The clavicle is the bone that connects the upper extremity to the trunk, with a flattened distal end, convex to the dorsal side, and an S-shaped overall appearance, which mainly plays a supporting role and a link between the trunk and the upper extremity. The clavicle plays an important role in the activities of the chest, upper limbs, and shoulder joints because there are many muscles attached to the clavicle, such as the neck muscles, shoulder muscles, and chest muscles, which play a role in connecting the upper limbs, neck, and chest activities. The clavicle is mainly composed of the sternoclavicular and acromioclavicular joints, which play a key role in the significant movement of the shoulder and the micromovement of the chest. The clavicle is superficial, so it is easy to fracture clinically, and after the fracture, it is easy to feel the bone rubbing and fracture deformity.
