Queston #17051Note

Scapular winging is most commonly due to damage to the long thoracic nerve, leading to weakness of the serratus anterior muscle. Scapular winging can also occur secondary to damage to the dorsal scapular nerve, which innervates the rhomboid muscles, and the spinal accessory nerve, which innervates the trapezius muscle. Additionally, patients with facioscapulohumeral muscular dystrophy can also present with scapular winging due to significant weakness of the trapezius and rhomboid muscles
