Abstract A recently presented, new device for fixation of forearm-bone fractures was investigated mechanically. The fracture compression obtained with the device was measured and the rigidity of the fixations studied for flexural and torsional loads. As experimental specimens, cylindrical oak rods instead of bone shafts were used. The rods were prepared with two types of fractures, transverse cuts and V-cuts. The investigation led to an improved fixation device, giving higher fracture compression and better fixation rigidity. Comparison with a four-hole, semitubular AO (ASIF) plate for fracture fixation revealed that the semi-tubular plate gives better rigidity and higher total compression force, although this force is not necessarily evenly distributed over the fracture, as would be preferred. The main advantage of the new device is clinical, with less trauma to the bone at application, and shorter operation times than with established methods.
