		In half of the cases, the cutaneous contribution of the obturator nerve is missing or overlapped by the femoral, posterior cutaneous, or sciatic nerve; in half of the cases, hypoesthesia is either in the medial part of the knee or in the inner part of the popliteal fossa.
		The cutaneous distribution of the obturator nerve must not been assessed on the medial aspect of the thigh and the only way to effectively evaluate obturator nerve function is to assess the adductor strength [10-13].
		Obturator nerve block at the pubic level combined with spinal or general anesthesia is indicated in transurethral resection (TUR) of tumors located on the lateral and inferolateral bladder.

	Oral Cancer - Restoration / Rehabilitation
		The purpose of an obturator prostheses is to restore the physical separation between the oral and nasal cavities, thereby restoring speech and swallowing to normal, and to provide support to the lip and cheek.
		The obturator provides a matrix upon which the surgical packing can be placed, minimizes contamination of the wound in the immediate postoperative period, and enables the patient to speak and swallow effectively immediately after surgery.
		The obturator’s size is determined by the surgical boundaries of the resection, as indicated by the surgeon.

	The Physician and Sportsmedicine: Obturator Neuropathy
		However, the entrapment does not appear to occur within the fibroosseous obturator tunnel but rather at the level of the obturator foramen and proximal thigh where the fascia entraps the anterior branch of the nerve as it passes over the adductor brevis muscle.
		The typical scintigraphic appearance of obturator neuropathy, unilateral increased uptake over the pubic symphysis (figure 3), is similar to that of osteitis pubis, so scintigraphy cannot be used to distinguish the two conditions.
		We believe that obturator neuropathy is a common cause of exercise-related groin pain, particularly in those who play sports such as soccer or Australian Rules football, which involve a great deal of running, sharp twists and turns, and frequent, powerful kicks.

	[An obturator or "lateral" bypass in infected vascular prostheses in the groin?]
		The indications for obturator bypass reconstructions included: 20 infections of aorto-femoral grafts, two infected pseudoaneurysms in the groin after PTA of the superficial femoral artery, and 4 infections of iliac-femoral grafts.
		The obturator bypass was performed using a PTFE graft in 3 cases, and Dacron graft in 23.
		The donor's artery used for obturator bypass was a noninfected proximal part of aortofemoral graft in 20 cases, and iliac artery in 6 patients.

		In these the obturator arose from the hypogastric (internal iliac) in both sides in 160; from the epigastric on both sides in 56; from the epigastric on one side, and the hypogastric (internal iliac) on the othere, in 28; from the external iliac in 6.
		Monro, cited by Reid, thought the relative proportion between the origin of the obturator artery from the internal iliac and its branches, and from the epigastric and the external iliac, to be as 20 to1.
		Meckel was of the opinion that the obturator arises nearly as frequently from the the epigastric and external iliac, as from the internal iliac and its branches.

	Trocar with multiple converters and detachable obturator - Patent 5300036
		Still further, the invention provides a trocar obturator with a snap-fit joint which permits the forward portion of the obturator to be detached from the trocar body and separately used with the trocar tube subassembly.
		The distal obturator part 106 is separable from the proximal obturator part 108 by means of a male 112, female 114 snap fitting.
		The latch 116 could be configured to slightly lift the distal obturator part 106 for ease of grasping, and prevent the trocar body subassembly from attaching unless the latch were in the down and unattended position.

		The obturator internus muscle originates within the pelvis on the obturator membrane (a membrane that closes all but the superior border of the obturator foramen) and on those portions of the pubis and ischium that surround the obturator foramen.
		When viewed from the posterior or gluteal aspect, the tendon of the obturator internus is often obfuscated by the tendons of the superior and inferior gemellus muscles (the two gemelli).
		The obturator internus (also a lateral rotator of the thigh) is innervated by sacral nerves 1 and 2 through small branches of the sacral plexus.

	Oral prosthetics in managementof the head and neck cancer patient
		In addition to assessment and fabrication of obturators for the maxillectomy patient, the prosthodontist can also make suggestions to the surgeon for resections that will make the stability and comfort of the prosthesis better.
		Design of the surgical obturator is a challenge, and involves communication between the surgeon and the prosthodontist.
		Post-surgical obturators are those prosthetics which are placed immediately after packing removal, used until tissue contracture is minimal, and prior to definitive obturator placement.

	Patent 6,179,826
		The obturator may be re-inserted into the cannula after the vehicle is initially placed in the cannula to position the vehicle at the distal end.
		The obturator used for thus positioning the vehicle may be the same as or different from the obturator initially positioned in the cannula.
		The obturator is of the type designed for insertion within and along a substantial length of the cannula to prevent backfill of materials, such as dura, into the cannula during insertion of the cannula to the treatment site.

	Chevron grooved decoupling obturator (US4242961)
		An obturator for a projectile to be fired from a rifled barrel is provided in accordance with this invention, with this obturator being mounted on the projectile in such a way as to permit rotational slippage.
		The interior of the obturator ring is designed to slip rotationally with respect to the projectile body portion as the projectile travels along the barrel, thereby advantageously minimizing the rotation of the projectile as a result of rifling effects.
		One embodiment of an obturator in accordance with this invention may be designed to disintegrate as it leaves the barrel, whereas another embodiment may utilize an overwrap of high temperature filamentary material in at least some of the slots, which overwrap serves to increase the hoop strength of the obturator.

	Reference.com/Encyclopedia/Obturator internus muscle
		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.
