Abstract
A humeral prosthesis includes a stem component and a partial humeral head component. The partial humeral head component has a configuration that is similar to the curvature of the humeral head to allow the head to reconstruct the anatomy of the damaged humerus. The stem component is threaded and cannulated and engages the partial humeral head component. The stem component is configured to be inserted within the humeral diaphyseal channel.

A prosthetic for replacing a portion of a bone, comprising:
- a post having a proximal end and a distal end;
- a spherical head secured to the proximal end of the post, the spherical head having a convex surface suitable to be introduced within a joint cavity and a concave surface that contacts the bone;
- and
- a coupling element for attaching the post to the spherical head.
