The intermediate portion can include at least one spacer. Each spacer can include a proximal engagement feature, a distal engagement feature, a lumen extending longitudinally through the spacer, and a pin slidable within the lumen of the spacer. Distal movement of a locking element in the metaphyseal portion can translate the pin of each spacer to secure the metaphyseal portion, the intermediate portion, and the stem portion in a locked configuration.

Abstract: An orthopedic driver is provided that includes an elongate tubular body and an indicator assembly. The indicator assembly has a housing that has at least one opening and a visual indicator disposed in the at least one opening. The visual indicator is configured to be coupled with a guide pin such that lateral movement of the elongate tubular body relative to the guide pin causes the visual indicator to move between a flush or recessed configuration within the housing and an extended configuration. In the extended configuration, the visual indicator extends outward of an outer surface of the housing. The flush or recessed configuration corresponds to alignment of the guide pin relative to the elongate tubular body and the extended configuration corresponds to misalignment of the guide pin relative to the elongate tubular body.

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: A method and apparatus of reattaching a bone fragment to a proximal humerus of a humerus in a shoulder joint. The method includes introducing a distal end of the humeral nail into a medullary canal of the humerus. A first proximal screw is engaged with the bone fragment and a first proximal bore in the proximal end of the humeral nail to move the bone fragment toward the proximal humerus. The humeral nail and the attached bone fragment are rotated relative to the medullary canal of the humerus to position the bone fragment to an anatomically optimal location. The bone fragment is preferably one of a greater or lesser tuberosity of the proximal humerus. The method and apparatus can be used to reattach bone fragments in a variety of other joints.
