Simple fibula fracture with good alignment and alignment has the possibility of self-healing. However, if the fracture is comminuted or displaced, accompanied by neurovascular, it is difficult to heal without treatment, and it is best to perform surgery when the injury occurs. If the fracture is simple fibula fracture, there is no obvious displacement after fracture, good alignment, if the affected limb is not moved, there is also a possibility of self-healing. Some simple fibula fractures may go untreated because the symptoms are not serious at the time, and it is only after the fracture has healed that it is realized that there was once a fracture of the fibula. However, the risk of untreated fractures is high, leading to malunion or swelling that does not resolve, so active treatment is recommended. Good alignment is generally feasible for 4-6 weeks of cast or brace immobilization, and functional exercise after removal of the cast. If the fibula fracture is severely comminuted, or the displacement of the fibula fracture close to the ankle joint is large, or accompanied by vascular or nerve injury, it cannot be healed by itself, and needs to be operated in time, and the treatment of incision and reduction and internal fixation. Fibula fracture is treated differently depending on the physical condition and the severity of the disease, and should be treated in time.
