A device for fixation of a bone fracture comprises an appliance (1) and fixing elements in the form of pins (2). The appliance (1) has predrilled holes (4) in a distal end portion (1d) and predrilled holes (4) in a proximal end portion (1e) for insertion of the pins (2) through said holes (4). The predrilled holes (4) have a diameter which is adapted to the diameter of forward portions (2a) of the pins (2), the pins (2) have rearward threaded portions (2b) in which the outside diameter of the threads is larger than the diameter of said forward portions, the material of the appliance (1) is such that the threaded rear portions (2b) of the pins (2) can be screwed into it and the forward portions (2a) of the pins are driven into the bone (3) with the fracture (3a) on both sides of the fracture, and the predrilled holes (4) are oblique relative to a longitudinal axis (A) of the appliance (1) such that distal pins (2) cross proximal pins (2) and such that the distal and proximal pins (2) all cross the bone fracture (3a). |
