The fascia of the Obturator internus (or Obturator fascia) covers the pelvic surface of, and is attached around the margin of the origin of, the muscle.
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
Obturator internus, it gradually separates from the iliac fascia and the continuity between the two is retained only through the periosteum.
Below, the obturator fascia is attached to the
falciform processof the sacrotuberous ligamentand to the pubic arch, where it becomes continuous with the superior fascia of the urogenital diaphragm.
Behind, it is prolonged into the
The internal pudendal vessels and pudendal nerve cross the pelvic surface of the Obturator internus and are enclosed in a special canal—
Alcock’s canal—formed by the obturator fascia.
