Failure of a titanium endoprosthesis--a case report.
A titanium-head Thomson endoprosthesis was revised 2.5 years after insertion. Metallosis with burnishing of the head and acetabular erosion were noted. The stem and the cement mantle were in perfect condition. Because this is not an isolated case, the author recommends that a titanium-stem endoprosthesis have a cobalt-chrome or ceramic bearing surface.
