STUDY OF VARIATION IN THE HIGH DIVISION OF SCIATIC NERVE AND ITS RELATIONSHIP WITH THE PIRIFORMIS MUSCLE
Keywords:
Sciatic Nerve, Sciatica, Greater Sciatic Foramen, Gluteal Region, Piriformis Syndrome
Abstract
The sciatic nerve which is a branch of sacral plexus divides into its terminal branches i. e. tibial and common peroneal in the posterior compartment of the thigh. But sometimes rarely it divides in pelvis and exit through pelvis by different routes. Because of this variant course, it bears varied relationships with the muscles of the gluteal region. The nerve may be compressed by muscles or vessels. This results in the Sciatica of nondiscogenic variety. So the aim of this study is to define the level of exit and division of the sciatic nerve.
