Medial circumflex femoral artery
The medial circumflex femoral artery is an artery in the upper thigh that helps supply blood to the neck of the femur. Damage to the artery following a femoral neck fracture may lead to avascular necrosis of the femoral neck/head.Structure
The medial femoral circumflex artery arises from the medial and posterior aspect of the profunda femoris artery, and winds around the medial side of the femur, passing first between the pectineus and iliopsoas muscles, and then between the obturator externus and the adductor brevis muscles.
The medial femoral circumflex artery may occasionally arise directly from the femoral artery.Branches
At the upper border of the adductor brevis it gives off two branches:
