Clavicle side high and low need to be determined by the specific circumstances, can not be generalized, there are pathological changes, there is a normal physiological state, divided into different cases, as follows: 1, child development: if the clavicle side high and low, may be the development process of the phenomenon, the late development of maturity after the two sides can basically restore a more symmetrical state. But if there is a lesion problem, pay special attention, such as rickets or calcium deficiency disease, or the bone itself, such as tumors or other problems may appear clavicle is not symptomatic, then be sure to review the X-ray, or blood sampling to understand the electrolytes or trace elements have no abnormalities, if there is abnormal, timely supplementation. If the clavicle is high on one side and low on the other caused by a lesion tissue, it needs attention, such as giant cell tumor of bone or other tumors can also lead to this situation, the X-ray can be further clarified; 2, adults: if the clavicle is high on one side and low on the other side in adults most of the time there is no obvious problem, need to pay attention to whether there are symptoms, there is no pain, there is no local redness, swelling, percussion pain, depending on the situation. If there are no symptoms, most people are the normal reaction left after development, is a normal physiological phenomenon, and do not need to pay special attention. If the symptoms are more obvious, it may be caused by local soft tissue swelling, or it may be caused by the bone itself, such as bone tumor or soft tissue tumor, or it may be a tumor of the thorax, which may cause the clavicle to be high on one side and low on the other. However, in general, most of the clavicle is high and low at one side is normal. If there are no obvious symptoms and the clavicle is not painful, red or swollen, it is generally not necessary to pay special attention to it. If it lasts longer and the symptoms are more obvious, this is the time to improve the relevant tests to further clarify the diagnosis.
