The clavicle is located at the base of the neck, connects the scapula to the sternum, crosses the anterior and superior part of the thorax on both sides, is located under the skin, and is palpable over its entire length. The clavicle is located in the anterior superior part of the thoracic cavity, transverse to the junction of the neck and chest, connecting the scapula to the sternum, and is palpable on the body surface over its entire length, making it a distinctive bony landmark. The clavicle is bounded by the sternum, one on each side. Clavicle is the upper limb and the trunk of the connection and support device, was “S” shaped, the distal 1/3 for the flattened convex dorsal, conducive to muscle and ligament attachment, pulling, and its distal end and the acromion to form the acromioclavicular joint, and there is a rostral clavicular ligament fixation of the clavicle. The proximal 1/3 of the clavicle is rhombic and convex to the ventral side, forming the sternoclavicular joint with the sternal handle. The junction of the middle 1/3 and outer 1/3 of the clavicle is the weakest part of the clavicle, so it is easy to cause clavicle fracture when it is subjected to violence or when it falls and lands on the shoulder or hand. Clavicle has important clinical significance to the organism, so when abnormal manifestations need to go to the hospital in time for examination and treatment, so as not to delay the condition.
