Mechanical devices such as prosthetic knees, hips, shoulders, fingers, elbows, wrists, ankles, fingers and spinal elements when implanted in the body and used as articulating elements are subjected to wear and corrosion. These prosthetic implants are usually fabricated in modular form from combinations of metallic materials such as stainless steels, Co-Cr-Mo alloys, and Ti-Al-V alloys; plastics such as ultrahigh molecular weight polyethylene(UHMWPE); and ceramics such as alumina and zirconia. As the articulating surfaces of these materials wear and corrode, products including plastic wear debris, metallic wear particles, and metallic ions will be released into the body, transported to and absorbed by bone, blood, the lymphatic tissue, and oner organ systems. This invention provides prosthetic implants having articulating surfaces that exhibit a reduced rate of release of wear debris and metal ions into the body and a method of producing such prosthetic implants.
Des dispositifs mécaniques tels que des genoux, hanches, épaules, doigts, coudes, poignets, chevilles, doigts et éléments spinaux prosthétiques, lorsquils sont implantés dans le corps et utilisés en tant quéléments darticulation, sont soumis à lusure et à la corrosion. Ces implants prosthétiques sont généralement fabriqués sous forme modulaire à partir de combinaisons de matériaux métalliques tels que des aciers inoxydables, des alliages Co-Cr-Mo, et des alliages Ti-Al-V ; de matières plastiques tels que le polyéthylène de poids moléculaire très élevé (UHMWPE) ; et de céramiques telles que lalumine et la zircone. Au fur et à mesure que ces matériaux susent et se corrodent, des produits comprenant des débris dusure de matière plastique, des particules dusure métalliques et des ions métalliques sont libérés dans le corps, transportés vers et absorbés par les os, le sang, le tissu lymphatique et dautres systèmes dorgane. La présente invention concerne des implants prosthétiques ayant des surfaces darticulation qui présentent un taux réduit de libération de débris dusure et dions métalliques dans le corps et un procédé de production de tels implants prosthétiques.
