Thoracic outlet syndrome caused by chronic retrosternal dislocation of the clavicle. Successful treatment by transaxillary resection of the first rib

Abstract

Traumatic posterior dislocation of the sternoclavicular joint is an unusual injury. We report a rare, late complication in the form of a thoracic outlet syndrome. Resection of the first rib resulted in prompt and complete resolution of the symptoms and would appear to be the appropriate treatment, avoiding the complications associated with resection of the clavicle.
