The Costal Tuberosity of Clavicle is a specific anatomical feature of the clavicle, also known as the collarbone. It is located on the inferior surface of the lateral end of the clavicle, and serves as the attachment point for the costoclavicular ligament.

Anatomy

The costal tuberosity of the clavicle is a roughened area on the inferior surface of the lateral end of the clavicle. It is located medial to the conoid tubercle and is larger and more prominent. The costal tuberosity is the point of attachment for the costoclavicular ligament, which connects the clavicle to the first rib.

Function

The primary function of the costal tuberosity is to serve as the attachment point for the costoclavicular ligament. This ligament plays a crucial role in stabilizing the sternoclavicular joint, which is the joint between the sternum (breastbone) and the clavicle.

Clinical Significance

Injuries or conditions that affect the costal tuberosity or the costoclavicular ligament can lead to instability or dysfunction of the sternoclavicular joint. This can result in pain, limited range of motion, and other symptoms.
