Scapular Winging
Abnormal protrusion of the scapula from the chest wall due to weakness or paralysis of the serratus anterior or other scapular stabilizing muscles.
Full Definition
Scapular winging is a clinical condition characterized by the abnormal prominence or protrusion of the medial border of the scapula away from the chest wall. This occurs most commonly due to weakness or paralysis of the serratus anterior muscle, often resulting from long thoracic nerve injury. In athletic populations, scapular winging can develop from repetitive overhead activities, direct trauma, or neuromuscular fatigue. The condition significantly affects shoulder blade stability and can compromise overhead athletic performance. Clinical assessment involves observing scapular position during arm elevation and resistance testing.
Usage
Usage note: Distinguish from general scapular dyskinesis, which encompasses broader movement abnormalities.
