Abstract

A composite and metal prosthetic component has a metal pyramid insert. The insert part includes a pyramid part and a stem having at least one slot in its bottom. Composite material may fill the spot to prevent rotation of the stem within the composite base. An annular, part spherical aluminum dome is molded onto the composite part at a position to act as a contact surface for parts mating with the pyramid part.
