ABSTRACT:
A glenoid component for a shoulder prosthesis includes a body having a concave lateral articulating surface and an opposing medial surface with a stem extending along a central axis from said medial surface. The medial surface includes a central portion extending outwardly from the central axis and tapering toward said lateral articulating surface from an area of greater thickness of said body in the vicinity of said central axis to an area of lesser thickness outwardly from said central axis. Under one embodiment the body portion has an edge having a generally circular configuration while under a second embodiment the body portion includes an edge having a non-circular configuration and the tapering central portion terminates in a circular line of termination which is spaced from said edge in one or more areas and cooperates with said edge to define one or more extension portions. A method for and apparatus for use in implanting the glenoid component includes a combination sizer and guide and a reamer having a tapered cutting edge extending from a head in which a peripheral edge portion is contoured to engage the glenoid surface to prevent reaming to an excessive depth.
