Medial circumflex femoral artery
（重定向自Medial femoral circumflex artery）
The medial circumflex femoral artery (internal circumflex artery, medial femoral circumflex 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 (ischemic) of the femoral neck/head.
