The body of the ischium enters into and constitutes a little more than two-fifths of the acetabulum.


Its "external surface" forms part of the lunate surface of the acetabulum and a portion of the acetabular fossa.

Its "internal surface" is part of the wall of the lesser pelvis; it gives origin to some fibers of the Obturator internus.


Its "anterior border" projects as the posterior obturator tubercle.

From its "posterior border" there extends backward a thin and pointed triangular eminence, the ischial spine, more or less elongated in different subjects.

Above and below the spine

"Above" the spine is a large notch, the greater sciatic notch.

"Below" the spine is a smaller notch, the lesser sciatic notch.
