摘　　要：[目的]测量分析中国西南地区正常成年人踝关节X线片形态学参数,为新型国人全踝关节假体的设计提供参考。[方法]收集本院2014年5月-2015年8月行踝关节正、侧位X线片的正常成年人踝关节影像资料1 000例,随机抽取100例踝关节影像资料,其中重庆市67例,四川省26例,贵州省7例;男性50例,女性50例;右踝50例,左踝50例,年龄18-75岁[（38.40±12.41）岁],体重47-85 kg[（59.63±8.28）kg],身高154-185 cm[（165.35±7.45）cm]。运用PACS图文分析系统测量每例踝关节图像的踝穴前后距（APG）、踝穴宽度（Ti W）等13个踝关节形态参数。[结果]中国西南地区正常成年人踝关节形态学参数与意大利人相比,除胫骨宽度（Ti W）、踝穴前点与胫骨下段最厚处平面距离（MDA）、踝穴顶点与胫骨下段最厚处平面的距离（MDV）以及距骨关节面长宽比（Ta AL/Ta W）之外,滑车长度（Ta AL）、距骨宽度（Ta W）等9个踝关节形态参数差异具有统计学意义（P〈0.01）;与韩国人相比,踝穴弧长（Ti AL）、胫骨宽度（Ti W）等6个踝关节形态参数差异无统计学意义,而踝穴弧长（Ta AL）、距骨宽度（Ta W）等7个踝关节形态学参数差异具有统计学意义。中国西南地区男性与女性相比,除胫骨面长宽比（MTi Th/Ti W）、距骨面长宽比（Ta AL/Ta W）、踝部宽度与踝穴宽度比（Mal W/Ti W）之外,踝穴弧长（Ti AL）、踝穴宽度（Ti W）、距骨宽度（Ta W）等10个踝关节形态学参数差异具有统计学意义（P〈0.05）。[结论]（1）中国西南地区正常成年人踝关节形态参数与意大利人和韩国人存在差异,其中与意大利人差异较大,而接近于韩国人群;（2）中国西南人群踝关节形态学参数存在男性与女性之间的差异,且男性参数值均大于女性。[Objective] To measure and anlyze the plain X- ray film morphology parameters of the ankle in southwest China normal adults,in order to offer references to new type of Chinese total ankle joint prosthesis design. [Methods] Anteroposterior and lateral plain X- ray film of 1 000 cases of normal adults ankles from May 2014 to August 2015 were collected,100 cases of them,with 67 from Chongqing city,26 from Sichuan province,7 from Guizhou province,were randomly extracted. All examples included 50 cases of male,50 cases of female; 50 cases of right ankle,50 cases of left ankle. The patient ＇s age ranged from 18 to 75 years（ mean,38. 40 ± 12. 41 years old）,the body weight ranged from 47 to 85 kg（ mean,59. 63 ± 8. 28kg）,the body height ranged from 154 to185 cm（ mean,165. 35 ± 7. 45 cm）. PACS graphic analysis system was used to measure 13 ankle shape parameters including antero- posterior gap（ APG）,tibial width（ TiW） and so on. [Results] Compared with the parameters from Italians,nine ankle morphology parameters,besides tibial width（ TiW）,distance of level of MTiT h from the anterior limit of the mortise（ MDA）,distance of level of MTiT h from the vertex of the mortise（ MDV）,showed significantly statistical differences（ P〈0. 01）,including the aspect ratio of talus（ TaA L / TaW）,trochlea tali length（ TaA L）,tarsal width（ TaW）,etc. Compared with those from the Koreans,6 ankle morphology parameters,including tibial axc length（ TiA L）,the tibial width（ TiW）,etc,showed no statistical difference. While other 7 ankle morphology parame-ters,including the trochlea tali length（ TaA L）,the tarsal width（ TaW）,etc,were found statistical differences. Between male and female in southwest China population,the tibial aspect ratio（ MTiT h/TiW）,the aspect ratio of talus（ TaA L/TaW）,the width of the ankle and tibial width ratio（ MalW / TiW） showed nostatistical differences,while other 10 morphology parameters,including the trochlea tali length（ TaA L）,tibia
