  • The Reliability of Modern Alumina Bearings in Total

    Ceramic bearing failure in total hip arthroplasty (THA) is a rare but serious complication. The incidence of such failures has declined steadily because of improvements in ceramic material quality, manufacturing methods, and implant design. The incidence of failures of the Biolox (CeramTec AG, Plochingen, Germany) forte brand of alumina components produced by CeramTec was 0.02%, or 2 in 10,000 ...
