Abstract:
1. A prosthetic joint, comprising: (a) a first member comprising a first rigid material and including a wear-resistant, concave interior defining a cup surface; and (b) a second member comprising a second rigid material which is the same as or different from the first rigid material, the second member including a wear-resistant, convex contact surface, (c) wherein the surface of a selected one of the members includes: (d) where the first and second contact rims bear directly against the surface of the other of the members, so as to transfer axial and lateral loads between the first and second members, while allowing pivoting motion therebetween; and (e) wherein the flanges are shaped and sized so as to deform elastically and permit the first and second contact rims to conform in an irregular shape to the surface of the other of the members, when the joint is placed under a predetermined load.
