The main treatment methods for children with complete fracture of the calf bone include external fixation with a brace or plaster cast and internal fixation with surgical incision, etc., which should be chosen according to the patient’s condition, and there is no so-called “optimal” treatment method. If the child’s calf bone is completely fractured but not dislocated, conservative treatment can be chosen, i.e. external fixation with support or plaster cast, and strict braking is required. X-rays will be taken about 1 month later to review the healing of the fracture. If the fracture of the calf bone is severely dislocated on both sides of the fracture, even with blood vessels and nerves embedded in the case, then it is necessary to surgically cut and replace the internal fixation treatment, about 1 month after taking X-ray to review the healing of the fracture. The specific treatment plan should be chosen according to the patient’s condition assessment and basic physical condition, please follow the doctor’s advice.
