Abstract:

Background  

Ceramic bearings in total hip arthroplasty (THA) have been introduced in clinical practice to minimize the problem of polyethylene particle–induced osteolysis. The aim of the study is to report the results of 68 consecutive alumina-on-alumina THAs done in 61 patients for avascular necrosis (AVN) of the femoral head.
Keywords:Avascular necrosis  Hip arthroplasty  Alumina-on-alumina ceramic bearings
