Abstract Milling tool for emptying the femoral medullary space, while creating a space for the shaft of a hip prosthesis, which comprises a flexible core ( 10 ) and a plurality of conical, rotationally symmetrical milling segments ( 12 ), mounted in superimposed manner on the core ( 10 ) and provided with a central through-bore, the milling segments ( 12 ) being so connected to the core ( 10 ) and/or the milling segments ( 12 ) adjacent thereto, that a rotational force applied to the core ( 10 ) and/or the upper segment ( 12 ) is transferred to the individual milling segments ( 12 ), as well as a hip prosthesis with a conically directed shaft and a ball ( 16 ) mounted on the proximal end of the shaft and which comprises a flexible core ( 10 ), a plurality of conical, rotationally symmetrical segments ( 12 ), mounted in superimposed manner on the core ( 10 ) and provided with a central through-bore and a device ( 14 ) for tensioning the core ( 10 ) to bring about a stiffening of the shaft formed from the individual segments ( 12 ).
A milling tool for emptying a femoral medullary space to form a space for a shaft of a hip prosthesis, comprising: a flexible core ( 10 ), a plurality of conical, rotationally symmetrical milling segments ( 12 ) mounted in superimposed manner on said flexible core ( 10 ) and having central through-bores, which transmit a rotational force applied to said core ( 10 ), and a tensioning device ( 14 ) that tensions said core ( 10 ).
