摘要：
A prosthetic humeral head component 60 comprising a convex external head surface 62, an internal cavity formed opposite to the head surface 62 and a plurality of fixation elements 70 protruding from said cavity oppositely to said head surface 62 for location into a peripheral portion of an epiphyseal plate of the humerus to secure the head cap 60 to the humerus. The component is formed as a single, unitary piece, preferably ceramic with an osteoconductive coating. The fixation elements may comprise pegs 70, fins, keels or combinations thereof. The internal cavity may be frusto-conical, having a circumferential wall and a ceiling. The fixation elements may extend from the wall or the ceiling, and may extend further than the edge of the external surface 62.
