Hip Replacement

Hip prostheses are generally made up of two main parts: the acetabulum and the thigh. In the old systems, the pelvic part was made of very high molecular weight polyethylene (UHMWPE) and the thigh part was made of steel with a coating of titanium, chromium and cobalt or other intermediate metals. These two pieces were attached to the patient’s bone by bone cement (polymethyl methacrylate).

They do not use bone cement to attach newer prostheses, but embed the prosthesis with the help of friction force and compression method. In these prostheses, the pelvic cavity consists of a metal bowl that is attached to the pelvis and a polyethylene cover is placed between it and the thigh.

New prostheses are very diverse in terms of type of parts, material, and design, and they are used according to the taste and diagnosis of surgeons.
