title: [Experimental determination of the wear of biomaterials used in the construction of hip arthroprosthesis].
abstract: The author reports the results of an experimental test using a "hip simulator" to evaluate the wear rate of hip prostheses. The following couplings were tested: Cobalt-Chromium-Molybdenum (CoCrMo)-Ultra High Molecular Weight Polyethylene (UHMWPE), Alumina (Al203)-Ultra High Molecular Weight Polyethylene (UHMWPE) and Alumina (Al203)-Alumina (Al203). The Results obtained emphasize that the tribologic properties of alumina are better than those of the other materials tested.
