Localized femoral osteolysis in cementless ceramic total hip arthroplasty.

Abstract

A retrospective review revealed localized femoral osteolysis occurred in 8 out of 134 cementless ceramic total hip arthroplasties (6.0%) performed during an average 9-year period. The average latent period was 8 years. The lesion was usually located in the deeper periprosthetic area. Localized osteolysis usually occurred after loosening of the femoral stem, suggesting the pathogenesis may be a foreign-body reaction to the ceramic debris.
