Abstract

A modular hip prosthesis operable to engage the cortical material in a host femur having a metaphysis and an intramedullary canal. The modular hip prosthesis includes a modular metaphyseal segment which is able to be inserted into the metaphysis of the host femur. The modular metaphyseal segment includes an axial cone portion and a cervical cone portion. The modular hip prosthesis further includes a modular diaphyseal segment which is able to be inserted into the intramedullary canal and being removably secured to the modular metaphyseal segment. Finally, the modular hip prosthesis includes a modular head which is able to engage the modular metaphyseal segment and is detached from the modular diaphyseal segment. Also disclosed is surgical instrumentation for use in implanting a medical device. The surgical instrumentation includes a template having a plurality of scaled markings disposed thereon. The surgical instrumentation also includes a plurality of surgical instruments also having scaled markings disposed thereon. The positions of the scaled markings on the surgical instruments have a correspondence with the position of the scaled markings on the template.
