1 The Scapulothoracic (ST) âjointâ is not a true anatomic joint as it has none of the usual joint characteristics (union by fibrous, cartilaginous, or synovial tissues). Any movement of the scapula on the thorax must result in movement at either the AC joint, the SC joint, or both; that is, the functional ST joint is part of a true closed chain with the AC and SC joints and the thorax.
Rather, the scapulothoracic articulation is formed by the convex surface of the posterior thoracic cage and the concave surface of the anterior scapula. The scapula is a flat bone, with the gliding surfaces formed by the subscapularis and the serratus anterior.
