A bone fracture internal fixator for repairing a bone fracture of a femoral neck that allows load to be applied to the associated bone parts evenly, and increases the connecting strength between the femoral head and femoral shaft while minimizing the risk of the femoral head being torn apart by the inner connecting member by increasing the diameter of the inner fixing member. The central axial line of the femoral head is offset from the central axial line of the intramedullary nail placed in the medullary cavity of the femoral shaft. In order to bring the inner fixing member such as a lag screw configured to be inserted through the femoral neck close to the central axial line of the femoral neck, the central axial line of the through hole for receiving the inner fixing member is offset from the central axial line of the intramedullary nail.
