The nerve to obturator internus (also known as the obturator internus nerve[citation needed]) is a mixed (sensory and motor)[1] nerve providing motor innervation to the obturator internus muscle and gemellus superior muscle,[2][1] and sensory innervation to the hip joint.[1] It is a branch of the sacral plexus. It is one of the group of deep gluteal nerves.[2]
It exits the pelvis through the greater sciatic foramen to innervate the gemellus superior muscle, then re-enters the pelvis to innervate the obturator internus muscle.[2]
