摘要：

背景：对于踝关节的生物力学的研究日益成为热点，也从以往传统的生物力学已发展到有限元力学分析。
目的：建立踝关节的三维有限元数字模型，探讨踝关节各组成部分的应力分布规律。
方法：对一名成年女子行踝关节螺旋CT扫描，将所得图像经Mimics、Geomagic处理，得到三维有限元数字模型。
结果与结论：建成了包括胫腓骨下段、距骨的三维有限元数字模型。该模型外形逼真，几何相似性好，可以随意旋转，方便从多角度观察模型，采集三维信息，适合进行生物力学研究。

Abstract:

BACKGROUND: Biomechanics research of ankle joint increasingly becomes a hot spot. Research method in previous studies is traditional biomechanical research that has developed to finite element mechanical analysis
OBJECTIVE: To establish a three-dimensional finite element digital model of ankle joint and to discuss the stress distribution of various components in the ankle joint.
METHODS: An adult woman was selected to treat with spiral CT scanning on ankle. The obtained images were processed by Mimics and Geomagic for the establishment of three-dimensional finite element digital model.
RESULTS AND CONCLUSION: The three-dimensional finite element digital model was established, including distal tibiofibular shaft and talus. With realistic appearance and excellent geometry-comparability, the rotatable model of ankle is available to be observed from different perspectives, to be collected three-dimensional data and is valid for biomechanical study.
