Ten- to 14-year results of a ceramic hip prosthesis : Alumina ceramic arthroplasty

One hundred total hip arthroplasties with a cementless aluminum oxide socket and ball with different types of cemented metal femoral stems were performed from 1974 to 1979. All were primary implantations. These cases were recently reviewed in a ten- to 14-year follow-up evaluation. Despite extensive laboratory testing of the ceramic material, a significant number of cases resulted in a very unfavorable result such as extensive wear, ball fracture, or migration of the socket
