Patent ID: 8613774

Claim:
An elbow prosthesis comprising: a humeral component having a distal end and a proximal end, the proximal end having a humeral stem and the distal end including two distally extending condylar portions, each distally extending condylar portion having a hole extending therethrough and a condylar articulating surface; an ulnar component having a distal end and a proximal end, the distal end having an ulnar stem and the proximal end having an ulnar bearing component, the ulnar bearing component comprising complementary bearing surfaces that mate and articulate with the condylar articulating surfaces, the ulnar bearing component further including a central post extending between the two distally extending condylar portions that provides medial-lateral stability to the elbow prosthesis; an axle that is connected to the post of the ulnar component, wherein the two distally extending condylar portions rotate about the axle; and a humeral bushing assembly that includes a pair of humeral bushings that are received within the holes of the distally extending condylar portions of the humeral component; wherein the axle passes through the humeral bushings and through an opening formed in the post for detachably linking the humeral component to the ulnar component, wherein the axle includes a first end portion and an opposite second end portion, wherein each of the first and second end portions has a cross-sectional diameter that changes along a length of the respective end portion creating a barrel-shaped end portion with a central portion disposed therebetween, wherein the first and second barrel-shaped end portions are disposed on opposite sides of the post of the ulnar bearing component with the central portion of the axle being fixedly locked to the post.
