Sural nerve is one of sensory nerves in lower limb which there are many variations based on origin, branches and path. Information of depth of in the sural nerve is important specially in harvesting. The study was consisting of 40 lower limb specimens in 20 cadavers that sural nerve was evaluated about origin, depth, its relation with lesser saphenous vein and length. Anatomical data was extracted and its origin was classified based on Ramakrishnan’s study. In this study, for the first time, the evidence about the depth of the sural nerve was obtained. In the most cases, nerve pathway passes between fibers of gastrocnemius muscles.
The mean nerve length was reported 36.05 cm and the most common pattern of the origin nerve was type 3A (30%) and type 5 was not observed and no was observed in cadavers in this study. Making of enough information about depth and path of the sural nerve can reduce the iatrogenic injury to the nerve during operative procedures of lower limb.
