Various embodiments of the present invention relate to an apparatus and method for reverse shoulder arthroplasty (e.g., reverse total shoulder arthroplasty). In one specific example, a glenoid component used to resurface the scapula may be provided. Of note, unlike traditional total shoulder arthroplasty the glenoid component in a reverse shoulder is convex rather than concave; it acts as a physical stop to prevent the superior migration of the humeral head—a typical occurrence in patients suffering from rotator cuff tear arthropathy (CTA).

A glenoid implant assembly is provided. The assembly includes a first component for attachment to the glenoid fossa of a scapula. The component defines an assembly face of the component. The assembly also includes a second component removably secured to the first component. The second component includes an assembly face of the second component. The assembly face of the second component is in close approximation to the assembly face of the first component. The second component is attachable to the first component in a direction generally normal to the assembly faces.

A method comprises: forming a planar bone surface at a glenoid using a guide pin; forming a first bore into the glenoid located near theguide pin; forming a second bore into the glenoid offset from the first bore; inserting an augment ream guide into the first and second bores; and forming an angled bone surface at the glenoid relative to the planar bone surface using the augment ream guide. A ream guide comprises: a base having first and second surfaces; a bone peg extending from the first surface; an alignment peg spaced from the bone peg; and a guide peg extending from the second surface at an oblique angle to the bone peg.

A stabilizing scapular rehabilitation brace that operates to aid patients in rehabilitating their shoulder joint in an anatomically correct manner with the trapezius is locked down in order to prevent substantial upward shoulder shrug movements. The stabilizing scapular rehabilitation brace includes a shoulder harness, a stabilization strap, and a thigh strap, with the stabilization strap operating to both tighten the shoulder harness on a user and connect and anchor the shoulder harness to the thigh strap. With the shoulder harness operating to keep the user's shoulder blades retracted and the thigh strap and stabilization strap preventing the shoulder harness, these components work together to emulate the same “hand on trapezius area” function that therapists manually apply to patient rehabbing a shoulder condition in-clinic.
