Winged scapula, also known as scapular winging, is a condition characterized by protrusion or prominence of the medial border of the scapula away from the rib cage. This creates a visible "wing-like" appearance of the scapula on the back and may cause difficulty in moving the arm and shoulder. Winged scapula is caused by weakness or paralysis of the serratus anterior muscle. It can be a result of nerve damage, trauma, muscular dystrophy, or other neuromuscular disorders. Treatment for winged scapula depends on the underlying cause. Physical therapy, exercises, and stretching can help to strengthen the muscles and improve range of motion. In some cases, surgery may be necessary to repair or reconstruct damaged muscles or nerves.
