中文摘要：
全髋置换中，假体自身设计参数及安装参数将直接影响术后假体的活动范围。术前了解不同参数下髋关节假体的理论活动度，可以帮助临床医生选取满足正常活动需求的最佳假体及相应的安装参数值。基于此目的，参数化模拟人工全髋关节三维运动的可狈化仿真模块被成．功建立，通过设定人工髋关节不同的设计参数和假体安装参数，在视觉和数值上模拟了相应参数下关节的外展／内收、屈曲／后伸、外旋，内旋运动，并通过检测假体间的碰撞来确定关节理论活动度。
英文摘要：
Prosthesis＇ design parameters and fixing parameters will directly affect the prosthesis＇ range of motion after total hip arthroplasty. To know the theoretical range of motion of hip joint prosthesis in different parameters can help surgeon select suitable prosthesis and fixing parameters to meet the requirement of normal activities. For this purpose, a visual simulation module was successfully established. Different design and fixing parameters of artificial hip joint can be set, and the abduction / adduction, flexion / extension, external rotation / internal rotation under the corresponding parameters can be simulated. The theoretical range of motion of hip joint prosthesis was determined by a sensor which can detect the collision between prostheses.
