[The osteosynthesis of fractures of distal radius with the AO/ASIF Titanium Pi Plate].

The AO/ASIF Titanium Pi Plate has been developed for dorsal plating of fractures of the distal radius. It is designed by reflection of the anatomy, to ensure stability of the angle using a juxtaarticular band and to minimize tissue reaction by low profile design. The aim of this study was to evaluate the subjective and objective outcome of 61 consecutively operated patients after a minimum of 12 months (12-29 months) postoperatively. There were 3 A2, 23 A3, 1 B1, 12 C1 and 22 C2 fractures (AO-Classification). The subjective results were good to very good. The range of motion showed over 80% compared to the uninjured side. Overall, there were no ruptures of tendons and 18% irritations. Extension, ulnar abduction and force were significantly better in patients in which the plate has been removed. In this collective the tendon irritations were only 3.8%. With the AO/ASIF Pi Plate good subjective and objective results can be achieved. The indication for removal of the plate should be given generously.
