  目的 探讨Austin手术治疗青少年踇外翻的临床疗效.方法 自2008年3月至2014年3月,采用Austin手术治疗轻中度青少年踇外翻病人9例17足,年龄16~19岁,平均17.6岁,术前、术后、及12个月随访时摄负重位X线片,测量踇外翻角(HVA),近端关节固定角(PASA),远端关节固定角(DASA),第一、二跖骨间角(IMA),术前、术后各组数据用t检验进行统计学处理分析.结果 9例患者全部获得随访,平均随访时间是15.6个月.未出现血管、神经损伤、感染等并发症,无内固定松动、断裂,踇外翻复发或第一跖骨头缺血坏死、转移性跖骨痛等并发症.术前HVA平均31.5°,术后为9.5°;术前IMA平均13.0°,术后为7.5°.采用美国足踝外科协会Maryland评分标准对疗效进行评定,优为90 ~ 100分共12足,良为80~89分4足,可70-79分1足,优良率为94.1%.结论 Austin手术具有良好的截骨稳定性,手术操作简单,并发症少,临床疗效满意,是治疗轻中度青少年踇外翻的理想术式之一.
