A head for a modular humeral (or hip) prosthesis which mates couplingly to a head mounting seat on the end of on elongated humeral stem is described. The head has an enganing syherical shaped outer surface which has a radius measured from a center which lies along an offset line which is inclined at an angle which ranges from between 10 to 30 degrees from the normal longitudinal axis of the elongated stem. The head has a longitudinal axis which is shifted form between 2. 5 to 7. 5 mm from a normal longitudinal axis. The elongated humeral stem includes a shaft seat which passes through the head mounting seat, which is adapted to receive a shaft extending from head. An adjustable to receive a shaft extending from the head. An adjustable interlocking alignment pin ensures desired orientation between the head and the head mounting seat during mating of the parts and maintains stability of orientation when mated.

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.

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).
