The present invention relates to a device for fixation of a bone fracture. The device comprises at least one appliance (1) for placing close to the bone fracture, and fixing elements in the form of pins (2) which are intended to be locked to the appliance (i) in order to fix the bone fracture (3). With the object of allowing correct positioning of the appliance and pins and thereafter driving the pins into correct positions for optimum stable fixation of the bone fracture, the appliance (1) is provided with predrilled holes (4) whose diameter is adapted to the diameter of forward portions (2a) of the pins (2) so that said forward portions can be inserted through the holes until they come up against the bone (3) with the fracture (3a) on which the appliance is used, which pins (2) have, to the rear of said forward portions (2a), threaded portions (2b) in which the outside diameter of the threads is larger than the diameter of said forward portions, and the material of which the appliance (1) is made 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 can thereby be driven into the bone (3) with the fracture (3a) on both sides of the fracture.
