The sternoclavicular articulation is a double arthrodial joint. The parts entering into its formation are the sternal end of the clavicle, the upper and lateral part of the manubrium sterni, and the cartilage of the first rib, visible from the outside as the suprasternal notch. The articular surface of the clavicle is much larger than that of the sternum, and is invested with a layer of cartilage, which is considerably thicker than that on the latter bone.

—The anterior sternoclavicular ligament is a broad band of fibers, covering the anterior surface of the articulation; it is attached above to the upper and front part of the sternal end of the clavicle, and, passing obliquely downward and medialward, is attached below to the front of the upper part of the manubrium sterni.
It is attached, above, to the upper and posterior border of the articular surface of the clavicle; below, to the cartilage of the first rib, near its junction with the sternum; and by its circumference to the interclavicular and anterior and posterior sternoclavicular ligaments.
Monograph 20 ~ PRIORITY APPRAISAL FOLLOWING ANTERIOR THORAX TRAUMA (8368 words)
Soft-tissue injuries of the extraspinal thoracic region often involve the sternoclavicular joints, sternocostal joints, anterior and posterior musculature and ligaments, and tissues of the spinocostal (costovertebral and costotransverse) joints.
Because of the structural-functional reciprocity of the clavicles with the sternum, pain and biomechanical disorders of sternoclavicular mobility and malalignment are typically referred to the shoulder.
Sternoclavicular sprains vary from minor to complete dislocation, displacing posteriorly (retrosternal), posterior-medial to overlay the manubrium, or anterior-inferior to overlap the 1st rib.
