Abstract:
1. A prosthetic joint, comprising: (a) first member having a balanced centroidal axis, the first member comprising a rigid material and including a concave interior defining a cup surface, the cup surface including: (b) a second member comprising a rigid material with a wear-resistant, convex contact surface; (c) where the first and second contact rims bear directly against the contact surface of the second member, so as to transfer axial and lateral loads between the first and second members, while allowing pivoting motion between the first and second members; and (d) wherein the flange and the contact ring 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 contact surface, when the joint is placed under a predetermined load.
