[Plate osteosynthesis of the diaphyseal humerus shaft. Indications--risks--results].

Fractures of the shaft of the humerus can be treated conservatively with very good results. In certain situations operative treatment is mandatory. Between 1984 and 1989 25 diaphyseal upper arm fractures were treated operatively, mostly via plate osteosynthesis. The indications for operation in the first place were primary nerve lesions, open fractures and patients with polytrauma for easier nursing. In 24 cases very good and good functional results were achieved. Nevertheless two transitory paresis of the radial nerve due to the operation are mentioned. Possibilities and limits of the conservative and operative treatment of upper arm fractures are discussed.
