Anterior fracture-dislocation of the glenoid

Abstract

Fractures of the scapula represent less than 1% of all skeletal fractures. This case report describes an unusual case of fracture of the scapula with complete anterior dislocation of the glenoid and pillar of the scapula occurring in the right (dominant) shoulder of a 24-year-old male after a high-energy trauma (motorcycle accident). This fracture is very rare and did not fit in any known classifications (Ideberg, Euler and Rüedi, AO/OTA). The fracture was treated with open reduction and internal fixation through a double approach (deltopectoral and superior). A posterior cruciate ligament (PCL) guide was used to maintain the reduction and insert first a K-wire and then a cannulated screw. We discuss here the mechanism of injury, fracture pattern and the appropriate surgical approach and management in case of such an exceptional anterior fracture-dislocation of the glenoid.
