FIELD: medicine.SUBSTANCE: group of inventions refers to medicine. According to the first version, an intramedullary nail for the femoral bone comprises a pin having a proximal segment, a distal segment, a medial side, a lateral side and a long axis extending in the proximal and distal directions. The proximal segment has a non-circular cross-section perpendicular to the long axis. A reparative incision is made on the proximal segment and directed to the femoral head and neck. In the reparative mode, at least one element is inserted into the above incision. An antegrade incision is arranged on the proximal segment and directed towards the lesser trochanter. In the antegrade mode, at least one element is inserted into the above incision. A reparative incision extends from the medial side of the nail to its lateral side. The antegrade incision is radially displaced in relation to the reparative incision. The central axis of the antegrade incision does not transect the long axis of the nail. The intramedullary nail for the femoral bone according to the second version comprises a pin having a proximal segment, a distal segment, a medial side, a lateral side and a long axis extending in the proximal and distal directions. A reparative incision is made on the proximal segment and directed to the femoral head and neck. In the reparative mode, at least one element is inserted into the above incision. The antegrade incision is arranged on the proximal segment and directed towards the lesser trochanter. In the antegrade mode, at least one element is inserted into the above incision. The distal incision is made on the distal segment. Each of the above incisions, namely the reparative, antegrade and distal incisions have the central axis. The central axis of the antegrade incision lies in the antegrade plane parallel to the long axis. The central axis of the distal incision lies in the antegrade plane or in a plane parallel to the antegrade plane. The central axis of the repara
