Abstract: A glenoid component in one embodiment includes a base component with a planar upper circular rim defining a first plane, a receptacle opening to the first plane, and a lower planar circular surface defining a second plane parallel to the first plane. An articulating component of the glenoid component includes an upper articulating surface, a lower cylindrical coupling portion configured to be inserted into the receptacle, and an overhang portion located above the lower cylindrical coupling portion and beneath the upper articulating surface. The overhang portion includes a planar lower surface extending outwardly from the lower cylindrical coupling portion and configured to abut the planar upper circular rim of the base component when the articulating component is coupled to the base component.

Abstract: A prosthesis assembly for use with a scapula is disclosed. The prosthesis assembly includes a glenoid bearing support and a bearing. The glenoid bearing support includes a glenoid vault-occupying portion configured to occupy at least a portion of a glenoid vault of the scapula, the glenoid-vault occupying portion having a first coupling component. The glenoid bearing support further includes a glenoid rim replacement portion attached to the glenoid vault-occupying portion. The bearing defines a bearing surface and has a second coupling component configured to cooperate with the first coupling component to couple the bearing to the glenoid vault-occupying portion. The glenoid vault-occupying portion defines a bearing-side end portion and an opposite-side end portion. The glenoid rim replacement portion projects outwardly from the bearing-side end portion of the glenoid vault-occupying portion. The glenoid bearing support defines a bone graft receptacle.
