A clavicle that is not the same height may be due to a physiologic abnormality, or it may be due to a pathology such as scoliosis or acromioclavicular joint subluxation. It can be corrected through exercise and surgery. 1. Physiological abnormality of different heights of clavicle: it is usually caused by different pressure on the left and right side for a long time in daily life. If there is no obvious clinical symptom, it is physiological abnormality. Patients can go to the hospital for chest radiography, massage, physiotherapy and other ways to improve this situation. 2. Scoliosis: Bilateral clavicle height difference is also seen in scoliosis, i.e., bilateral clavicles are not on a horizontal line when bending sideways. In this case, you should consult a doctor in time, with physical examination and take spinal films. Scoliosis less than 30 degrees can be treated conservatively with orthopedics and massage. Larger scoliosis requires surgery. 3. Dislocation of acromioclavicular joint: it is often caused by trauma and should be treated promptly. If there is clavicle fracture, orthopedic doctor should check whether there is pain or bone friction when pressing the clavicle, and improve the clavicle X-ray. It can be fixed and corrected by resetting and bandage external fixation. In addition, inflammation, bone tumor, congenital clavicle deformity and other causes can lead to clavicle deformation. It is recommended that patients whose clavicles are not the same height should actively seek medical treatment and take appropriate treatment and corrective measures according to the doctor’s instructions after the cause is identified.
