The obturatorius externus is a flat triangular muscle covering the wall of the pelvis. It originates from the lower half of the obturator foramen. The muscle fibres converge into a tendon which runs across the back of the hip joint and inserts in the femur. It is innervated by the obturator nerve and supplied by the obturator artery and the internal circumflex artery. This muscle rotates the femur outward. Research Obturator Externus
