A study on the applied anatomy and complication of fibula transplantation with vascular

Objective To provide anatomical data to explain the clinical complications produced after vasculatized fibula grafts and put forth some suggestions to avoid those complications.Methods The whole length of fibula was divided into three portions.The nutrient artery,the nourish artery of the fibular periosteum around the fibular were dissected to measure and observe on the lower extremities of 8 cases(male 6 and female 2) which are preserved integrity.Results On superior segment of the fibular,one branch from the popliteal artery moving towards the capitulum branched out three arteries.One of them run downwards(diameter of 0.161 cm) and turned to nourish artery of the fibular periosteum.The second branch hooked the fibula horizontally and run backwards.The third(diameter of 0.155 cm) went upwards with the length of 1.75 cm averagely,then entered the knee joint directly.In the middle segment,tiny nutrient arteries of fibula entered the fibula regularly besides the main nutrient artery(diameter of 0.210 cm) of fibula.Generally,there is an artery to fibular periosteum(diameter of 0.195 cm) came from the fibular artery.In the lower segment,there are 2-3 arcuate arteries originated from the fibula artery(diameter of 0.075 cm) to supply the muscles located lateral to the fibula.Conclusion Taking place of complications after the vacularized fibula graft had close relationship with the distribution of arteries around fibula,Protection of the those arteries will contribute great deal to the reduction of complications occurrence.
