Modular prosthesis

摘要

A modular shoulder prosthesis for the replacement of a portion of the humerus is provided. The prosthesis is assembled from a kit that includes a stem sized to be received in the humerus, a body sized to replace a portion of the humerus, the body being attachable to the stem, and a head member sized to replace the head of the humerus, the head member being eccentrically attachable to the body. A collar is inserted between the head member and the body to help stabilize the assembled prosthesis.
