Abstract

A humeral component of a reverse shoulder prosthesis (2) comprises an elongate stem part (4) for location within the intramedullary cavity of the humerus, and an epiphyseal part having a concave bearing surface (12) for articulation with the convex bearing surface (12) of a glenoid component (8). The elongate stem part (4) 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.

Description

technical field

[0001] The present invention relates to a humeral component in a reverse shoulder prosthesis. Background technique

[0002] A shoulder prosthesis includes a humeral component having a shaft section that can fit within the intramedullary cavity of the humerus, and a glenoid section. In a natural joint, the humeral component provides a convex head that is articulated on a concave bearing surface on the glenoid socket. This structure is reproduced in so-called "anatomical" shoulder prostheses, in which the humeral component includes a stem section and a head section with a convex load-bearing surface, and the glenoid component provides a concave into the bearing surface. The shaft segment is implanted within the humerus. The head section is fitted onto the shaft section (typically using a spigot and socket arrangement) such that the head section rests above the resection plane of the humerus. Anatomical prostheses are suitable for use in patients in which th...
