Abstract

THIS STUDY REPRESENTS THE USE OF A HOLLOW STEMMED HIP PROSTHESIS TO REDUCE THE STRESS CONCENTRATIONS AND MAINTAIN UNIFORMITY OF STRESS DISTRIBUTION OVER THE IMPLANT-CEMENT INTERFACE REGION. A THREE-DIMENSIONAL FINITE ELEMENT MODEL OF A PROXIMAL FEMUR AND FEMORAL COMPONENT OF HIP IMPLANT WAS CONSTRUCTED. THE IMPLANT STEM WAS ASSUMED AS A HOLLOW CYLINDER IN WHICH DESIGN VARIABLES ARE LENGTH OF THE STEM, LENGTH OF THE CYLINDRICAL HOLE AND ITS RADIUS. RESPONSE SURFACE METHOD AND SENSITIVITY STUDY WERE COMBINED WITH FINITE ELEMENT TECHNIQUE TO GENERATE UNIFORM STRESS DISTRIBUTION OVER THE INTERFACE REGION BY CHANGING THE DESIGN VARIABLES. OPTIMUM RESULTS INDICATED THAT THE LENGTH OF THE STEM HAS MAJOR IMPACT ON THE OPTIMIZATION OUTCOME WHILE THE LENGTH AND THE RADIUS OF THE INTERNAL CYLINDER HAS THE SECOND ROLE.
