Introduction: Osteolysis generated by wear debris remains a problem in total hip arthroplasty. Alternate bearings surfaces are sought in an attempt to reduce debris particles and prolong prosthetic wear. Ceramic on ceramic surfaces have a long clinical history but have encountered a number of problems due to design and material properties. Impingement with malposition of the components, ceramic chipping, and ceramic fractures with malposition of the acetabular component have been problems. |
