Anatomical terms of bone

The greater sciatic notch lies between the posterior inferior iliac spine (above), and the ischial spine (below). The sacrospinous ligament changes this notch into an opening, the greater sciatic foramen.

It transmits the piriformis, the superior and inferior gluteal vessels and nerves, the sciatic and posterior femoral cutaneous nerves, the internal pudendal vessels, and the nerves to the obturator internus and quadratus femoris.

Of these, the superior gluteal vessels and nerve pass out above the piriformis, the other structures below it.
