Hip replacement metal on crosslinked polyethylene (MOXP), ceramic on ceramic (COC), ceramic on crosslinked polyethylene (COXP) and metal on metal (MOM). Each combination has different advantages and disadvantages. Post-operative projectional radiography is routinely performed to ensure proper configuration of hip prostheses. The direction of the acetabular cup influences the range of motion of the leg, and also affects the risk of dislocation. For this purpose, the "acetabular inclination" and the "acetabular anteversion" are measurements of cup angulation in the coronal plane and the sagittal plane, respectively. Risks and complications in hip replacement are similar to those associated with all joint replacements. They
