Do you know that the collarbone is the first bone to begin the process of ossification (laying down of minerals onto a preformed matrix) during development of the embryo, during the fifth and sixth weeks of gestation. And it is one of the last bones to finish ossification at about 21–25 years of age.
Do you know that the collarbone lies almost horizontally along the top of your chest at the front of your shoulder? If your collarbone doesn’t appear to be horizontal or near parallel with the ground, you likely have some tightness pulling your clavicles out of alignment. The more angled one or more clavicle is, the more out of alignment it is.
What could happen if there is a limitation at the clavicular joints? A limitation here may lead to subsequent limitation in GH motion and consequently disrupt the line of pull from the rotator cuff and other ST muscles. Sequentially, this has the potential to lead to muscle weaknesses, various GH joint pathology, scapular dyskinesia, and other chronic shoulder conditions.
The brachial plexus and the subclavian vein traverse the thoracic aperture, run across the first rib and below the clavicle in the direction of the axilla, and continue into the arm. If the subclavius is affected, the brachial plexus or subclavian vein can be pinched because this muscle brings the clavicle and the first rib close to each other. The result can be different circulatory syndromes of the arm, such as Sudeck syndrome, Dupuytren contracture, or medial and lateral epicondylitis. These vessels and nerves can also be pinched as a result of fascial hypertonicity in the thoracic aperture. Heart irritation, thoracic outlet syndrome, and chronic sinusitis could be possible consequences.(Visceral Manipulation in Osteopathy byEric U. Hebgen)
On the left side, the thoracic duct drains into the venous angle formed by the internal jugular vein and the subclavian vein. The phrenic nerve runs along the anterior scalene muscle caudally and enters the thoracic aperture at the medial end of the clavicle. The vagus nerve takes a similar path into the thorax near the sternal end of the clavicle. If these structures are irritated by high fascial tension, this can affect the organs in the thorax or abdomen: it can, for example, impair lymphatic drainage from the abdomen, the function of the diaphragm, or the vagus supply area.
