中文摘要：

以髋关节置换术后常见的脱位失效为研究对象，在Adams运动学分析软件环境下，设计并开发了可视化髋关节假体运动分析模块．该模块能够构建不同设计参数的髋关节假体模型，模拟各种行为条件下的髋关节运动，检测关节假体的活动范围．利用光学运动捕捉系统对正常人群进行日常行为的下肢运动学测量．将模块对假体的运动学分析结果与实验测量的天然关节的运动数据对比，研究并发现了髋关节假体的脱位与行为运动的关系，结果显示术后的高屈曲动作脱位风险较大，尤其是下蹲动作．

英文摘要：

Taking the common dislocation failure after total hip arthroplasty as research object, the visual motion analysis module of hip prosthesis based on Adams was designed and developed. This module can construct the hip prosthesis model with different design parameters, simulate motions for various behavior condition, and acquire motion range of hip prosthesis. The kinematics data of the lower limbs during action of daily living was obtained by using the optical motion capture system. Comparing the theoretical motion data obtained by module and the experimental kinematics data of the natural joint, this paper studied the relationship between the dislocation of the hip prosthesis and the action of daily living. The results unveil that it is of high risk performing high flexion activities, especially squatting activity. The research results would be helpful for clinical rehabilitation, prosthesis design and optimization.
