Abstract:
1. An implant assembly for re-establishing a glenohumeral joint between a scapula and humerus, comprising: a pseudo-spherical element having a base with a first convex bone contacting surface, said base terminating in a stem portion extending perpendicularly therefrom such that the base is adapted to mount to a reconditioned glenoid cavity defined in the scapula; said element exhibiting a second convex circumferentially extending exterior profile projecting away from the bone surface and a recessed concave profile exhibiting only a rim edge therebetween at an outer exposed seating end of said second convex surface, a first axis extending through a central location of said concave profile defining a non-collinear angle relative to a second axis extending through a centerline of said stem portion; a receiver adapted to being mounted to a reconditioned humeral head associated with the humerus, said receiver exposing a second concave profile; and a spherical element interposed between said pseudo-spherical element and said receiver a first convex portion of said spherical element articulating relative said recessed concave profile of said pseudo-spherical element, a second convex portion of said spherical element articulating relative said second concave profile of said receiver.
