Orthopedic implants which include the components of zirconium or zirconium- based alloys having surfaces coated with oxidized zirconium or alternatively, other orthopedic implants comprising abrasion resistant surfaces contacting surfaces of cross~linked polyethylene are disclosed. Such implants provide low friction, highly wear resistant coatings especially useful in artificial joints, such as hip joints, knee joints, elbows, etc., but also useful in other implant devices as well. The implants also find use as vertebral disc prostheses.
L'invention concerne des implants orthopédiques contenant des composants de zirconium ou d'alliages à base de zirconium présentant des surfaces revêtues au moyen de zirconium oxydé. En variante, l'invention concerne d'autres implants orthopédiques comportant des surfaces de contact résistantes à l'abrasion, en polyéthylène réticulé. Ces implants comportent des revêtements hautement résistants à l'usure, à faible frottement. Lesdits revêtements sont particulièrement utiles pour les articulations artificielles, telles que l'articulation de la hanche, du genou, du coude, etc., ainsi que pour d'autres dispositifs implants. Les implants selon l'invention peuvent également être utilisés comme prothèses de disques vertébraux.
