A 27-year-old male presented to the emergency department with severe bilateral shoulder pain and inability to abduct his arms. The pain began suddenly while asleep, however the patient did not remember falling asleep. Examination was notable for tongue laceration, absent active range of motion of bilateral shoulders and diffuse tenderness to palpation with visible deformity at each shoulder. Imaging demonstrated bilateral posterior glenohumeral joint dislocations with severe bilateral reverse Hill-Sachs deformities. Successful closed reduction of the right glenohumeral joint was performed by orthopedics, however the left-sided reduction attempt failed. He was made non-weight bearing at bilateral glenohumeral joints and placed in a shoulder sling on right and immobilizer on left. He received bedside physical and occupational therapy while admitted ensuring maintenance of ADL capacity within weight-bearing and ROM restrictions. Given the non-specific injury history, tongue laceration and usage of Olanzapine for schizophrenia which lowers seizure threshold, the dislocations were suspected secondary to seizure.
