PROSTHETIC JOINT

摘要

A prosthetic joint has a central axis and includes: (a) a first member of rigid material and including a body having a cantilevered perimeter flange extending therefrom, the flange defining a wear-resistant, concave first contact surface having a protruding rim and a recessed central portion; and (b) a second member of rigid material with a wear-resistant, convex second contact surface. The first and second contact surfaces bear directly against each other so as to transfer axial and lateral loads from one of the members to the other, while allowing pivoting motion between the two members. The flange is shaped and sized so as to deform elastically and permit the first contact surface to conform in an irregular shape to the second contact surface when the joint is placed under a predetermined load.
