Patent ID: 11129725

Abstract:
Disclosed is a distal radio ulnar joint prosthesis system, and the method of use for the same, the system comprising an ulnar stem component, and ulnar head component, a set screw, and a sigmoid notch component, the system providing a prosthesis for replacement of the distal radio ulnar joint to restore the pronation-supination motion of the forearm as well as stability between the ulna and radius; a DRUJ prosthesis adapted for rotational alignment of the replacement joint along the axis of forearm rotation; a DRUJ prosthesis which allows for the use of a number of different sized heads having differing geometries; a DRUJ prosthesis adapted for variable pivoting alignment between the replacement distal ulnar head and the ulna; and a DRUJ prosthesis adapted for adjustment in the alignment between the articulating surface of the ulnar head and the sigmoid notch.
