There are many reasons for the slow healing of tibiofibular fractures, the more common ones clinically are the following: First, the fracture of the middle and lower 1/3 of the tibiofibula, which is slow to heal compared to other parts, is determined by its own anatomical structure because there is only one layer of skin in the area, the surrounding muscles and soft tissues are not well developed, and the blood circulation is relatively weak. Second, when the fracture occurs is a comminuted fracture, the healing time is slower compared to ordinary fractures. Third, when the fracture has a very serious open injury with severe soft tissue damage and even infection, the healing time is even slower. However, as long as there is a sign of healing and each film review shows some improvement compared to the last fracture, the fracture can continue to be observed. Usually, if the fracture still does not heal in about 9-12 months, a second surgery is considered to take the iliac bone graft to promote the healing of the fracture.
