The Vascular Supply of Hip Joint and its Clinical Significant

Abstract

AL-TALALAH, WW . The vascular supply of hip joint and its clinical significant. Int. J. Morphol., 33(1):62-67, 2015.SUMMARY: The hip joint gains its vascular supply from the superior gluteal arteries as well as from the medial and lateralcircumflex femoral arteries with the first perforating artery. In gluteal trauma, the superior and inferior gluteal artery may be affectedwhich may end with vascular insult of hip joint. The current study includes a dissection of 171 cadavers to examine the vascula r supplyof hip joint. In 99.3% of articular branch arises from the superior gluteal artery either directly or indirectly (95.4% or in 3 .9%, respectively).In 81% of articular branch arises from the inferior gluteal artery either directly or indirectly in 78% or in 3%. In 20.3% of a rticular brancharises from the coexistence of sciatic artery either directly or indirectly (17.7% or in 2.6%, respectively). Infrequently, the internalpudendal artery gives articular branch in 0.4%. Further, there is no difference between male and female in hip joint supply in currentstudy. Based on current study’s result, the dominant articular branch of vascular supply of the hip joint comes from the superi or glutealartery whereas the inferior gluteal artery comes beyond due its congenital absence. The coexistence sciatic artery is a replace ment arteryfor superior or inferior gluteal artery in case of congenital absence. Due to aneurysm of the three previous arteries after trauma, it isimportant to study their course and articular branches to avoid iatrogenic fault of joint vascular insult during surgical management ofeither true or false aneurysm.KEY WORDS: Superior gluteal artery; Gluteal artery; Sciatic artery; Hip; Inferior gluteal artery; Persistent axial artery;Gluteal trauma; Iatrogenic fault of joint; Gluteal aneurysm, Rami comes nervi ischiadici; Articular branch.
