Shoulder dislocation can occur following seizures resulting in large bony abnormalities of the humeral head and/or the glenoid, and persistent instability. Existing epilepsy along with the other comorbidities make the diagnosis and management extremely challenging. Severe bone loss in the glenoid and the humeral head and repetitive trauma from frequent conclusive episodes are essential parts of the issue. Pain and limitation of the range of motion are the predominant symptoms following dislocation due to seizures. Plain radiographs, computed tomography and magnetic resonance arthrography are the diagnostic tools used to fully diagnose the problem. Surgical treatment methods mainly include soft tissue procedures and bone augmentation procedures depending on the amount of bone defects of the glenoid and humerus. In cases with osteoarthritis, arthroplasty is also an option, while glenohumeral arthrodesis is used as a salvage procedure.
