The clavicle is large on one side and small on the other, which is a developmental problem. The clavicle is connected to the sternoclavicular and acromioclavicular joints, which are the link between the chest and the upper extremities, and if there is no problem with the movement of the joint, there is no need to worry. Generally, if there is pain, X-ray examination is required for symptomatic treatment. If there are no symptoms and it is simply a developmental problem, it is recommended that observation should be the main focus. If you are not satisfied with the shape, you may need orthopedic treatment, such as cutting the clavicle bone graft to restore the length of the clavicle and achieve a beautiful appearance. Generally, this treatment is not necessary, because it is more traumatic, the recovery time is longer and the effect is not clear. Therefore, without symptoms, it is still recommended to continue observation, which will have no effect on the human body.
