<p>The present invention is directed to a modular shoulder prosthesis (22) having an adjustable radial offset and/or angular inclination provided by relative rotation of an adapter (24) interdisposed between the stem (28) and the head (26). Specifically, the interface (48 & 38) configuration between the stem (28) and the adapter (24), as well as between the adapter (24) and the head (26) are designed such that relative positioning of these components provides a continuous adjustment in the radial offset and/or angular inclination. Indicia (62) are provided at the interface between the adapter (24) and the head (26) to precisely determine the magnitude and direction of the adjustment being made.</p> |
