Scapulothoracic dissociation (SCTD) is a rare clinical entity with fewer than 70 cases reported in English literature. The mechanism of injury is severe rotational force, which causes disruption of the shoulder girdle from the rest of chest wall. Frequently, SCTD produces massive blood loss as it involves major fractures of the upper extremity, disruption of muscle, brachial plexus, and vascular damage. This case report demonstrates classical radiological findings of SCTD with brachial plexus injury but with no associated vascular damage.
