Abstract:
1. An ulnar assembly for use with a humeral component to form an elbow prosthesis, said ulnar component comprising: a stem component including a portion thereof defining a stem for implantation in a cavity formed in the ulna, said first component defining a longitudinal axis thereof generally coincident with the longitudinal axis of the ulna; a semi-constrained component attachable to said stem component, said semi-constrained component attachable and removable from said stem component along the longitudinal axis of the stem component, wherein one of said stem component and said semi-constrained component comprises an external taper and wherein the other of said stem component and said semi-constrained component defines an internal taper therein adapted to receive said external taper; and an unconstrained component attachable to said stem component, said unconstrained component attachable and removable from said stem component along the longitudinal axis of the stem component, wherein one of said stem component and said unconstrained component comprises an external taper and wherein the other of said stem component and said unconstrained component defines an internal taper therein adapted to receive said external taper.
