medial circumflex femoral artery


Also found in: Wikipedia.

me·di·al cir·cum·flex fem·o·ral ar·ter·y

[TA]
artery that, with the lateral circumflex femoral artery encircles the proximal femur and is the primary blood supply of the femoral head and neck; origin, profunda femoris; distribution, hip joint, muscles of thigh; anastomoses, inferior gluteal, superior gluteal, lateral circumflex femoral (so-called "cruciate anastomosis").

medial circumflex femoral artery

an artery that passes medially around the shaft of the femur and near the margin of the adductor brevis, giving off a small branch, which enters the hip joint through the acetabular notch and anastomoses with the acetabular branch of the obturator artery, then divides into two major branches deep to the quadratus femoris muscle. One of these branches ascends to the trochanteric fossa and connects with branches of the gluteal and lateral circumflex femoral arteries. The other branch passes laterally to participate with other arteries to form an anastomotic network of vessels around the hip.

The second instance was anterior to the proximal part of the adductor magnus muscle, where the posterior division is crossed by the arterial anastomosis between the muscular branches of the medial circumflex femoral artery and the anterior branch of the obturator artery (Figure 4).
A branch enters the trochanteric fossa to join the inferior gluteal artery and ascending branch of the medial circumflex femoral artery while other branches run through gluteus minimus muscle to supply the hip joint (Standring).
