[Paresis of the brachial plexus after anterior shoulder luxation : Traumatic damage or compression due to hematoma?] / Parese des Plexus brachialis nach vorderer Schulterluxation : Traumatische Schädigung oder hämatombedingte Kompression?

After traumatic anterior shoulder dislocation and self-reduction, the patient initially showed an inconspicuous clinical course. At the time of presentation in the emergency room the upper limb neurological status was reported to be normal. After discharge, paresis of the brachial plexus of the left arm occurred within 8 h. A subsequently performed computed tomography (CT) scan revealed a hematoma close to the brachial plexus, which was treated by surgical decompression and resulted in symptom relief. This case report describes a rare but significant complication after anterior shoulder dislocation, which should not be underestimated in the setting of a surgical emergency admission.
