Background: Being the body's widest nerve the sciatic nerve gives two major Tibial and Common Peroneal components branches that form the nerve supply of the gluteal and posterior thigh region. They come from the ventral rami of the lumbosacral plexus' L4 to S3 spinal nerves. Underneath the Piriformis muscle, it leaves the pelvis through the greater sciatic foramen and travels to the knee in the back of the leg. This research aims to recognize the variations in the sciatic nerve's branching structure. Methods: Sixty lower limb specimens from Thirty formalin-fixed cadavers (26 male and 4 female) were used in the investigation (52 Male & 8 Female). To reveal the sciatic nerve, the gluteal area and posterior compartment of the thigh were dissected. We observed and documented variations in the piriformis muscle's proximity to the sciatic nerve bifurcation. Results: Of Sixty lower limb specimens, Fifty-five (92%) displayed normal sciatic nerve architecture, whereas the remaining 5 (8%) displayed abnormalities. Result: In our study, 92% of the specimens (55 specimens) were classified as type I, 5% (3 specimens) as type II, and 3% (2 specimens) as type III. Beaton and Anson's classification type IV, type V, and typeVI specimens are not present in our study. Conclusion: The SN's bifurcation does not vary during regular dissections, but occasionally we may detect dividedor undivided SN components, which should be taken into consideration when treating patients for sciatica, hip operations, and gluteal injection SN block. These variations in bifurcations should be noted by experts before continuing with the surgical treatment plan.
