Patent ID: 8840672

Claim:
A method of implanting a shoulder prosthetic, the method comprising: implanting a glenoid tray into a resected glenoid, the glenoid tray having a glenoid interface surface, an opposed bearing mounting surface, and a stem extending from the glenoid interface surface along a longitudinal axis in a direction away from the opposed bearing mounting surface; providing an articulating bearing; engaging the bearing mounting surface with an interface surface of a bearing coupling member; mating a bearing coupling surface of the bearing coupling member to a corresponding surface on the articulating bearing such that the bearing coupling member extends along the longitudinal axis; and coupling a spring to the articulating bearing and one of the glenoid tray and the bearing coupling member such that the bearing coupling member remains movable along the longitudinal axis with respect to at least one of the articulating bearing and the glenoid tray after implantation of the prosthetic.
