摘要：
Cemented and cementless hip prostheses are used in total hip replacement surgery. Short, medium and long term success rates of these hip prostheses are controversial in the literature. Traditional cemented and cementless hip prostheses have advantages and disadvantages affecting the success of the implantation process. In this study, a new design of hip prosthesis is presented considering the advantages and disadvantages of the prostheses. Femur and prostheses were modeled and combined with each other to perform the finite element analysis (FEA). The new design of prosthesis was compared to the conventional prosthesis in terms of mechanical aspects. The evaluation criteria are the maximum von Mises stress and micro-movement of the contact between femur and prosthesis. In conclusion, the new design of prosthesis was found to provide a sufficient amount of primary stability and decreased the risk of stress shielding.
