Multi-component shoulder implant assembly with dual articulating surfaces

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 therefrom such that the base is adapted to mount to a reconditioned glenoid cavity defined in the scapula, said element exhibiting a second convex exterior surface projecting from the bone surface;
• a receiver component having a base with a first convex bone contacting surface adapted to being mounted to a reconditioned humeral head associated with the humerus, said receiver component exhibiting a second convex exterior surface projecting away from the bone surface and exposing a concave profile exhibiting only a rim edge therebetween at an outer exposed seating end of said second convex surface, said second convex exterior surface of said pseudo-spherical shaped element articulating relative to said concave profile, 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 of said receiver component.
