The recess can be configured to secure a coupling of a shoulder articular body directly to the interior surface.

Abstract: Embodiments of the present invention include a convertible prosthesis that is capable of conversion from a humeral head replacement to a reverse reconstruction without any removal of parts integrated into the patient's bony anatomy (e.g. implant stems). A desired overall implant inclination angle may be achieved by matching various implant stems with various reverse inserts, thus permitting a resection surface to be matched with an implant stem selection while also permitting a desired overall implant inclination angle to be achieved through the selection of an appropriate insert.

Abstract: Provided is a method of resecting a humerus, including positioning a multi-part guide on the humerus, where the multi-part guide includes a support portion and a positioning jig; advancing at least two mounting pins through the support portion along diverging paths; removing the positioning jig; and resecting the humerus with reference to a cutting surface of the support portion.

Abstract: A shoulder assembly is provided which includes a base member including a collar; a helical structure extending from the collar in a distal direction; and a first pathway projecting distally of the collar and through the helical structure adjacent to an inner periphery thereof, the first pathway being generally transverse to the helical structure and extending in a space between successive portions of the helical structure; and a locking device comprising a proximal support and a first arm projecting distally of the proximal support, the first arm configured to be disposed in the first pathway projecting distally of the collar when the proximal support is disposed adjacent to the collar; where the first arm is disposed through bone in the space between successive portions of the helical structure when the shoulder assembly is implanted.

Abstract: A method of guiding a glenoid prosthesis is disclosed. The method includes preoperatively determining a position and an orientation of a guide feature of a glenoid guide of the present disclosure based on a scapula of a specific patient, and engaging the glenoid guide with the scapula; and inserting a pin having an axis through the guide feature to or through the scapula.
