The methods to determine whether there is a bone fracture are local symptoms and X-ray examination, as follows: 1. Local symptoms: When a patient has a traumatic injury, the local limb swells very quickly, and a fracture should be suspected. 2. X-ray examination: Whether a patient has a fracture, such as a bone fracture, is difficult to determine by surface observation, because when a soft tissue injury, muscle injury or a bone fracture occurs, the soft tissue, local limb There will be obvious swelling, so X-rays must be taken, and if the film shows that a bone fracture has occurred, it will be clear that it is a bone fracture. If no obvious fracture line is seen on the X-ray, generally, fracture can be ruled out, so when trauma is accompanied by swelling of the limb, an X-ray must be taken early.
