Glenoid component installation tools

摘要

The present invention relates to instruments for preparing a glenoid surface of a scapula to receive a prosthetic glenoid component to replace the natural socket of a shoulder. More particularly, the present invention relates to a drill guide assembly for aligning and guiding a drill bit to form holes in the glenoid surface at predetermined locations to secure the glenoid component to the glenoid surface. A reamer assembly including a ratchet drive mechanism is also included to facilitate preparation of the glenoid surface prior to installation of the glenoid component.
