A large bag at the end of the fracture that does not go away will affect the repair and healing of the wound, and if the healing is deformed, it will also affect the normal movement of the joint. There is a big bag at the end of the fracture because the bleeding of the fracture end will form obvious subcutaneous hematoma at the fracture site, hematoma will affect the local blood circulation and nutrient supply, which will affect the repair and healing of trauma, and in serious cases, it will also cause ischemia of the limb, resulting in local necrosis and other conditions. The lack of strict bed rest after fracture will lead to displacement of the fracture. In addition, if the fracture is internally fixed, the lack of bed rest or unstable internal fixation may also lead to malunion, which will also lead to a large bag at the end of the fracture, and malunion may affect the normal activities of the joint. If the fracture does not go away, it is recommended to go to the hospital for treatment.
