The prosthesis is assembled from a kit (10) that includes a stem (20a, 30b) sized to be received in the humerus, a body (30a, 30b) sized to replace a portion of the humerus, the body (30a, 30b) being attachable to the stem (20a, 20b), and a head member (44a, 44b, 44c) sized to replace the head of the humerus, the head member (44a, 44b, 44c) being eccentrically attachable to the body (30a, 30b). A collar (59a, 59b, 59c) is inserted between the head member (44a, 44b, 44c) and the body (30a, 30b) to help stabilize the assembled prosthesis.</p> |
