背景:[足母]外翻的手术治疗方式众多,传统Chevron有一定的手术操作局限性。目的:观察采用第1跖骨远端改良Chevron截骨治疗轻中度[足母]外翻的临床治疗效果。方法:2011年12月至2012年10月采用Chevron截骨对22例患者(28足)进行[足母]外翻矫正,记录患者术前、术后美国足踝外科医师协会评分(AOFAS),术前、术后测量第1、2跖骨间角(IMA)和躅外翻角(HVA)变化以评估矫正程度,采用AOFAS前足评分和生活功能评分简表(SF.36)评估功能恢复情况。结果:22名患者术后平均随访时间13.36个月(8~18个月),术前患者平均AOFAS评分(43.59±6.85)分,术后平均85.55±5.66分。术前患者平均SF.36量表评分(45.42±5.54)分,术后平均(83.23±8.81)分,两者术前、术后比较有显著统计学差异(P〈0.01)。IMA术前13.80°±1.67°,术后6.70°±1.51°(P〈0.01);HVA术前平均29.30°±2.78°,术后7.47°±2.82。(P〈0.01)。结论:第1跖骨远端改良Chevron截骨治疗轻中度蹰外翻手术操作技术简便,临床效果满意。
Background: There are many surgical treatments for hallux valgus. And traditaion Chevron osteotomy has some disadvan- tages during operative procedure. Objective: The purpose of the study is to evaluate the clinical results of mild to moderate hallux valgus with treatment of modified Chevron osteotomy of the first metatarsal head.. Methods: From December 2011 to October 2012, 22 patients (28 feet) were treated with modified Chevron osteotomy of the first metatarsal head for hallux valgus correction. The intermetatarsal angle (IMA) and hallux valgus angle (HVA) were re- corded to evaluate the correction before and after surgery. The American Orthopaedic Foot and Ankle Society (AOFAS) score and SF-36 (the Mos 36-item Short Form Health Survey) score were also recorded to evaluate fimction improvement. Results: The mean duration of postoperative follow-up for the 22 patients was 13.4 months (range, 8 to 18 months). Postop- erative AOFAS score and SF-36 scale were significantly higher than preoperative ones (43.59±6.85 vs 85.55±5.66, and 45.42±5.54 vs 83.23±8.81, P〈0.01). There were significant differences in IMA and HVA before and after the surgery (13.8°± 1.7° vs 6.7°±1.5°, 29.3°±2.8° vs 7.5±2.8°, P〈0.01). Conclusions: For the treatment of mild and moderate hallux valgus, the modified Chevron osteotomy of the first metatarsal head is simple and effective.
