Abstract:
1. A prosthetic comprising: a glenosphere defining an articulating surface; a glenoid tray defining an interior coupling bore having a planar locking surface; a bushing member disposed within the glenoid tray, the bushing member defining an aperture having a plurality of generally planar bearing surfaces and forming a bushing member bearing ledge; and a bearing coupling member disposed within the bushing member, the bearing coupling member having a planar interface surface configured to engage the bushing member bearing ledge, the planar interface surface having a coupling flange extending generally perpendicular therefrom, the coupling flange having a depending locking member configured to be disposed through the interior coupling bore and to engage the planar locking surface, the bearing coupling member having a bearing coupling side having a coupling member surface configured to mate to a corresponding glenoid coupling surface on the glenosphere.
