Scapular Winging
Definition
A condition where the medial border or inferior angle of the scapula protrudes posteriorly from the rib cage. The scapula appears to 'wing' outward instead of sitting flat against the thorax. Can be caused by serratus anterior weakness (long thoracic nerve palsy), trapezius dysfunction, or thoracic kyphosis pushing the scapula away from the rib cage.
Clinical Significance
Scapular winging compromises the scapula's ability to upwardly rotate, posteriorly tilt, and externally rotate during overhead movement. This narrows the subacromial space and contributes to shoulder impingement, rotator cuff tendinopathy, and overhead pressing pain. The cause is frequently thoracic spine position rather than isolated scapular muscle weakness.
How AKMI Assesses This
AKMI assesses scapular position at rest (medial border distance from spine, inferior angle protrusion) and during dynamic movement (push-up plus, overhead reach). The assessment cross-references with thoracic kyphosis and rib cage position.
