[Rupture of the arteria subscapularis following reduction of an anterior shoulder dislocation]

Anterior shoulder dislocations are one of the most common problems seen in an emergency department. Doubtless, immediate reduction is necessary for treatment, a procedure that is extremely rarely accompanied by complications. In these cases early diagnosis and treatment may be limb saving. We report a case with rupture of the arteria subscapularis following reduction of an anterior shoulder dislocation with formation of an axillary hematoma and consecutive paresis of the plexus brachialis. Interdisciplinary operative revision was necessary to remove the hematoma, stop the hemorrhage and for neurolysis of the plexus brachialis. Treatment resulted in a speedy recovery of the patient. Gentle reduction of a dislocated shoulder is a prerequisite for a low complication rate. Contrast-enhanced computed tomography facilitated diagnosis of the hematoma and identification of the bleeding vessel.
