HUMERAL COMPONENT OF A SHOULDER JOINT PROSTHESIS

摘要

A humeral component of a reverse shoulder prosthesis comprises an elongate stem part for location within the intramedullary cavity of the humerus, and an epiphyseal part having a concave bearing surface for articulation with the convex bearing surface of a glenoid component. The elongate stem part defines a stem axis and the concave bearing surface of the epiphyseal part defines an epiphyseal axis. The epiphyseal axis is offset posteriorly relative to the stem axis.
