Description[edit | edit source]
The obturator internus muscle of lateral wall of pelvis and found on the superior inner side of the obturator membrane.[1]
Origin[edit | edit source]
The obturator internus muscle originates from the inferior margin of the superior pubic ramus and from the pelvic surface of the obturator membrane.
Insertion[edit | edit source]
Its tendon exits the pelvis through the lesser sciatic foramen to insert onto the greater trochanter of the femur
Nerve[edit | edit source]
innervated by the obturator internus nerve (L5–S2).
Artery[edit | edit source]
Function[edit | edit source]
- laterally/ externally rotates the hip
- abduction of hip
- hip joint stabilizer(only when torques are applied in the specific directions in which the muscle is active.)[3]
