Background:  The sciatic nerve ,the principal nerve of the posterior compartment of the lower limb normally divides at the superior angle of popliteal fossa.Sometimes there could be higher division,the knowledge of which is important in avoiding inadvertent injury during surgeries in the gluteal region .
Materials and Method: The study was conducted in 64 lower limbs at Government Stanley Medical College,Chennai and Government Mohan Kumaramangalam Medical College,Salem.
Results: In 60 limbs, the sciatic nerve divided at superior angle of popliteal fossa.In 3 limbs,there was higher division at the level of upper part of the thigh.In 1 limb,there was intrapelvic division of nerve with split piriformis.
Conclusion: Knowledge of these variations help during popliteal nerve blocks and in the management of nondiscogenic causes of sciatica.
KEY WORDS: Tibial Nerve, Common Peroneal Nerve, Sciatica, Piriformis syndrome, Popliteal  block.
