Scapular winging represents a rare phenomenon that most commonly results from nerve damage to either the long thoracic nerve, spinal accessory nerve, or, less commonly, the dorsal scapular nerve. This injury results in an abnormal scapulohumeral interaction during kinetic motion known as scapular dyskinesis. In this case report, the patient presented with scapular dyskinesis and medial scapular winging caused by overhead weight-lifting exercises, and a long thoracic nerve injury was diagnosed. Physicians are encouraged to consider long thoracic nerve damage in a patient with a history of repetitive overhead movements who presents with scapular dyskinesis and the corresponding restriction of overhead arm motions. Potential mechanisms of injury and treatment options are also discussed.
