Abstract
A prosthesis system consisting of an endoprosthesis with a shank which is to be introduced into the medullary canal of a bone, and of a rasp ( ) which is similar in shape to the shank and is used to prepare a cavity for receiving the shank. Along much of its length, the rasp has an untoothed profile part ( ) which, instead of excavating the spongy bone substance, compacts the latter and thus ensures a secure fit of the prosthesis. In the area corresponding to the untoothed area of the rasp ( ), the prosthesis shank preferably has a rib which cuts like a wedge into the compacted spongy substance.
