ABSTRACT:
A joint prosthesis component for implantation in the end of a bone is provided. The component comprises a collar which holds a stem in a fixed position. The envelope of the bone engaging surface of the collar has a shape and size which corresponds to the shape and size of the cancellous bone at the end of the bone in that the envelope of the collar is more ovoid than round, having a larger diameter which lies medially to laterally and a smaller diameter which lies anteriorly to posteriorly when the component is implanted in the end of the bone. In certain preferred embodiments, the collar, but not the stem, is porous coated.
