ON THE SUPERIOR AND INFERIOR GLUTEAL VESSELS AND NERVES (Abstract): Superior and inferior gluteal vessels and nerves consist of: superior gluteal nerve, inferior gluteal nerve, superior gluteal artery, inferior gluteal artery. Superior gluteal nerve travels through the greater sciatic foramen, superior to the piriformis muscle, and then laterally, between the gluteus medius and the gluteus minimus muscles. Inferior gluteal nerve outgoes from the posterior branches of L5 through S2 and has a trajectory through the greater sciatic foramen, inferior to the piriformis muscle. The superior gluteal artery is the largest branch of the internal iliac artery, being the continuation of the posterior division of that vessel. Inferior gluteal artery may form a common trunk with the superior gluteal artery. Our study was carried out on 12 dissected adult specimens, males and females. We followed each element and drawn conclusions, comparing them with the literature data. Our findings showed in less cases (60%) than in literature (75%) the inferior gluteal artery arising from the anterior division of the internal iliac artery , and no double artery.
Key words: SUPERIOR GLUTEAL NERVE, GREATER SCIATIC FORAMEN, INFERIOR GLUTEAL ARTERY
