Abstract

Hip arthroplasties are commonly performed in Orthopaedic Surgery. Many different prostheses design are available. According to the type of the prostheses, different stresses are recorded. In this study the straight system and anatomic type protheses with angled stem are used and strains induced here record different strains according to the geometrical designs and properties. Three different femurs have been obtained from middle-aged, male cadavers, and these femur models have been modelled by using solid material. Straight system and the angled stem prostheses were also modelled by solid material. As a result, the straight system prostheses have been found more advantageous when compared with the angled stem prostheses in the strain forces to the bone and in the loosening of the prostheses.
