ARTIFICIAL CUSHION JOINTS AND METHODS OF MAKING THE SAME

摘要

A prosthetic bearing component for use in joint replacement comprising a first element having a first magnetized layer (26) disposed thereon, configured with a pole (N) facing in a proximal direction, and a second element having a second magnetized layer (36) disposed thereon. The second element is configured to engage the first element, and the second magnetized layer (36) is configured with an equivalent pole (N) facing in a distal direction, whereby the pole (N) of the first magnetized layer (26) is positioned opposite the equivalent pole (N) of the second magnetized layer (36) such that a repellant force is created therebetween. The prosthetic bearing component further having a corrosion resistant layer (24, 34) covering the first and second magnetized layers (26, 36), and a wear resistant layer (22, 32) covering the corrosion resistant layer (24, 34) and forming a bearing surface of the prosthetic bearing component.
