A bursa on the anterior surface of the subscapularis where it slides against the serratus anterior and the chest wall during scapular protraction and retraction. This is distinct from the subscapular bursa at the glenohumeral joint and addresses friction at the scapulothoracic articulation level.
This bursa is involved in scapulothoracic bursitis (snapping scapula syndrome), where the subscapularis-chest wall interface becomes inflamed producing a painful grinding sensation with shoulder movement. Ultrasound-guided injection between the subscapularis and serratus anterior addresses this component. It is distinct from the more commonly described superomedial angle bursae that are the primary cause of scapulothoracic crepitus.
Inflammatory or mechanical irritation at the subscapularis-chest wall interface producing audible or palpable crepitus and pain with scapular protraction, treated with injections and scapular stabilisation exercises.
