Abstract
INTRODUCTION: Soft tissue defect on lower limb can result in an intractable wound. Surgeons resort in flaps to cover these injuries. Including fascia as in the case of a fasciocutaneous flap increases survey of the flap. Rising a perforator flap avoids to sacrifice a major vessel whence the nourishing perforator artery is born. We wanted to explore suprafascial distribution of the fibular skin perforator arteries supposing possible to find out a vascular axis composed of anastomoses of the fibular perforator vessels. MATERIALS AND METHODS: Systematic observation was carried out on ten injected legs about the fibular perforator distribution, and especially their suprafascial course. RESULTS: Dissection allowed us to raise in all specimens a large fasciocutaneous paddle including a fine arteriolar vessel connecting fibular perforators. Perforators were isolated along from the leg and we found suprafascial arteriole connecting all perforators from the fibular head to the lateral malleolus. There were a total number of 126 perforators for 10 legs. The mean length of the fibula was 32.9 cm. No perforator was located at more than 2 cm from fibular posterior border. Proximal perforators were closer to posterior fibular side than distal perforators. We found that fibular perforators clustered in the middle and upper third of the leg. CONCLUSION: This study proves the real existence of a microvascular suprafascial axis formed by fibular perforator anastomoses and stretching over the entire length of the fibula, from the fibular head to the distal tip of the lateral malleolus. This suprafascial vascular axis could be an anatomical basis for a fasciocutaneous fibular flap.
