A bone fixing device includes an intramedullary nail (1) with a distal end part (2), a proximal end part (3), a center line (4), and a bore (5) that extends perpendicular to the center line (4) in the proximal end part (3) and is provided with a bore axis (6). The bone fixing device further includes a bone plate (10) with a top face (11), a bottom face (12) that is to be in contact with the bone, a continuous, central opening (13) which is located in the central portion of the bone plate (10) and connects the top face (11) to the bottom face (12), and several plate holes (14) that are also continuous and are disposed peripherally around the central opening (13).
