[Surgical treatment of fractures of the clavicle--Indication, surgical technique and results].
46 cases of clavicular fracture (25 of the middle third and 21 of the distal third) are reviewed concerning indications for surgery, surgical technique and postoperative results. In 32 cases surgery was necessary due to dislocation (in 7 cases with a rupture of the coracoclavicular ligaments), 3 times due to a complex trauma of the shoulder joint, 3 times due to a local neurovascular involvement, 3 times due to a delayed fracture healing and 3 times due to a pathological fracture. In two cases an open fracture required osteosynthesis. The most frequent surgical procedure was plate osteosynthesis using the following materials: 3.5 mm LCDC plate, the so called "Balser plate" and the "Ulrich plate", 3.5 mm reconstruction plate, 3.5 mm T-plate and compound plate. In 14 cases autogenous bone grafting was performed. Additional suture of the coracoclavicular ligaments was indicated in 7 patients. In every case early physiotherapy followed the surgical procedure.


RESULTS
in 2 cases an avascular pseudarthrosis emerged after plate osteosynthesis without autogenous bone grafting. In one case a non-union developed due to infection. Moreover we found a loosening of a "Balser plate" and in one patient the development of keloid tissue. The functional outcome according to the Constant score was good. 32 patients achieved 89 out of 100 possible points (average follow up 31 months). In distal clavicle fractures we prefer the use of the "Balser plate" combined with a suture of the coracoclavicular ligaments. Due to the occurrance of delayed fracture healing with pseudarthrosis (2/25) in fractures of the middle third, the indication for surgical treatment has to be discussed. In case of local soft tissue trauma and damage of the periostal blood supply, plate osteosynthesis in combination with autogenous bone grafting should be performed.
