What is being described?-Not a true joint; a sliding junction between the deep aspect of the scapula and thoracic rib cage at the levels of ribs 2 through 7. Made up of the scapula (shoulder blade) and its articulation with the ribcage and enables movement of the scapula against the chest wall during movements of the upper limb. Although the anterior surface of the scapula is concave and the posterior surface of the thoracic cage is convex, the concave/convex rules of movement do not apply.
scapulothoracic articulation
The above description is referring to the Scapulothoracic Joint. This is not a true joint as mentioned, but rather a sliding junction between the scapula (shoulder blade) and the thoracic rib cage at ribs 2 through 7. It enables the movement of the scapula against the chest wall during the movement of the upper limb. Although the concave/convex rules of movement do not apply here, it is an important part of the body’s overall functional movement and stability.
