“…In 15.7% of the cases, the diagnosis of bilateral anterior dislocation was not immediate, but less than three weeks, and it was not traumatic in these cases (10). Among 30 case reports of bilateral shoulder dislocations, nine cases (30%) had an associated injury (11).…”

Introduction: Shoulder dislocation is the most common presentation of joint dislocation in emergency department (ED). Bilateral shoulder dislocation seldom happens and often is posterior type. It usually occurs due to seizure and electric shock. Trauma is among the common causes of bilateral anterior shoulder dislocation. Here, we present a case of bilateral anterior shoulder dislocation due to seizure attack. Case Presentation: A 21-year-old man presented to ED with complaint of bilateral shoulder pain and restricted range of motion. The patient was under therapy for epilepsy, but discontinued his therapy in recent weeks. He had a seizure attack while sleeping and thereafter he was unable to move his arms. Neurovascular examination of both upper extremities was normal. Shoulder X-ray images revealed bilateral anterior dislocation. Reduction was performed in ED with sedation by adduction and external rotation method. Neurovascular systems were rechecked and reduction was confirmed by radiologic images. Both shoulders were immobilized by sling and swathe, and patient discharged from ED with follow-up recommendation. Conclusions: Bilateral anterior shoulder dislocation is rare. It could be undiagnosed, especially when there is no clear history of major trauma. By awareness of such unusual possibility, early diagnosis, treatment, and reduction can provide desirable outcome.

“…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).…”

“…In addition, most reported cases have occurred following trauma, with few reports of bilateral anterior dislocation occurring secondary to seizure activity 1 4 5 6 7.

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 mechanism of posterior dislocation is that the internal rotators of the humerus (latissimus dorsi, pectoralis major and subscapularis) which are more powerful than the external rotators (infraspinatous and teres minor) cause an excessive adduction and internal rotation during the seizure which results in a posterior dislocation of the humeral head [5]. Therefore, trauma is a more usual cause than seizures during bilateral anterior dislocation [6]. Many authors have suggested that bilateral anterior dislocation after an epileptic seizure cannot occur during muscular contractions, but following trauma of the shoulders striking the ground after the fall [7,8].…”

Background: The unilateral glenohumeral dislocation is the most frequent form of joint dislocation, but the bilateral dislocation is very uncommon. Although the expected form of dislocation after an epileptic seizure is the posterior form, the bilateral anterior form is much rarer. Case Report: A 30 year old man presented to emergency department with pain and deformity of both shoulders following fall due to convulsive seizure. On physical examination at the emergency, we noticed a total loss of function of both upper limbs fixed in abduction that was irreducible. Standard plain X-ray assessment of both shoulders confirmed the diagnosis of bilateral anterior-internal dislocation. Conclusion: In unilateral shoulder dislocations, the incidence of posterior dislocations is markedly less than that of anterior shoulder dislocations. The opposite is true of bilateral shoulder dislocations. Bilateral anterior shoulder dislocations after an epileptic fit is very uncommon.
