		The ridges are continuous with similar ones on the inferior ramus of the pubis: to the outer is attached the deep layer of the superficial perineal fascia (fascia of Colles), and to the inner the inferior fascia of the urogenital diaphragm.
		The inferior surface forms the upper boundary of the obturator foramen, and presents, laterally, a broad and deep, oblique groove, for the passage of the obturator vessels and nerve; and medially, a sharp margin, the obturator crest, forming part of the circumference of the obturator foramen, and giving attachment to the obturator membrane.
		The ridges extend downward, and are continuous with similar ridges on the inferior ramus of the ischium; to the external is attached the fascia of Colles, and to the internal the inferior fascia of the urogenital diaphragm.

		Deep to the external oblique muscle is the internal oblique muscle with obliquely and superiorly oriented fascicles arising from the iliac fascia deep to the lateral half of the inguinal ligament, from the anterior two thirds of the iliac crest, and from the lumbodorsal fascia.
		The obturator internus muscle arises from the margins of the obturator foramen and the obturator membrane.
		The muscle fascicles exit the pelvis at the lesser sciatic foramen and have a tendinous insertion on the medial surface of the greater trochanter of the femur.

		In the upper part of its course the nerve rests upon the posterior surface of the ischium, the nerve to the Quadratus femoris, the Obturator internus and Gemelli, and the Quadratus femoris; it is accompanied by the posterior femoral cutaneous nerve and the inferior gluteal artery, and is covered by the Glutæus maximus.
		It is placed on the deep muscles, and lies at first to the medial side of the posterior tibial artery, but soon crosses that vessel and descends on its lateral side as far as the ankle.
		The perforating cutaneous nerve may arise from the pudendal or it may be absent; in the latter case its place may be taken by a branch from the posterior femoral cutaneous nerve or by a branch from the third and fourth, or fourth and fifth, sacral nerves.

		The feasibility of using obturator internus muscle autotransplantation in order to construct an anal dilator mechanism for the treatment of obstructive constipation was studied anatomically, physiologically and pathologically.
		Electromyographic studies of 15 obturator internus muscles in 10 healthy adult male volunteers and 3 other muscles in patients with documented spastic anal sphincters demonstrated the ability of the obturator internus muscles to contract during straining at stools.
		The proposed surgical approach was studied in 9 cadavers (5 stillbirths and 4 adults), followed by formal anatomical dissection of the obturator internus muscle and tendon, pudendal nerve and vessels, inferior rectal nerve and nerve to the obturator internus.

		With the development and contraction of the muscles of the pelvis, the trochanteric fossa is formed to allow for the insertion of the obturator internus, the obturator externus, and the gemelli muscles.
		The apophysis for the attachment of the iliopsoas muscle on the lesser trochanter of the femur is abnormally large and roughened.
		The Voss procedure involved release of the gluteal muscles by trochanteric osteotomy, tenotomy of the proximal insertion of the adductor muscles, and myotomy of the tensor fasciae latae.

		It arises from the inner surface of the obturator membrane lining the obturator foramen and the neighbouring surfaces of the pubis and ischium.
		It is innervated by the nerve to obturator internus (L5, S1), a branch of the sciatic nerve.

		The surface marking of the superior border of the piriformis muscle is indicated by a line joining the skin dimple formed by the posterior superior iliac spine, to the superior border of the greater trochanter of the femur.
		The obturator internus and gemelli muscles laterally rotate the extended thigh, abduct it when it is flexed and also help to hold the head of the femur in the acetabulum.

		}} The obturator internus muscle originates on the medial surface of the obturator membrane, the ischium near the membrane, and the rim of the pubis.
		It also arises from the pelvic surface of the obturator membrane except in the posterior part, from the tendinous arch which completes the canal for the passage of the obturator vessels and nerve, and to a slight extent from the obturator fascia, which covers the muscle.
		The fibers converge rapidly toward the lesser sciatic foramen, and end in four or five tendinous bands, which are found on the deep surface of the muscle; these bands are reflected at a right angle over the grooved surface of the ischium between its spine and tuberosity.

		The anterior portion of obturator internus was exposed by a semicircular cut along the muscle belly.
		A bursa was identified deep to the obturator internus, which facilitates the smooth gliding of the muscle.
		This theory is based on the fact that the fibers of obturator internus and the gemelli are less vertically directed than occurs with the piriformis muscle and therefore, increased hip flexion would occur before these muscles would become parallel to the femur.

		The nerve to the short head of the Biceps femoris comes from the common peroneal part of the sciatic, while the other muscular branches arise from the tibial portion, as may be seen in those cases where there is a high division of the sciatic nerve.
