Abstract: To seek the individual design of implant and enlarged implant, the adaptive bone model is constructed for total hip replacement and the correspording static analysis is carried out to provide a precondition for the replacement. Reverse engineering and three-dimensional finite-element analysis are used to model and investigate the loaded femur in static state with ANSYS V6.1, it is revealed that the obviously stressed region arises near the lateral femur conne ction with the inosculated implant in the cavity. The proposed model is expected to apply to hip replacement and repairs, especially for Chinese.
