Abstract

A shoulder arthroplasty apparatus includes a stemless humeral head (2) for coupling to a previously cut humeral surface (26). The base (8) of the humeral head (2) has a stabilizing base extension that is impacted into a cancellous region (34) of the cut humeral surface (26). A preferred base extension has a cruciform shape including two planar fins (10) intersecting at or near the center of the base (8). The periphery (22) of the humeral head (2) is formed to match the cortical margins (32) of the cut humeral surface (26). The humeral head (2) is preferably cemented or press-fit to the humeral surface (26). The humeral head (2) has any of a range of peripheral shapes and sizes matching the specific shape and size of the anatomic neck (31) of a humeral surface (26).
