Abstract:
1. A reverse shoulder assembly comprising: a glenoid component comprising a glenosphere and a glenoid attachment means; and a humeral component, wherein the motion inducing element and the motion inducing guiding surface are sufficiently designed so that, when the glenoid component is implanted in a glenoid, and when the humeral component is implanted in a humerus, an interaction between the motion inducing element and the motion inducing guiding surface alters the abduction motion of the humerus relative to a scapula into a forward flexion motion of the humerus relative to the scapula, wherein the interaction between the motion inducing element and the motion inducing guiding surface further alters the abduction motion of the humerus relative to the scapula into an external rotation motion of the humerus relative to the scapula, wherein the motion inducing element has a geometry capable of altering the direction of the induced motion at varying humeral positions.
