Anastomotic fibular resection

The fibula has an independent blood supply system (fibula arteries and veins), which does not affect the blood supply of the lower limbs after being cut off, and the fibula arteries and veins can be separated into long pedicles. The average outer diameter of the artery is 2.0-2.5mm, and the outer diameter of the accompanying vein is 2.0-3.0mm, which is convenient for vascular anastomosis. The length of an adult fibula is 28-30cm. Except that the lower end 5-6cm is necessary to stabilize the ankle joint, the rest can be used for transplantation. In addition, the fibula is straight, without curvature or curvature. Therefore, the fibula is most suitable for repairing large bone defects in the long bones of the extremities.
