Above, it is loosely connected to the back part of the arcuate line, and here it is continuous with the iliac fascia.

In front of this, as it follows the line of origin of the internal obturator, it gradually separates from the iliac fascia and the continuity between the two is retained only through the periosteum.

It arches beneath the obturator vessels and nerve, completing the obturator canal, and at the front of the pelvis is attached to the back of the superior ramus of the pubis.

The internal pudendal vessels and pudendal nerve cross the pelvic surface of the internal obturator and are enclosed in a special canal—Alcock's canal—formed by the obturator fascia.
