Abstract
Two different types of surgery methods, cemented and uncemented, are generally used in surgery applications having advantages and disadvantages for each other in long term use. In particular, the use of traditional hip prostheses has some disadvantages due to mechanical problems that trying to be eliminated by developing many different designs. One of the main problems of the use of hip prostheses is not transferred the bodyweight regularly through the prostheses. In this study, a new hip prosthesis design is developed to transfer the body weight to lower extremity without damaging. Both femur and prostheses were modeled using a 3D solid modeling technique and were mounted to each other. The prepared femur-prostheses pairs were transferred into ANSYS Workbench software to simulate using the Finite Element based technique and subjected to the body weight and muscle forces to calculate stresses and strains. The von Mises stresses on the prostheses were examined to evaluate the prosthesis strength. The maximum axial strain values were obtained and evaluated to determine the stress shielding. Based on the results, the new design prosthesis has the risk of lower stress shielding and lower risk of failure. Therefore, the new hip prosthesis design may be used to eliminate the disadvantages in the traditional hip prostheses.
