The common causes of clavicle asymmetry include bad habits, developmental deformities, trauma, etc. The cause of clavicle asymmetry should be clarified and appropriate correction program should be chosen. It is necessary to choose appropriate corrective programs after clarifying the causes, such as correcting bad posture, bar training methods, surgical treatment and so on. 1. Bad life habits: such as incorrect sitting or sleeping posture, often head tilted to one side, etc., which can make the clavicle asymmetrical to one side for a long time. It can be corrected by correcting bad habits such as sitting posture, sleeping posture or bar training. 2. Developmental deformity: such as congenital clavicle asymmetry or pseudo clavicular joint, if it does not affect daily life and work, it can not be overly dealt with; if it affects daily life and work, then surgical treatment such as arthrodesis, internal fixation, autologous iliac bone grafting and so on is needed. 3. Trauma: If the clavicle fracture is not well braked and immobilized during the fracture healing process, resulting in the clavicle only reaching functional reset but not anatomical reset, the appearance of bilateral clavicle may be asymmetric during the development in the future. If it does not affect the function, no special treatment is needed; if it has affected the daily life, elective surgery is needed. If you find asymmetry of the clavicle, you should go to the hospital in time and do the relevant examination to clarify the cause of the disease and guide the treatment, do not do it by yourself. Good habits are needed in daily life.
