The greater sciatic notch is a notch in the ilium, one of the bones that make up the human pelvis. It 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.

The notch holds the piriformis, the superior gluteal vein and artery, and the superior gluteal nerve; the inferior gluteal vein and artery and the inferior gluteal nerve; the sciatic and posterior femoral cutaneous nerves; the internal pudendal artery and veins, and the nerves to the internal obturator and quadratus femoris muscles.

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

The greater sciatic notch is wider in women (about 74.4 degrees on average) than in men (about 50.4 degrees).[1]

Which bone is the greater sciatic notch located?

The greater sciatic notch is a notch in the ilium, one of the bones that make up the human pelvis. It lies between the posterior inferior iliac spine (above), and the ischial spine (below).

Where is the greater and lesser sciatic notch?

The lesser sciatic notch lies below the ischial spine, and is converted into the lesser sciatic foramen by the sacrospinous and sacrotuberous ligaments. The greater sciatic notch lies between the ischial spine (inferiorly) and the posterior inferior iliac spine (superiorly).

What makes the greater sciatic notch?

The greater sciatic foramen is an opening (foramen) in the posterior human pelvis. It is formed by the sacrotuberous and sacrospinous ligaments. The piriformis muscle passes through the foramen and occupies most of its volume.

Who has a wider sciatic notch?

People who die at a younger age tend to have wider, more feminine-appearing sciatic notches than people of greater longevity. There are also significant population differences. The 18th-19th century English sample from St.
