Surgical instruments for hip revision
First Claim
1. A set of surgical instruments for use in implanting a hip prosthesis in a host femur having a neck portion, said hip prosthesis including a diaphyseal segment and a metaphyseal segment, said set of surgical instruments comprising:
- a distal canal reamer operable to ream a cavity in said host femur for receiving said diaphyseal segment of said hip prosthesis;
a metaphyseal reamer operable to ream a cavity in said host femur for receiving a portion of said metaphyseal segment;
a femoral neck reamer operable during lateral displacement thereof to ream said neck portion of said host femur for receiving a portion of said metaphyseal segment said femoral neck reamer having an outer sleeve; and
a femoral neck cutting guide operable to be used in conjunction with said femoral neck reamer to ream said neck portion, said femoral neck cutting guide including a medially extending alignment arm being operable to guide lateral displacement of said femoral neck reamer.

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.
