Patent ID: 8591592

Claim:
A method of shoulder repair, comprising the steps of: providing a humeral prosthetic comprising a spherical head having a convex surface suitable to be introduced within a joint cavity and a concave surface that is adapted to contact a humerus; providing a portal through the rotator cuff interval; forming a tunnel in the humerus at a defect location within the humerus; providing an articulating cutter comprising a cap and a reamer, the cap securely engaging the reamer through a ball joint with cross-pin fixation formed of a ball post and a pin that limits rotation but allows the cutter to articulate; inserting the articulating cutter through the rotator cuff interval portal; assembling the articulating cutter with a threaded pin and applying retrograde force while the articulating cutter cuts in a retrograde manner and through the preformed tunnel in the humerus to form a counterbore socket until the articulating cutter is flush with an articular surface of the humerus; removing the articulating cutter and the threaded pin; and installing the humeral prosthetic within the counterbore socket in the humerus.
