To know whether the fracture has healed or not, it is necessary to perform a local plain X-ray examination mainly based on the time after the fracture, local clinical symptoms and signs, etc. For example, if the fracture has been actively treated for 3-4 months, there is no local pressure pain or percussion pain, and a local plain X-ray examination reveals that there is a large amount of local bone scab growth, the fracture line has completely disappeared, and the medullary cavity has been penetrated, it means that the fracture has completely healed. To promote rapid healing after the fracture, fracture repositioning, local protection, and functional exercise are needed as follows: 1. Fracture repositioning: first of all, the displaced fracture needs to be repositioned, and the repositioning process should reduce the damage to local soft tissues and periosteum, otherwise it will affect the patient’s fracture healing. 2. Local protection: after the repositioning, strict local protection and braking are needed, which is the best condition for the patient’s fracture healing. 3. 3. Functional exercise: When the local bone scab has grown and is relatively stable, it is necessary to diligently perform functional exercise.
