ABSTRACT
High division of the sciatic nerve was found bilaterally in a 70 year old male cadaver. Common peroneal nervewas found piercing the piriformis muscle dividing the muscle into upper and lower slips. Tibial nerve was foundemerging below the lower slip of the piriformis muscle. Inferior gluteal nerve was formed by two roots oneabove and one below the lower slip of the piriformis muscle. Here in this case report we discuss the possiblesciatic nerve entrapment due to this kind of variations and we also discuss the two conditions named sciaticaand the piriformis syndrome.
