The upper side of the clavicle can be felt on one side of the bone and not on the other side of the bone may be caused by congenital deformity, shoulder dislocation, scoliosis. 1. Congenital deformity: if the fetus is injured on one side of the clavicle during delivery or the patient has congenital scoliosis, it may lead to asymmetry of the clavicle on both sides of the patient, so the patient will have a clavicle that can’t be touched by one side of the bone and can’t be touched by the other side of the bone. 2. Shoulder dislocation: patients with shoulder dislocation will have shoulder deformity, shoulder movement disorder, and the affected shoulder is lower than the healthy shoulder, so the patients will have the symptom of not being able to feel the bone on one side of the clavicle. 3. Scoliosis: The cause of scoliosis is still unclear, and it is considered to be related to genetic, trauma, abnormal bone development and other factors. Patients will have asymmetrical thorax, unequal shoulders and so on, which will be manifested as the bone on the upper side of the clavicle can be felt on one side and cannot be felt on the other side. It is recommended that patients need to consult a doctor in time, and the doctor will choose the appropriate measures for the cause of the disease.
