Bone rattling when the arm is turned in a circle is most likely due to excessive friction between ligaments and bones. The presence of such a rattle does not mean that the patient has a disease, but is most likely caused by the bones and muscles being in one position for a long time. Patients do not have to worry about it, and can do physical therapy or baking electricity to the elbow or ankle joints appropriately to avoid excessive weight on the joints. At the same time, you can increase sports and exercise to enhance the strength of ligaments and muscles, the friction between bones and ligaments will be reduced a lot, and the ringing will not appear. X-rays also need to be reviewed in a timely manner to avoid the possibility of osteoarthritis.
