The Sciatic Nerve after originating from sacral plexus leaves the pelvis through the lower part of greater sciatic foramen into the gluteal region and divides into two components at any level from its origin to its usual division inside the upper part of popliteal fossa. It was observed that the left sided sciatic nerve divided into its two components inside the pelvis. The tibial and common peroneal nerves after leaving through greater sciatic foramen sandwiched piriformis muscle in the gluteal region. The common peroneal nerve passed above the piriformis where as the tibial nerve passed inferior to this muscle. . The higher division of sciatic nerve inside the pelvis though rare is of great academic and clinical significance in Neurology, General Surgery, Orthopaedics, Anaesthesiology, Sports medicine and physiotherapy. The knowledge of this variation is also important for paramedics who frequently give intramuscular injections into the gluteal region
Maybe, in this case, the nerve can be susceptible to piriformis syndrome
