A femoral rasp for preparing an intramedullary canal for receiving the stem of a femoral hip prosthesis comprises a body section generally divided into a wide proximal portion and a substantially longer narrow distal portion. The body section has a shape that generally corresponds to the stem of a femoral hip prosthesis to be inserted into the prepared cavity. A plurality of spaced apart cutting teeth are located on selected portions of the outside surface of the body section for removing cancellous tissue and bone. A smooth surface on the lateral face of the body section at the free end of the distal portion prevents violation of the lateral cortex upon insertion of the body section into the intramedullary canal. Removal of the body section and insertion of the hip prosthesis results in a glove fit between the stem of the prosthesis and the cavity formed by the femoral rasp.
