The system and instrumentation of this invention provides a torque wrench adapter for the femoral rasp and for the hip stem implant. Each adapter includes a shaft for connecting a motion indicator thereon. The motion indicator includes a port for accepting the shaft of either the rasp adapter or the implant adapter and an indicator needle which is linked through spring mechanisms to shiftable leg. In use, the leg is anchored at one end to the femur such that the leg moves with the femur and relative to the indicator housing which causes a deflection in the indicator needle to apprise the surgeon of small movement of either the rasp or the implant relative to the femur.

Proximal portion of a femoral hip stem prothesis

A femoral component for a hip prosthesis includes a proximal end shaped in an anatomic manner to form asymmetrical sides. In particular, a lateral side forms an acute angle with an anterior side and a medial side forms an arcuate surface.
