Subclavian Groove[edit]

Diagram of the clavicle showing the subclavian groove.

The subclavian groove is a notable anatomical feature located on the inferior surface of the clavicle, which is the bone that serves as a strut between the shoulder blade and the sternum. This groove is specifically designed to accommodate the subclavius muscle, a small muscle that plays a crucial role in the stabilization of the clavicle.

Anatomy[edit]

The subclavian groove is situated on the inferior surface of the clavicle, extending from the sternal end towards the acromial end. It is a shallow depression that provides a site of attachment for the subclavius muscle. The groove is more pronounced in some individuals, depending on the development of the muscle and the overall morphology of the clavicle.

Function[edit]

The primary function of the subclavian groove is to serve as an attachment point for the subclavius muscle. This muscle originates from the first rib and its cartilage and inserts into the subclavian groove of the clavicle. The subclavius muscle helps to stabilize the clavicle by pulling it downward and forward, which is particularly important during movements of the shoulder girdle.

Clinical Significance[edit]

Injuries or abnormalities involving the subclavian groove can affect the function of the subclavius muscle, potentially leading to issues with shoulder stability. Fractures of the clavicle, which are common due to falls or direct trauma, can involve the subclavian groove and may require careful management to ensure proper healing and restoration of function.

-The Subclavian Groove is a shallow groove found on the upper surface of the first rib. It extends from the [[tubercle]] of the rib to the [[costochondral junction]], and is separated from the [[scalene tubercle]] by a ridge. The groove accommodates the subclavian artery and vein, which supply blood to and from the upper limbs.
-==Clinical Significance==
+=== Anatomy ===
-The Subclavian Groove is of clinical significance due to its proximity to important vascular structures. Damage to the groove, such as through trauma or surgical procedures, can potentially lead to injury of the subclavian vessels. This can result in serious complications such as [[hemorrhage]] or [[thrombosis]].
