Greater sciatic notch
Updates to Article Attributes
Body
was changed:
The greater sciatic notch is a large notch in the pelvis above the ischial spine. The addition of the sacrospinous ligament converts the notch into the greater sciatic foramen.
It transmits the piriformis muscle, the superior and inferior gluteal vessels and nerves, the sciatic and posterior femoral cutaneous nerves, the internal pudendal vessels, and nerve, and the nerves to the obturator internus and quadratus femoris.
Of these, the superior gluteal vessels and nerve pass out above the piriformis muscle and the other structures below it.
