Test prosthesis system (1) for the insertion of a so-called press-fit-effect femur prosthesis for cement-free implantation into a femur bone (2) in a region (3) in which the press fit effect is preferably obtained and which corresponds to a diaphysial region, the height of which differs depending on the morpho type, characterized in that it consists of a set of at least two shafts (4, 5) each of which has a conical distal region (4, 5) with the same cone angle but a different diameter (D) the first conical region with a smaller maximum diameter D having a proximal region congruent to (i.e. overlapping in size and shape) with a distal region of a second conical region of a second shaft with a larger maximum diameter of the conical region. <IMAGE>
