Abstract

The study was aimed to investigatethe anatomical landmarks for regional anesthesia in hind limb of7adultBlack Bengal goatof either sex at Anatomy lab, CVASU.4 male and 3 female Black Bengal goats aged between 2-3 years and weighting 8.2±0.51kg wereused for this study.With thepermission of ethical committee of CVASU, the animals were euthanized and then used for dissectionto expose the nervesof hind limbs. Ischiatic nerve was alwayspresent under the biceps-femoris muscles and 1.24±0.11 cmcaudo-medial from the greater trochanter of femur. Fibular nerve was found superficial along the lateral aspect of the gastrocnemius muscle which wasalso1.1±0.04cmaway from thestarting point of tibial crest in its lateral aspect. Tibial nerve was passed between the two head of gastrocnemius muscle and later became superficial in front of Achilles tendon.To block the tibial nerve, more appropriate site was found at3.05±0.12 cmabove from calcaneus bone.This study established reference anatomical landmarks for regional anesthesia (blocking of ischiatic, fibular and tibial nerve) in hind limb of Black Bengal goat.
