A modular humeral prosthesis, and modular instrumentation for preparing a humerus for same, and a method for implanting same

摘要

The present invention is a modular humeral prosthesis (11) for replacing at least a portion of the articulating surface of a proximal humerus (15) of a shoulder joint. The prosthesis (11) includes a stem module (27) for insertion into the proximal humerus (15), and an intermediate module (29) for adjustable attachment to the stem module (27). Modular instrumentation is provided for preparing the proximal humerus for the prosthesis. The instrumentation (111) includes a stem module (113) for extending into a medullary cavity in the proximal humerus (15), one or more rasp modules (115) for adjustable attachment to the stem module (113), and for preparing an enlarged mouth in the medullary cavity in the proximal humerus (15).
