CA 2155761

An implantable elbow prosthesis (1) comprises an ulnar component (2) and a humeral component (3) wherein the head (21) of the ulnar component is designed in a bifurcated shape with two horns (22, 23) and the head (31) of the humeral component comprises a rotatable spindle (34) between two projecting flanges (32, 33). The joint component of the prosthesis is formed by arranging the head (21) of the ulnar component to engage with the spindle (34) of the humeral component. In each of the horns (22, 23) on the ulnar component (2) there is provided a groove (24, 25) which terminates in a respective blind hole (24, 25) on each horn (22, 23). A C-ring form of clip (4) connects the heads (21, 31) of the ulnar component and the humeral component, while maintaining the desired degree of freedom of movement for the elbow joint and a predetermined tolerance of movement. The clip (4) embraces the spindle (34) on the humeral component (3) with a clearance (5) between the arc (43) of the clip and the spindle and is locked to the ulnar component (2), the ends (41, 42) of the clip being inserted into the grooves (24, 25) on the horns (22, 23) of the ulnar component and engaging with the blind holes (26, 27). This ensures that the ulnar component (2) does not lose its grip on the spindle (34) of the humeral component while at the same time the desired play is obtained in the actual joint connection, a vital circumstance for the functional characteristics of the prosthesis.
