ABSTRACT:
A set of modular components from among which an implantable orthopedic hip prosthesis can be assembled. First and second implantable orthopedic femoral hip stem prosthesis each have a neck, the neck having a male conical taper surface. An implantable orthopedic femoral head prosthesis has a female conical taper surface. The respective male and female conical taper surfaces are sized and configured for mutual taper-locked interconnection if engaged, but at least one of the first and second implantable orthopedic femoral hip stem prosthesis is keyed in combination with the implantable orthopedic femoral head prosthesis to prevent engagement of the respective male conical taper surface with the female conical taper surface.
