. The clinical assessment was measured by The American Orthopedic Foot and Ankle Score (AOFAS), and radiologic assessment was determined by preoperative and postoperative hallux valgus angle (HVA) and intermetatarsal angle (IMA). Results The patients' mean age was 56 years. Out of 20 patients, 19 were female, and one was male. The mean AOFAS improved from 51 preoperatively to 82 postoperatively. The HVA improved from 26° preoperatively to 14°. There were five complications including four Kirschner (K)-wire complications. Conclusion Distal chevron osteotomy is a reliable and time-tested procedure. The K-wire fixation has a relatively high complication rate. We planned to use other methods of fixation and then compared them with K-wires fixation results for future studies.
引言
拇外翻是全球最常见的前足畸形之一。女性比男性更易患病。最常见的三种临床症状是疼痛性拇囊炎、转移性跖骨痛以及锤状趾或爪形趾。
方法
本病例系列包括20例在2015年1月至2016年1月期间接受了人字形截骨术的患者。临床评估采用美国矫形足踝协会评分（AOFAS），放射学评估通过术前和术后的拇外翻角（HVA）以及跖间角（IMA）来确定。
结果
患者的平均年龄为56岁。20例患者中，19例为女性，1例为男性。AOFAS平均分从术前的51分提高到术后的82分。HVA从术前的26°改善到14°。共有5例并发症，其中包括4例克氏针相关并发症。
结论
远端人字形截骨术是一种可靠且经过时间检验的手术方法。克氏针固定的并发症发生率相对较高。我们计划在未来的研究中采用其他固定方法，并将其与克氏针固定的结果进行比较。
