Abstract
An apparatus for the preparation of a cement-free implantation of a prosthesis is provided. The prosthesis has a distal part corresponding to a diaphysial region of the femur, a proximal part corresponding to a metaphysial region of the femur, and an intermediate region which corresponds to a metaphysial-diaphysial region. The apparatus includes a rasp of modular design including a conical distal part and first and second proximal parts of substantially different basic shapes and heights. The apparatus also includes a releasable connection means at the distal part for connecting a proximal part to at least one distal part. The apparatus also includes a neutral intermediate element mountable on the distal part of the rasp for driving it and for measuring its degree of recessing on a graduated scale.
