Ceramic On Ceramic Hip Replacement Bearings

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.

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. Ceramic on ceramic hip prostheses are an increasingly popular choice for hip replacement. Modern manufacturing techniques and developments have increased the strength and reliability of ceramic materials.

1 are there risk factors for ceramic component fracture following total hip replacement. At present ceramics are used only in the hip because hip components have simple design and shape. In 1995 an improved alumina ceramic was developed that had increased purity and strength over the first generation materials. Ceramic bearing surfaces are increasingly used for total hip replacement notwithstanding that concern is still related to ceramic brittleness and its possible mechanical failure.

There is minimal dimensional mismatch between the head and cup and there is no translational movement. Miki et al mid term results of cementless total hip replacement using a ceramic on ceramic bearing with and without computer navigation j bone joint surg br 89b 2007 p.
