Abstract :

INRODUCTION: It has been stated that chronic pain in the distribution of Obturator nerve is a difficult diagnostic challenge.This pain may be explained by the the many potential causes and numerous anatomical structures in the groin area that may be susceptible to injury or disease. These pathologies include adductor muscle strain, stress fractures and entrapment of peripheral nerves.5–12. AIM AND OBJECTIVES: This study was conducted to provide a thorough description of variability in the obturator nerve anching pattern in inguinal region. MATERIAL AND METHODS: The study was conducted on 22(18 male, 4 female), formalin fixed human cadavers available in department of Anatomy, Osmania Medical College, Koti, Hyderabad. RESULTS : Most commonly the anterior anch divided into three major muscular anches that innervated Adductor longus, Adductor evis and Gracilis. The posterior anch predominantly separated into two anches that innervated Adductor evis and Adductor part of Adductor magnus (96.2%). In one case the posterior division of Obturator nerve was supplying Gracilis muscle(4.8%). The point of division of Obturator nerve into anterior and posterior anches was in the thigh (80.24%), Intrapelvic (20.6%). The articular anch of obturator nerve showed different anching patterns, which frequently arose from common obturator nerve. CONCLUSION: High anatomical variability in Obturator nerve’s divisons and subdivisons does exist, and explains the difficulty frequently encountered in application of regional anesthetic techniques.
