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").

The dominant vascular pedicle is normally the terminal branch of the medial femoral circumflex artery, but on occasion it may arise directly from the profunda femoris artery.
The advocates of the posterior approach believe that most femoral head dislocation fall into the category of the posterior dislocation, in which the simultaneous posterior capsular lancinate usually occurred and the blood supply for the femoral head from the medial femoral circumflex artery would be destroyed.
The medial femoral circumflex artery injury is well known for being a possible complication following a femoral neck fracture, potentially leading to avascular necrosis of the femoral head and neck [5].
Anatomy of the medial femoral circumflex artery and its surgical implications.
The cruciate anastomosis involves the inferior gluteal, medial femoral circumflex, lateral femoral circumflex and the first perforating branch of the profunda femoral arteries.
The inferior division runs inferio-laterally over the gluteus minimus in the direction of the greater trochanter which anastomoses with the lateral femoral circumflex artery and with medial femoral circumflex artery to supply the hip joint (Gray).
Honing in on vascular phenomena, one study examined super-selective angiography of the medial femoral circumflex artery.
We used Smith Peterson approach to dislocate the femoral head anteriorly, thereby avoiding injury to medial femoral circumflex artery and its branches.
This is important because the medial femoral circumflex artery runs distal to this muscle.
At this point, the posterior flap contains the deep branch of the medial femoral circumflex artery (MFCA), the anastomoses with the inferior gluteal artery, and the retinacular vessels.
This ring is formed predominantly by contributions from the medial femoral circumflex artery posteriorly, with smaller contributions from the lateral femoral circumflex artery anteriorly.
Most importantly, care must be taken to preserve the medial femoral circumflex artery (MCFA) and its terminal branches to the femoral head via the lateral ascending cervical artery (Fig.
