TOPOGRAPHIC VARIATIONS OF SCIATIC NERVE IN RELATION TO PIRIFORMIS
Journal Title: Journal of Evidence Based Medicine and Healthcare - Year 2018, Vol 5, Issue 50
Abstract
BACKGROUND The aim of this study was to evaluate the anatomical relationship between piriformis muscle and sciatic nerve. Sciatic nerve is thickest nerve commonly dividing into tibial nerve and common fibular nerve. It is derived from lumbosacral plexus L4 to S3 spinal nerves. Aim of the present study is to find out the relations of sciatic nerve and its relation to piriformis muscle. MATERIALS AND METHODS 60 gluteal regions and posterior compartment of thigh were studied from 30 formalin fixed cadavers kept for dissection, out of which 27 were male cadavers and 3 were female cadavers. RESULTS Normal course of sciatic nerve was studied in 50 limbs, out of which 10 limbs had variations in division in relation to piriformis muscle. CONCLUSION Knowledge of variations of sciatic nerve in relation to piriformis is useful in anaesthetic procedures, hip arthrodesis and treating sciatic nerve compression.
