the proximal aiming appliance not shown subsequently compression screw 24 is entered in proximal thread 6 of the proximal portion until it contacts fixing screw 18 by its distal end 25 as the compression screw is now further entered the proximal fragment of the bone is displaced relative to the nail until the fracture is closed and an interfragmentary compression is obtained compression screw 24 further comprises a shaft portion 26 which is followed by an externally threaded portion 27 of greater diameter as well as a hexagon socket 28 as an essential extension of the field of applications of the intramedullary nail according to the invention more particularly for an antegrade or a retrograde fixation an insert 7 is provided which may either be hollow or solid in design insert 7 according to the embodiment shown in fig1 and 5 comprises a through going longitudinal bore 34 and two guiding bores 29 which are inclined with respect to the longitudinal axis more than two guiding bores being possible but at least one such bore being provided in this case the external diameter of cap screw 21 approximately corresponds to the external diameter of insert 7 thus allowing its fastening a subsequent displacement of the insert in the longitudinal.
