Schematic representation of the arteries of the thigh

The arteria circumflexa femoris medialis ("inner artery that encircles the femur") is an artery of the lower extremity in the area of ​​the thigh .


The arteria circumflexa femoris medialis arises in humans mostly from the arteria profunda femoris , occasionally also directly from the arteria femoralis . It then runs on the inside (medial) around the shaft of the thigh bone , initially running between the pectineus and iliopsoas muscles and then between the internal obturator and adductor brevis muscles . They sent it a branch of the pelvic socket , through the acetabular notch pulls and the Ramus acetabular the obturator artery anastomoses . The continuous main trunk runs over the upper edge of the adductor magnus muscle and divides into two branches below the quadratus femoris muscle .

A branch extends headward (cranial) to the trochanteric fossa of the femur and anastomoses there with the inferior and superior gluteal arteries and the lateral circumflex artery . The second branch turns to the outside of the thigh bone and forms connections with the inferior gluteal artery and the lateral circumflex artery.

Comparative anatomy

In the other mammals, the medial circumflex artery also mostly emerges from the profunda femoris artery and extends in the direction of the long ischial muscles . In its course it divides into several branches:

  • The obturator branch runs through the obturator foramen and supplies the internal obturator muscle and external obturator muscle .
  • The Ramus acetabularis runs through the Incisura acetabuli and supplies the hip joint and the rotators of the hip.
  • The ramus profundus runs between the obturator muscle externus and the quadratus femoris muscle on the outside of the thigh bone and anastomoses there with the lateral circumflex femoral artery.
  • The ramus ascendens extends in the direction of the ischial tuberosity and supplies the adductors and the long ischial muscles.
  • The ramus transversus is the strongest branch of the vessel and takes over a large part of the blood supply to the long ischial muscles.
