Embodiment Construction

[0019]FIG. 1A shows a schematic view of a prosthesis 10 including a glenoid component 12, a humeral component 14 and an interpositional implant 16. The glenoid component 12 is implanted in the scapula S of the gleonid G. The method and apparatus of the various embodiments of the present invention disclosed herein may be used with a variety of glenoid components, such as for example those disclosed in U.S. Pat. Nos. 7,033,396; 6,953,478; 6,761,740; 6,626,946; 5,702,447 and U.S. Publication Nos. 2004 / 0220673; 2005 / 0278030; 2005 / 0278031; 2005 / 0278032; 2006 / 0020344, which are hereby incorporated by reference. Although the prosthesis 10 is primarily discussed as being implanted in a patient's shoulder, the prosthesis 10 may also be modified and implanted in other locations of a patient's body without departing from the intended scope of the present invention. For example, the prosthesis 10 may be modified to be implanted in a patient's hip, ankle, hands, or feet.

Abstract

A method for implanting an intra-articular shoulder prosthesis is provided. The method includes removing a proximal portion of a humerus. The proximal portion of the humerus preferably forms a resected portion. The resected portion has a convex outer surface and an inner surface. The method further includes engaging the convex outer surface of the resected portion with a cut surface of the proximal portion of the humerus. The cut surface of the proximal portion of the humerus and / or the inner surface of the resected portion are optionally processed to form a generally concave surface, such as by impacting. In one embodiment, the inner surface of the resected portion is impacted into engagement with the cut surface of the proximal portion of the humerus. The generally concave inner surface of the resected portion forms a concave articular surface to receive an interpositional implant.
