Abstract

An implant assembly for re-establishing a glenohumeral joint between scapula and humerus bones. A ball has a first exposed convex support surface and a first reverse convex bone contacting surface extending from a first annular perimeter edge established with the first convex support surface. A first stem extends from the first reverse convex surface such that the first reverse convex surface and first stem are adapted to being mounted into a reconditioned glenoid cavity defined in the scapula. A receiver has a second exposed convex surface, a rim edge extending about a portion of said second exposed convex surface and defining a concave profile recessed within the second exposed convex surface and so that the concave profile seats a portion of the first exposed convex surface of the ball in an articulating relationship. The receiver further has a second reverse convex bone contacting surface extending from a second annular perimeter established with the second exposed convex surface. A second stem extends from the second reverse convex surface such that the second reverse convex surface and the second stem are adapted to being mounted to a reconditioned humeral head associated with the humerus.
