Journal Title:International Journal of Ayurveda and Pharmaceutical Chemistry
Abstract


Sciatic nerve is the thickest nerve in the body. Sciatic is Greek word derived from “Ischiadicus”. The sciatic nerve is also known as the ischiadic nerve or ischiatic nerve. In its upper part, it forms a band about 2 cm wide. It is the largest branch of the sacral plexus. It is formed on the right and left hand side of the lower spine. It is derived from the spinal nerves L4-S3. It contains fibres from both the anterior and posterior divisions of the lumbosacral plexus. It begins in the pelvis and terminates at the superior angle of the popliteal fossa by dividing into the tibial and common peroneal (fibular) nerve but the bifurcation may vary. Occasionally the nerve separates as they leave the pelvis. The present case is a report of an unusual bifurcation of sciatic nerve in the gluteal region. The knowledge of the variation in the level of bifurcation of the sciatic nerve should be kept in consideration while performing surgical exploration of that region.
