Scapulothoracic dissociation is a rare entity that consists of disruption
of the scapulothoracic articulation. The mechanism of injury is probably
traction caused by a blunt force to the shoulder girdle. This lesion is
characterized by massive soft-tissue swelling of the shoulder; lateral
displacement of the scapula, measured radiographically; an injury to bone
(an acromioclavicular separation, a displaced fracture of the clavicle, or
a sternoclavicular disruption); a severe neurovascular injury; and a
variety of upper and lower-extremity fractures. We treated fifteen patients
who had this lesion, most of whom had several associated injuries. Three
patients died: two from exsanguination and one from a cardiac arrest. In
most patients, the damaged artery was repaired and the brachial plexus was
explored. All of the twelve patients who had a complete brachial-plexus
injury were left with a flail upper extremity. Most patients refused
amputation.
