Ceramic On Ceramic Hip Replacement Bearings

The clinical use of ceramic as a bearing surface dates back to the early 1970s.
Ceramic on ceramic hip replacement bearings. The aim of this systematic review is to answer three questions. The type of ceramic used in total hip replacement today is aluminum oxide also known as alumina. The alternative bearing couples such as metal on polyethylene and metal on metal are more inclined to wear and produce particulate debris. Ceramic bearing surfaces are increasingly used for total hip replacement notwithstanding that concern is still related to ceramic brittleness and its possible mechanical failure.
Interest in ceramic on ceramic hip replacement is increasing as a result of the realization of osteolysis associated with wear debris generation in conventional metal on polyethylene bearings and metallosis associated with metal on metal articulations.

There is minimal dimensional mismatch between the head and cup and there is no translational movement. Modern manufacturing techniques and developments have increased the strength and reliability of ceramic materials.
Ceramic on ceramic hip prostheses are an increasingly popular choice for hip replacement. In 1995 an improved alumina ceramic was developed that had increased purity and strength over the first generation materials.
