Fractures of the lower leg fibula need to be treated according to the specific degree of fracture. First, if the lower end fracture is combined with lower tibiofibular separation, surgical treatment must be performed, through surgical incision and repositioning, steel plate and nail for internal fixation, about 4-6 weeks to review the fracture end healing, according to the degree of healing appropriate removal of external fixation, and then functional exercise of the ankle joint and calf parts; second, if it occurs in the upper leg position, it is easy to cause damage to the common peroneal nerve, if If there is injury to the common peroneal nerve, resulting in numbness and impaired movement of the lower limb, surgical repositioning should be performed to relieve the compression of the nerve and related internal fixation treatment; thirdly, if it occurs in the middle part of the fibula, usually only manual repositioning and external fixation in plaster is needed, because the weight of the fibula in the lower leg is less, even if it does not reach complete anatomical repositioning, it does not affect the functional activities.
