Whether a tibiofibular fracture can recover after 90 days of conservative treatment needs to be judged according to the severity of the fracture, which is usually able to heal basically in 3 to 6 months and completely in 1 to 2 years. If the fracture damage is mild, it is possible to heal basically after 90 days; if the fracture is more serious, it cannot heal after 90 days. 1. Tibiofibular fracture mostly occurs under the effect of strong violence such as fall from height, car accident and trauma, etc. The fracture is more complicated, conservative treatment mostly adopts manipulation reset, plaster external fixation and other treatments, usually it can be basically healed in 3-6 months, and can be completely healed in 1~2 years. 2. If there is no obvious comminuted fracture of the tibia and fibula, the fracture is in good alignment after repositioning, and the blood circulation around the fracture is good, the fracture is likely to heal after 90 days of conservative treatment. 3. If the tibial fibula is a more serious comminuted fracture, the fracture combined with the surrounding blood vessel damage, poor blood circulation, conservative treatment 90 days after the fracture is more difficult to achieve basic healing. The specific recovery after conservative treatment of tibiofibular fracture, it is recommended to consult the doctor in a timely manner, improve the relevant examination, under the guidance of the doctor.
