There is only a layer of skin around the clavicle and no abundant soft tissue, which slightly causes a change in the bone structure and results in asymmetry. To determine the specific cause of clavicle asymmetry, if the clavicle asymmetry is caused by scoliosis, or rickets during childhood, or thoracic developmental deformity, it can only be corrected by surgery. If the clavicle asymmetry is caused by shoulder dislocation, acromioclavicular joint dislocation, or clavicle fracture, you should go to the hospital for a radiographic examination to see the specific severity of the underlying lesion. If it is relatively mild, conservative treatment with external fixation will protect it, but if it is serious, surgery is needed to correct it. If it is caused by poor posture of the shoulder joint in daily life and poor posture over time, you should pay attention to sitting straight, standing straight, and doing functional rehabilitation exercises of the shoulder joint to restore the balance of the muscles, and then it can be corrected.
