Abstract:
An improvement in a prosthetic implant having a proximal portion for enabling replacement of an element of a natural joint, and a distal portion for securement within a recess in the natural bone adjacent the natural joint, the recess including an internal surface having a transverse extent, the improvement comprising:an elongate core extending axially along the distal portion of the prosthetic implant for reception within the recess in the natural bone, the core having an external surface with a transverse dimension less than the transverse extent of the internal surface of the recess for confronting the internal surface of the recess in the natural bone with the external surface spaced from the internal surface when the core is located within the recess; andat least one allograft body along the core, over the external surface of the core, for interposition between the core and the internal surface of the recess, the allograft body having a generally tubular configuration including an inner securement surface gripping the core to secure the allograft body in place upon the core and an outer locator surface for engaging the internal surface of the recess to locate the core transversely within the recess.
