Traumatic lateral displacement of the scapula: a radiographic sign

of neurovascular disruption. Oreck-SL; Burgess-A; Levine-AM J-Bone-Joint-Surg-Am. 1984 Jun; 66(5): 758-63 Scapulothoracic dissociation, as manifested by lateral displacement of the scapula and acromioclavicular separation, is a previously unreported injury in which there is a complete disruption of the scapulothoracic articulation without an overlying partial or complete amputation through the soft tissue. Associated with the disruption of the scapulothoracic articulation are injuries to the brachial plexus and the subclavian artery and vein; multiple open and closed fractures of the ipsilateral upper extremity are often present also. In the patient with severe multiple injuries, scapulothoracic dissociation may not be recognized immediately, with potentially fatal consequences. In this paper we present the cases of three patients with radiographic and pathological evidence of scapulothoracic dissociation and review the literature on related injuries.
