Cadaveric study of the exit of sciatic nerve pattern: observational study
Journal Title: Applied Physiology and Anatomy Digest - Year 2018, Vol 3, Issue 2
Abstract
Introduction: The sciatic nerve is also known as the ischiadic nerve or ischiatic nerve, is a large nerve in humans and other animals. It is the longest and widest single nerve in the human body. The sciatic nerve is comprised of five nerves. Material and methods: The present study was carried out in department of Anatomy for one year duration. 30 gluteal regions were examined in 15 formalin fixed cadavers with no pathology during the period of one years. Fifteen of the cadavers were male and fifteen were female. The sample size was estimated with the help of expert. Results: Variations in SN bifurcation were seen in 2 cadavers . Totally six lower limbs showed variation in the division of sciatic nerve Male cadaver on the left lower limb showed that sciatic nerve divided in the pelvis, CPN nerve emerged through the bifid piriformis and TN below the muscle . Male cadaver showed bilateral variation. Sciatic nerve on the right side divided about 50 mm above the popliteal crease (0-150 mm) but below the superior angle of popliteal fossa. On the left side Sciatic nerve divided at the level of the popliteal crease . Conclusion: The sciatic nerve is frequently involved in daily medical practice of neurology, orthopedics, rehabilitation and anesthesia. Sciatic neuropathy is the result of injuries, leading to neurological defects. Its long course makes it vulnerable to nerve injury.
