Artery: Posterior branch of the obturator artery

The posterior branch of the obturator artery follows the posterior margin of the foramen and turns forward on the inferior ramus of the ischium, where it anastomoses with the anterior branch.

It gives twigs to the muscles attached to the ischial tuberosity and anastomoses with the inferior gluteal.

It also supplies an articular branch which enters the hip-joint through the acetabular notch, ramifies in the fat at the bottom of the acetabulum and sends a twig along the ligamentum teres to the head of the femur.
