Abstract: A glenoid component for coupling to a scapula of a subject includes a body. The body includes an articulation surface adapted to articulate with a humeral component, and the body further includes a distal surface adapted to face the glenoid of the scapula. The distal surface includes a base surface portion adapted to face a first portion of the glenoid. The distal surface further includes an augmented surface portion adapted to face a second portion of the glenoid. The base surface portion and the augmented surface portion define an obtuse angle therebetween.

Abstract: Reversed glenoid implants, and related kits and methods, are described that include an anchor member having a proximal head and a baseplate having a distal end with a first aperture sized to accept the proximal head of the anchor member. The proximal head is inserted along an un-threaded length thereof from the distal end into the first aperture, and the anchor member is restrained against axial translation with respect to the baseplate but is permitted to rotate with respect to the baseplate.

Abstract: An implant system for total shoulder arthroplasties, hemi shoulder arthroplasties, and “reverse” total shoulder arthroplasties including a humeral stem having an enlarged head portion with interfaces adapted to removably receive various modular interchangeable components, such as articulating liners, spacers, and adapter inserts. The humeral stem functions as a universal platform that may be used in either conventional or “reverse” total shoulder arthroplasties, as well as hemi shoulder arthroplasties, and may remain implanted in place during a revision in which the implant system is converted between the foregoing configurations, for example.

Abstract: This surgical instrumentation assembly is for positioning a shoulder prosthesis, the shoulder prosthesis comprising a patient-specific shoulder implant adapted to fit onto a glenoid cavity of the scapula of a patient. The assembly comprises a patient-specific impacting device having an underside surface congruent with the glenoid cavity of the scapula of the patient, said underside surface being provided with protrusions adapted to perforate the cortical bone of the scapula upon impact of the impacting device against the scapula by a one-sided translation movement.

Abstract: Modular humeral implants and methods of use. A humeral implant can include a stem portion, a metaphyseal portion, a locking element, and an intermediate portion. 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: 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.

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.
