Claim Text:
1. A method of installing a prosthesis assembly, comprising: installing a base component in a prepared glenoid vault; selecting a glenoid bearing component including a bearing surface comprising a first articulating portion partially surrounded by a first rim portion, a second articulating portion partially surrounded by a second rim portion, and a third articulating portion partially surrounded by a pair of spaced apart third rim portions, wherein the first rim portion, the second rim portion, and the pair of spaced apart third rim portions define a non-circular shape when projected onto a plane, and the first rim portion has a first radii of curvature on the plane, the second rim portion has a second radii of curvature on the plane; axially aligning a plurality of slots in one of the glenoid bearing component and the base component with a plurality of ridges in the other of the glenoid bearing component and the base component, each of the plurality of slots having a maximum length which is greater than a maximum length of a respective one of the plurality of ridges; engaging each of the plurality of ridges with the respective one of the plurality of grooves thereby rotatably coupling the glenoid bearing component and the base component and limiting axial movement of the glenoid bearing component relative to the base component; and placing the bearing surface into articulating contact with a humeral head.
