Abstract
The hip is a ball and socket joint designed to bear the body mass as well as for facilitating the movement in many directions. Hip replacement is an operation to replace a natural hip joint with an artificial one. The aim of the present work is to conduct a parametric study that comprises the parameters affecting the strength of hip-joint cement fixation (offset distance and ball diameter), in order to come-up with the best combination for maximum strength. The results lead to recommending offset distance (3-6 mm) and ball sizes (34 and 50 mm) for maximum cement strength.
