When the phenomenon of pain after ten days of fracture occurs, the following causes are mainly considered: 1. After the fracture is usually braked with a cast or brace, the affected limb must be elevated during the braking period. If the affected limb is often in a sagging state for ten days, it may make it difficult for blood to return to the fracture site, which can cause persistent swelling and persistent swelling of the limb. 2. It is possible that the plaster fixation fails, such as when the plaster fixation is carried out, the plaster and bandage are not firmly wrapped around the fracture site, or the plaster fixation gradually loosens during activities at home and loses its solid fixation, which can cause micromovement of the fracture break and may lead to pain. It may lead to pain. 3. It is possible that during the plaster fixation the patient goes down to the ground to bear weight and walk too early, which can make the external fixation fail and also cause fracture pain.
