The area between the ankle and calf is called the middle and lower 1/3 of the tibia. After a fracture of the middle and lower 1/3 of the tibial stem, there is little soft tissue coverage resulting in easy damage to the nourishing arteries and nutrient vessels, and insufficient blood supply to the fracture severed end, which can easily lead to non-union of the fracture, i.e., bone nonunion. Poor local soft tissue conditions, long-term non-healing local soft tissue infection of the fracture, or the formation of a large area of scar tissue will affect the blood supply to the fracture severed end, which is not conducive to fracture healing. It is important to pay enough attention after the fracture of the middle and lower 1/3 of the tibial trunk, and to choose a professional and regular orthopedic department for systematic treatment to reduce the risk of postoperative complications or sequelae.
