The vast majority of fibula fractures in children recover well. However, due to the special nature of fibula fracture, it is prone to delayed healing or non-union of the fracture due to its low blood supply, and in severe cases, osteofascial compartment syndrome may occur. The lower leg consists of the tibia and fibula, and the fibula only accounts for 1/6 of the weight-bearing. If the fracture is well aligned and externally immobilized with a plaster cast, most of the fractures are able to heal completely after treatment. If the fracture line is located at the distal end of the fibula, that is, the middle and lower 1/3 of the fibula, the fracture is prone to non-union due to its low blood supply. X-rays can be taken periodically to check the healing status of the fracture, and surgery can be performed if necessary. If a child suffers a fracture of the fibula as a result of an accidental trauma, it is recommended that the child go to the hospital in time for medical examination. Improve the examination and receive regular treatment.
