The majority of the blood supply to the femoral head comes from the medial and lateral circumflex vessels. These vessels directly branch off of which of the following?
  • Obturator artery
  • The obturator artery is a branch of the internal iliac artery and divides into an anterior and posterior branch after passing through the obturator foramen. It supplies the obturator externus, pectineus, and adductor muscles.

  • Profunda femoris
  • The profunda femoris is a branch of the common femoral artery, and supplies many different branches including the medial and lateral circumflex vessels that supply the femoral head.

  • Superior gluteal artery
  • The superior gluteal artery is a branch of the internal iliac artery, and supplies the gluteus medius and minimus muscles, as well as parts of the gluteus maximus and tensor fascia lata muscles.

  • External iliac artery
  • The external iliac artery is a branch of the common iliac artery, and divides into the inferior epigastric, deep circumflex iliac, and femoral arteries.
