Total arthroplasty of the hip by fritted alumina prosthesis. Experimental study and 1st clinical applications

A new material is proposed in total hip arthroplasty as a bearing component. The tolerance of dense ceramics was studied, as well as the anchorage of this material into bone. Physical, chemical and mechanical properties of the prosthesis were tested. Two hundred patients have already been operated on, but the follow-up is too short for any conclusion.
