【摘要】 目的：探讨外翻的病因、发病机制，指导手术治疗。方法：选取６３足前后位Ｘ线片，其中，正常人３７足，外翻病人２６足，测量并统计分析以下参数：ＭＰＪＣ、ＭＰＡＤ、ＤＡＳＡ、ＰＡＳＡ、ＨＡＡ、ＩＭＡ。结果：外翻病人有明显的ＭＰＪＣ、ＭＰＡＤ、ＰＡＳＡ增大。ＨＡＡ、ＩＭＡ、ＰＡＳＡ之间并不存在统计学上的联系。结论：外翻的病理可以分为３型：Ⅰ型，ＩＭＡ增大为主型；Ⅱ型，ＰＡＳＡ增大为主型；Ⅲ型，混合型。Ⅰ型宜采用矫正ＩＭＡ的术式；Ⅱ型宜采用矫正ＰＡＳＡ的术式，不宜采用矫正ＩＭＡ的术式；Ⅲ型应联合应用以上２种术式。更多还原

【Abstract】 Objective:To study the physiology and surgical treatment of hallux abductus valgus.Methods:63 feet X ray films are measured,26 feet of which have hallux abducts valgus.MPJC,MPAD,DASA,PASA,HAA,IMA are for statistical analysis.Results:Hallux abducts valgus has larger MPJC,MPAD,PASA,HAA,IMA and PASA have no statistical relation.Conclusions:Hallux abductus valgus is classified into three types:Ⅰ type,IMA enlarge dominant;Ⅱ type,PASA enlarge dominant;Ⅲ type,mixed.To correct IMA procedure is suitable for Ⅰ type,while to correct PASA procedure,not to correct IMA procedure,is for Ⅱ type,Ⅲ type is treated by these two procedures combined.更多还原
