Milling tool for emptying the femoral medullary space, while creating a space for the shaft of a hip prosthesis, which comprises a flexible core and a plurality of conical, rotationally symmetrical milling segments, mounted in superimposed manner on the core and provided with a central through-bore, the milling segments being so connected to the core and/or the milling segments adjacent thereto, that a rotational force applied to the core and/or the upper segment is transferred to the individual milling segments, as well as a hip prosthesis with a conically directed shaft and a ball mounted on the proximal end of the shaft and which comprises a flexible core, a plurality of conical, rotationally symmetrically segments, mounted in superimposed manner on the core and provided with a central through-bore and a device for tensioning the core to bring a stiffening of the shaft formed from the individual segments.
