Dislocated elbow. Coloured X-ray of the bones (red) in a dislocated elbow joint. The humerus (upper arm bone, upper frame) has moved out of its correct position. It is normally in contact with the ends of the lower arm bones, the ulna (lower frame, left) and the radius. A dislocation is usually accompanied by tearing of the ligaments that hold the bones in place, which causes severe pain. A dislocation restricts or prevents the movement of the joint and causes swelling. If no fractures are present, the joint should be manipulated back into place and immobilized to allow the ligaments to heal.
