- See Superior Gluteal Artery:
- inferior gluteal artery leaves pelvis below piriformis and above superior gemelli (after passing greater sciatic foramen );
- main trunk of artery is vulnerable as it emerges from beneath lower border of pirformis when pelvic fractures involve greater sciatic notch;
- it spreads superiorly and sends branches to maximus and muscles arising from the ischial tuberosity & may reach as far as lower part of the thigh;
- small branches pass medially as far as the skin over the coccyx.
- inferior gluteal branches are cut when gluteus maximus is splt;
- anastomotic branch descends across short lateral rotator muscles of hip & contributes to cruciate anastomosis of back of thigh.
- cutaneous branches accompany radicles of posterior femoral cutaneous nerve & an accompanying artery of sciatic nerve .
