Variations of the nutrient artery of the fibula

In this study the authors aimed to show variations of the nutrient artery of the fibula, which is important for more effective vascularized fibular grafts. Thirty intact legs were examined to determine the number, location, and diameter of the nutrient arteries in the shaft. In 27 of these specimens (90%) there was single nutrient artery; two legs (6.6%) had double nutrient artery. In one leg (3.3%) no nutrient artery was observed. The number of nutrient arteries found on each of the surfaces was summarized as follows. Most of the nutrient arteries pierced the fibula at its medial crest, while only one entered from the posterior surface. Most nutrient arteries were near the middle third of the fibula. The most frequent diameter of the nutrient artery was 0.9–1.5 mm. The authors think that their results about the variations of the nutrient artery supplying the fibula will contribute to the clinical and vascular anatomy knowledge. Clin.
