Simple fibula fracture can be partially weight-bearing activities with crutches 2~4 weeks after surgery, and when combined with other fractures or injuries, crutches should be used for activities 6~8 weeks after surgery. The calf bone consists of tibia and fibula, fibula is not the main weight-bearing bone, about 20-30% of the weight-bearing, fibula fracture such as displacement or fibula fracture of the lower part of the fibula caused by the damage to the articular surface, often need surgical treatment, such as incision and reduction of internal fixation. If there is no injury to the ankle joint in simple internal fixation of fibula fracture, as the fibula is not the main weight-bearing bone, the incision will be healed and the edema will subside in 2-4 weeks after the operation, then the patient can go down to the ground with the help of crutches and partially load-bearing activities, and exercise the muscles and joints of the lower limbs, which is conducive to the recovery of the fracture. If the fibula fracture is accompanied by tibia fracture or ankle joint injury, it is necessary to start walking on the ground with the help of crutches after the bone scabs start to form in 6~8 weeks after the operation. Generally speaking, the fracture is basically healed in 10~12 weeks after the operation, and you can remove the crutches, start weight-bearing exercises, and gradually resume normal walking. Fibula fracture patients must follow the doctor’s treatment and rehabilitation recommendations, under the guidance of the doctor to carry out rehabilitation exercises, to avoid early weight-bearing, so as not to affect the healing of the fracture.
