[Fractures of the scapula and injuries of the acromioclavicular joint. The traumatized shoulder and its sequelae].

Fractures of the scapula are rare and mainly result from a severe direct trauma. Most fractures may be treated non-operatively, only severely displaced and unstable fractures of the neck and/or the clavicula, unstable intraarticular fractures of the glenoid or open fractures (especially in combination with neurovascular lesions) should be fixed operatively. A dislocated fracture of the clavicula or glenoid should be approached first ventrally. Displaced fractures of the neck and body may also require an open reduction and fixation through a dorsal approach. Careful preoperative planning and anatomical studies are required to prevent intraoperative damage of innervation and vascularization. Cannulated single screws, 1/3 tubular plates or 3.5 LC-DC plates are recommended for the stable fixation of the scapula, whereas a Bosworth screw or a hook plate are helpful to stabilize the lateral clavicula and the acromioclavicular joint. Postoperative treatment: Temporary immobilization in a Gilchrist or Desault bandage for about 3 to 4 days thereafter careful passive and active mobilization.
