The Obturator Internus fascia form's Alock's Canal, which houses the pudendal nerve and vessels. When this muscle becomes overactive or too tight symptoms of pudendal neuralgia can develop. People may feel shooting, stabbing, burning, or itching in the genitals, perineum, and/ or anus. Many people with OI dysfunction also have pelvic floor. The obturator internus (OI) is a hip muscle that originates deep within the pelvis, wraps out and inserts on the posterior aspect of the head of the femur (the thigh bone). The OI's main function is to rotate the leg externally but is also has a major role in stabilizing the head of the femur into the hip socket for activities such as walking. The fascia of the obturator internus muscle is medially related to the obturator artery and nerve, as they run anteroinferiorly from the anterior trunk on the lateral pelvic wall to the upper part of the obturator foramen. The word obturator comes from the Latin word obturo, which means "to stop or block up." This adequately illustrates the location of the obturator muscles since they cover the opening of the obturator foramen. Both the obturator externus and obturator internus are bilateral-triangular shaped muscles. Generally, they originate from the obturator membrane and pelvic bone and attach to the.

The obturator internus is a muscle of the gluteal region in the lower limb. It forms part of the lateral wall of the pelvic cavity. Attachments: Originates from the pubis and ischium at the obturator foramen.It travels through the lesser sciatic foramen and attaches onto the greater trochanter of the femur. The internal obturator muscle or obturator internus muscle originates on the medial surface of the obturator membrane, the ischium near the membrane, and the rim of the pubis.. It exits the pelvic cavity through the lesser sciatic foramen.. The internal obturator is situated partly within the lesser pelvis, and partly at the back of the hip-joint.. It functions to help laterally rotate femur. A small case series has described obturator internus muscle injury occurring alongside injury of other gluteal muscles after posterior hip dislocation secondary to trauma [4]. We describe 2 cases of obturator internus strain in high level young male athletes involved in kicking sports. The obturator nerve arises from the lumbar plexus and provides sensory and motor innervation to the thigh. This nerve provides motor innervation to the medial compartment of the thigh and as a result, is essential to the adduction of the thigh. The nerve provides sensory innervation to the medial upper thigh and provides articular branches to the hip and knee. The obturator nerve is clinically.

The nerve to obturator internus (also known as the obturator internus nerve [citation needed]) is a mixed (sensory and motor) nerve providing motor innervation to the obturator internus muscle and gemellus superior muscle, and sensory innervation to the hip joint. It is a branch of the sacral plexus.It is one of the group of deep gluteal nerves. It exits the pelvis through the greater sciatic. Obturator internus. Origin. Internal surface of obturator membrane and posterior bony margins of obturator foramen. Insertion. Medial surface of greater trochanter of femur, in common with superior and inferior gemelli. Action. Rotates the thigh laterally; also helps abduct the thigh when it is flexed. Innervation. Obturator internus is a muscle that is situated deep to gluteus maximus, gluteus minimus, and gluteus medius in the gluteal region. It is one of six deep lateral hip rotators which aid in hip stabilization and movement when walking, running, and standing. Due to its function as a hip stabilizer, obturator internus is essential for preventing. 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.

The obturator nerve is a major peripheral nerve in your thigh. It's responsible for some leg movements (motor function) as well as sensation (sensory function). This nerve is formed by portions of the lumbar plexus, which is a complex network of nerves that emerge from the lumbar region of the spine, which is in your lower back. The obturator internus muscle, like the piriformis muscle, is both a muscle of the pelvic wall and of the gluteal region.It originates within the pelvis, and continues as a flattened tendon posteriorly through the lesser sciatic foramen (between ischial spine and tuberosity).. Summary. origin. anterolateral wall of true pelvis; deep surface of obturator membrane and pelvic surfaces of pubis.
