摘　　要：目的为研制国人胫骨远端后内侧解剖型钢板提供解剖学依据。方法将40例成人活体胫骨进行螺旋CT扫描并重建三维图像,测量胫骨远端后内侧后翻角度、扭转高度、置钉安全区高度等解剖学指标并与整体信息作相关分析。结果胫骨远端后内侧后翻角度由外向内逐渐增大,而扭转高度由外向内则逐渐降低。胫骨远端后内侧后翻角度与身高、性别及年龄无显著性相关,胫骨远端后内侧置钉安全区高度、扭转高度与身高有正向直线相关,与性别、年龄无显著性相关。结论胫骨远端后内侧解剖学指标及测量的数据对国人胫骨远端后内侧解剖型钢板的设计和临床应用具有重要的解剖学指导意义。Objective Toofferanatomicbasisfordesigninganatomicalplateofposteromedialpartofthe distal tibia. Methods 40 cases of healthy adults were scanned by spiral CT,and then three-dimensional reconstruction of tibia was performed. Anatomy characteristics of posteromedial distal tibia,including the postero-version angle of distal tibia,the twist height in the sagittal plane and the height of security zone for the screw in the distal tibia cross-section,were measured. Results The postero-version angle increased gradually,whereas,the twist height decreased,from the lateral to medial. Correlation analysis showed that the postero-version angle had no correlation with the length of tibia,gender and age,however,the height of security zone and the twist height appeared positive correlation with the length of tibia,despite of gender and age. Conclusions The anatomical characteristics of posteromedial distal tibia are valuable for guiding the development of posteromedial anatomical plate of distal tibial and its clinical application.
