Obturator internus: Attachments, innervation and action

Obturator internus muscle (Musculus obturator internus) Obturator internus is a bilateral triangular-shaped muscle situated deep within both the pelvic and gluteal regions. This muscle is primarily considered a muscle of the lower limb The obturator internus (also known as internal obturator, internal obturator muscle, obturator internus muscle, latin: musculus obturatorius internus) is a muscle of the posterior muscle group of the pelvic girdle.. Origin. The obturator internus originates in the lesser pelvis from the internal surface of the obturator membrane.. Insertion. The obturator internus exits the lesser pelvis via. The obturator internus extends from ischiopubic ramus and posterior surface of the obturator membrane, to the medial surface of the greater trochanter of fem..

The Obturator Internus (Or OI, as they are known by friends) is a muscle that lives inside your pelvis in the obturator foramen and attaches to the hip via the greater trochanter. You can see it here: The OI has several major functions for the body. First, it is a deep hip external rotator, and has shown to be active during the movements of hip. Dan Hellman demonstrates how to segmentally strengthen the obturator internus. This muscle is extremely important for the pelvic floor and for sports functi.. Pelvic floor muscle rehabilitation is a widely utilized, but often challenging therapy for pelvic floor disorders, which are prevalent in older women. Regimens involving the use of appendicular muscles, such as the obturator internus (OI), have been developed for strengthening of the levator ani muscle (LAM)

Medical definition of obturator internus: a muscle that arises from the margin of the obturator foramen and from the obturator membrane, that inserts into the greater trochanter of the femur by way of tendons passing through the greater sciatic foramen, and that acts to rotate the thigh laterally when it is extended and to abduct it in the flexed position Obturator Internus . The Obturator Internus is a muscle of the gluteal region. Anatomical Attachments: Origin: Arises from the greater sciatic notch and the inner surface of the obturator foramen as well as the obturator membrane. Insertion: Attaches to the greater trochanter of the femur Obturator internus muscle (OIM) abscess occurs rarely in adults. Accurate diagnosis is often hindered and delayed due to the deep location of the abscess and the nonspecific clinical features. Even of rarer occurrence is rupture of the obturator internus muscle abscess into the perirectal space and retroperitoneum causing extensive retroperitoneal necrotizing soft tissue infection 1. Introduction. Obturator internus muscle abscess occurs rarely in adults. Most of the reported cases of obturator internus muscle abscesses affected children [].To my knowledge, there are only six reported cases of obturator internus muscle abscesses in adults [].Even of rarer occurrence is rupture of the obturator internus muscle abscess into the perirectal space and retroperitoneum causing. Background: The superior gemellus, inferior gemellus, and obturator internus muscles were once regarded as a single muscle judging from their insertion and function.However, current textbooks of anatomy do not treat them as one muscle. In gross anatomy, the classification of muscles depends largely upon the nerve supply, so that the present author re‐examined the nerve supply to the three.

Buttock pain is a relatively common complaint among adolescent athletes and can have a very broad differential diagnosis.The authors present a previously unreported case of acute obturator internus and obturator externus strain in an adolescent male American football player. The diagnosis was made by MRI. The patient was treated with relative rest, physical therapy, and gradual return to. The obturator internus muscle is found on the superior inner side of the obturator membrane. The obturator internus muscle originates from the inferior margin of the superior pubic ramus and from the pelvic surface of the obturator membrane. Its tendon exits the pelvis through the lesser sciatic foramen to insert onto the greater trochanter of the femur to laterally rotate the thigh. This muscle is innervated by the obturator internus nerve (L5-S2) The nerve to obturator internus originates in the sacral plexus. It arises from the ventral divisions of the fifth lumbar and first and second sacral nerves . It leaves the pelvis through the greater sciatic foramen below the piriformis muscle, and gives off the branch to the gemellus superior , which enters the upper part of the posterior surface of the muscle Abstract. A 28-year-old male rugby player presented with severe onset of right hip pain when he fell awkward after a ruck during an international match. A rare case of an acute strain of the obturator internus muscle, a deep muscle of the hip joint, is reported, which resolved completely after a period of rest and intense active physical therapy Dan Hellman demonstrates how to segmentally strengthen the obturator internus. This muscle is extremely important for the pelvic floor and for sports functio..

  3. The obturator internus tendon (star) is composed of tightly packed collagenous fibers in panel B, but the fibers becomes sparse near the greater trochanter (panels E-I). The gemellus muscles (GS, GI) have a thick fascia (arrows in panels D and E) facing the sciatic nerve (SN)
  4. The Vastus internus (m. vastus medialis) arises from the lower half of the anterior intertrochanteric line, the inner lip of the linea aspera, the upper part of the internal supracondylar line, the tendon of the Adductor magnus, and FEMORAL ARTERV -eMORAL NERVE BRANCHES OF OBTURATOR NERVE
  5. (2) The gemelli formed a muscular pocket (gemellus pocket) through which obturator internus muscle passed. Conclusions : In light of this knowledge on nerve muscle relationships, the difference in the pattern of nerve supply to the superior gemellus, inferior gemellus, and obturator internus muscles cannot be the basis for stating that the muscle are independent

The obturator internus tendon sheath and bursa were injected with 2.5 ml of 0.5% lidocaine combined with 10 mg of triamcinolone. The patient reported immediate complete relief of pain with continued relief at 2 and 6 months post-injection The Obturator internus is situated partly within the lesser pelvis, and partly at the back of the hip-joint. It arises from the inner surface of the antero-lateral wall of the pelvis, where it surrounds the greater part of the obturator foramen, being attached to the inferior rami of the pubis and ischium, and at the side to the inner surface.

And it has many important fascial connections I actually recently worked with somebody who has kind of sit bone pain going on. We also checked their obturator internus and externus, but what we found, in their case, and I'm kind of leaning this way for your description as well, is gluteus minimus, and especially the trigger points from gluteus minimus which refer towards the sit bone and close to the center line, even near the sacrum there Sir.—To our knowledge, primary infection of the obturator internus muscle (OIM) has not been previously reported.

The obturator internus muscle originates within the pelvis on the obtu-rator membrane, a membrane that closes all but the su-perior border of the obturator foramen, and on those portions of the pubis and ischium that surround the ob-turator foramen. It is a lateral rotator of the thigh. Al The obturator externus muscle covers the outer surface of the pelvis. The muscle is flat and fan-shaped. It lies deep in the medial compartment of the thigh (the inner thigh) and is only visible. The obturator internus (OI) muscle is important in adult chronic noninfectious pelvic, perineal, gluteal, and retrotrochanteric pain syndromes.
