A glenoid component affixed to a glenoid bone having an end surface and an outer side surface, the glenoid component being engageable by a humeral part. The glenoid component includes a tray portion for overlying the end surface (articulating surface) of the glenoid bone. The tray portion has an outer major side surface for engagement with the humeral part and an outer periphery. A first tab extends axially from the outer periphery of the tray portion for engagement with the posterior outer side surface of the glenoid bone. A second tab extends axially from the outer periphery of the tray portion for engagement with the anterior outer side surface of the glenoid bone. The tabs fix the glenoid component in place on the glenoid bone.
