“…described a mechanism of the anterior dislocation during seizure and support that bilateral dislocation may be from trauma of the shoulders striking the floor after a collapse rather than due to the muscle contractions. Loss of consciousness after a seizure will not allow the patient to react and reflexly protect one of his arms by exposing the other [9]. We believe that this mechanism is responsible in both cases we described.…”

Anterior glenohumeral dislocation is the most common lesion of dislocations that appears in emergency department. Bilateral anterior shoulder dislocation is a rare injury and in majority of cases originates from trauma. We review two cases (a male, 70 years old and a female, 68 years old) with a simultaneous bilateral anterior dislocation of the shoulder after an epileptic seizure during daily activities. Dislocations were diagnosed after detailed clinical and imaging examination. Under general anesthesia closed reduction with Kocher technique was applied in both patients. A percentage more than 10% of the bilateral anterior dislocation may missed out in the first diagnosis which leads to serious morbidity and loss of function in patients. The aim of this study is to describe two rare cases with simultaneous bilateral anterior glenohumeral dislocation.

“…While the mechanism of bilateral posterior dislocation following seizure is well known, with powerful tonic contraction of the shoulder girdle musculature resulting in the stronger internal rotators causing adduction and internal rotation, the mechanism of bilateral anterior shoulder dislocation following seizure is less predictable. It has previously been suggested that bilateral anterior dislocations may occur as a result of the trauma associated with loss of consciousness during a seizure, rather than the seizure activity itself 1 8. Buhler et al reported in their series (26 shoulder dislocations post seizure, 13 anterior and 13 posterior), that recurrent shoulder instability following dislocation precipitated by seizure is much more common in anterior shoulder dislocations (12/13) rather than posterior (2/13).…”

Bilateral anterior shoulder dislocation is a rare clinical entity with few case reports and limited series published in the literature. Bilateral shoulder dislocations are rare and of them, most are posterior. We present a highly unusual case of bilateral, atraumatic, anterior shoulder dislocation with concomitant comminuted greater tuberosity fracture on the right side, secondary to seizure, in a patient without known epilepsy, induced by oral chloroquine medication. We demonstrate the treatment approach that led to a satisfactory clinical outcome, evidenced by radiological union, clinical assessment and Patient Reported Outcome Measure data, following non-operative management of both shoulders. The unusual mechanism for anterior shoulder dislocation, the asymmetric dislocation pattern and peculiar precipitant for the causative seizure all provide interesting learning points from this case.

“…The injury can be trivial, especially in elderly as in this case ( 9 ). Besides traumatic causes, bilateral anterior shoulder dislocation can follow hypoglycemic convulsion ( 11 ) or epileptic seizure ( 14 , 17 , 21 ). The posterior dislocations are more common after seizure since the contraction of the relatively weak external rotators and the posterior fibers of the deltoid are overcome by the more powerful internal rotator.…”

“…The posterior dislocations are more common after seizure since the contraction of the relatively weak external rotators and the posterior fibers of the deltoid are overcome by the more powerful internal rotator. The succeeding adduction and internal rotation usually causes the humeral head to dislocate posteriorly ( 21 ). Bilateral anterior dislocation following a seizure may be from the trauma of the shoulders striking the floor after the collapse rather than due to the muscle contractions ( 21 ).…”
