Abstract: 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).

Abstract: The present invention relates to an apparatus and method to obtain bone fixation. More particularly, one embodiment of the present invention relates to a mechanism for achieving bone “through-growth” in a variety of orthopaedic applications. In one example (which example is intended to be illustrative and not restrictive), a prosthesis designed to achieve bone “through-growth” via one or more “windows” in a peg or keel structure may be provided (bone graft may be inserted into the peg or keel structure). In one specific example (which example is intended to be illustrative and not restrictive), a glenoid prosthesis (and associated method) may be used to resurface the scapula. In another specific example, the present invention may be used in the context of a partial or total shoulder arthroplasty.

Abstract: The invention concerns a surgical equipment provided with a total shoulder prosthesis comprising a hemispherical plate cap (20) and a prosthesis shank consisting of a humeral rod (1), a humeral plate (9) and a member (16) mutually locking the humeral rod and plate, with hemispherical contact surface (10a, 10b, 18) capable of allowing the humeral plate (9) of oscillating in all directions relative to the humeral rod (1), when the locking member (16) is in an unlocked position, and in locking the humeral rod and plate in the desired relative position.
