How do you know if a bone is broken?

After the bone is broken, it can be judged by the following signs. First, local obvious pain and swelling, as well as obvious tenderness. Second, there will be a bone rubbing feeling in the broken part of the bone, and there will be bone rubbing sounds when moving. Third, there will be local deformity, even abnormal movement, and instability of the fracture end will be felt. Fourth, the most intuitive words are through X-ray, X-ray will indicate the fracture site of the trabecular bone interruption and fracture end angulation, shortening, or rotation of the shift. If X-ray can not be diagnosed, sometimes it may be further confirmed by CT or MRI.
