Background: In diabetic foot, in case of lacerated wound in lower leg or in case of non healing ulcers in distal part of lower extremity it is very difficult to fill the wound gap. It is because of the area around malleolus and foot, the skin is very tight. Moreover, in between the bones and the skin mainly we are getting muscle tendons without any proper fleshy muscle bulk. so muscular flaps are less available to cover the wound. So based on fascio cutaneous or cutaneous flap generally the repairs were done in the region of lower third of leg. Perforator branches from Posterior tibial artery are the preferred solution in these cases to construct a proper flap. so we have tried to find out details of the perforator arteries based on posterior tibial artery in a cadaveric study. Materials and method: In a dissection based study we have dissected both of the lower limbs of total 10 cadavers. So total samples were 20 posterior tibial artery and their perforators in lower third of leg. Among them 8 were male and 2 were female. All of them were adult cadavers which were properly embalmed. It is a cross sectional study, where we had dissected a cadaver once and collected all of the data once. Result: Out of 20 samples from 10 cadavers, we got among 16 samples, 80% of the fascio cutaneous perforators were Bilateral symmetrical regarding their number and position. Most of the perforators are present within 7-10 cm distance from medial malleolus. Number of perforators in each leg were 3-5. Conclusion: posterior tibial artery perforator based flaps are of high Success rate if we exclude the risk factors. So with proper knowledge of perforators from PTA would help the surgoens to properly care the wounds around ankle and foot. There is probability of racial variation on which more extensive researches are needed.
