研究了髋关节在负重下静立、慢行、疾走的力学特征。通过医学影像控制系统Mimics和工程软件Solidworks的结合使用，完成从CT断层图像（DICOM格式）到在Mimics环境中进行三维模型重建、模型的修整光洁，再导入到工程软件UG中进行有限元分析的整个过程。由对髋关节的静力分析得出髋关节的应力分布和变形结果，为合理设计髋关节骨折手术和术后关节活动的早期康复计划提供重要的理论依据。%The mechanical characteristics of hip joint loading during quiet-standing,slow going and rushing are investigated.By combined application of medical imaging control system “Mimics”and engineering software“Solidworks”,from CT tomography image (DICOM form)to the 3 D model reconstruction repairing and clean-ing in the mimics environment,element analysis is finally done after importing it to the engineering software UG.The results of the hip stress distribution and deformation provide important theoretical basis for reasonable designing of hip fracture surgery and the early rehabilitation program of postoperation.
