切开复位内固定治疗后踝骨折的疗效分析

目的评价切开复位内固定治疗后踝骨折的手术方法及临床疗效。方法回顾分析2005年6月-2008年12月,46例采用切开复位内固定治疗并获完整随访的涉及后踝骨折的踝关节骨折患者临床资料。男29例,女17例;年龄19～76岁,平均47.7岁。扭伤17例,摔伤15例,交通事故伤12例,其他伤2例。左踝25例,右踝21例。单纯后踝骨折6例,外踝及后踝骨折13例,三踝骨折22例,外踝及后踝骨折伴三角韧带损伤5例。伴内踝或外踝骨折者根据Lauge-Hansen分型标准:旋后外旋Ⅲ度13例,Ⅳ度9例;旋前外旋Ⅳ度18例。后踝骨折按照Naoki分型:后外侧斜型29例,内侧延伸型11例,小块撕脱骨折型6例。7例急诊手术,39例择期手术。结果术后2例出现切口浅表感染,经加强换药后切口愈合;其余患者切口均Ⅰ期愈合。46例均获随访,随访时间18～63个月,平均37个月。骨折均于术后3～6个月愈合,平均4.3个月。术后1个月1例出现腓肠外侧皮神经损伤症状,未作特殊处理;末次随访时9例负重或行走时出现踝关节疼痛不适,加强康复锻炼及止痛药物治疗。末次随访时根据美国矫形足踝协会(AOFAS)踝与后足评分标准进行功能评估,获优17例,良21例,中8例,优良率为83%。患者疼痛视觉模拟评分(VAS)为0～5分,平均1.9分。结论切开复位内固定治疗后踝骨折可获得较好疗效,但应根据骨折类型选择手术方式和固定方法。
