Bilateral Divergent Shoulder's Fracture Dislocation Case in an Ischemic Stroke Patient.

INTRODUCTION: The literature review revealed that nowadays only about 15 cases of bilateral shoulder dislocation associated with the fracture of the upper end of the humerus have been published. The triad of lesional mechanism designated by the triple syndrome E composed of epilepsy, electrocution, and external trauma was the circumstances noted in which these fractures dislocations occur with migration of the two humeral heads either forward or backward.

CASE REPORT: An architect of 36-year-old, right-handed, was admitted in emergency department for loss of knowledge of progressive installation. At admission the blood pressure, pulse, and temperature were normal. There was a right hemiparesis predominantly in brachiofacial side and an aphasia. After intensive resuscitation measures, the cerebral computed tomography scan revealed a left temporoparietal hypodensity area affecting the middle cerebral artery superficial territory with a mass effect compatible with acute ischemic stroke. During the hospitalization, episodes of generalized tonic-clonic convulsions appeared with a fever at 39°C and a leukocytosis at 35 thousand on the 5th day. These convulsions caused on the right shoulder an anterior dislocation under coracoid, associated with a fracture of the greater tubercle and on the left shoulder, posterior dislocation with much displaced comminuted articular proximal humeral fracture. We did reduction by external maneuvers for the right shoulder and open reduction with internal fixation by anatomical plate of left shoulder lesions. In the immediate aftermath of surgery, he presented episodes of agitation which led to the dismantling of the left shoulder fixation. He was evacuated to the North Country where an ablation of the left shoulder material and stabilization by locked plate were carried out. The sequelae were marked by the occurrence of an osteomyelitis with osteolysis of the entire upper right humerus extremity. It will require an inverted prosthesis.

CONCLUSION: The surgical treatment must be done by a solid assembly and consultation with neurologists and anesthetists is essential. This multidisciplinary management could prevent any convulsive postoperative seizures that would risk sacrificing all therapeutic efforts.
