- See: inferior gluteal artery
- major blood supply to gluteus medius and minimus;
- superior gluteal artery and nerve leave the pelvis above piriformis;
- emerges above piriformis, after passing thru greater sciatic foramen;
- once pass the notch, it divides into:
- superficial branch supplying maximus;
- deep branch
- enters deep surface of medius in intermuscular plane between medius, gluteus minimus, & tensor fasciae lata;
- this attachment tethers muscle limiting amount of upward retraction of muscle and prevents one from reaching the iliac crest;
- arterial branches reach as far as the anterior superior iliac spine.
- terminal branches anastomose w/ ascending branch of LFCA ;
- superior gluteal artery appears to be vulnerable to a shearing force because of acute angulation of vessel as it passes out of pelvis;
- superior gluteal artery may be severed by sharp fascia of piriformis, even w/ a minimally displaced frx;
- superior gluteal artery is at risk during operative procedures on greater sciatic foramen
