RESULTING DISPLACEMENT OF DIFFERENT COMPONENTS OF CERAVEROSTEAL HIP PROSTHESIS FOR THE DIFFERENT DAILY ACTIVITIES OF A PATIENT

Abstract

Finite element analysis has been used extensively in the study of bone loading and implant performance, such as in the femur. The boundary conditions applied vary widely, generally producing excessive femoral deformation, and although the muscle forces influence femoral deflections and loading, little consideration has been given to the displacement constraints. In our study, which is a dynamic study of this PTH, one drew corresponding displacements from each activity of the patient for each link of the structure, and their consequences on the stability and the risk loosening of implant, by making a comparative interpretation for each component of the PTH which is (Cement; Cortical bone and Implant).In this study deals with the corresponding maximum displacements for each component of the structure.
