The arteria circumflexa femoris medialis, also known as the medial circumflex femoral artery, is a blood vessel located in the lower extremities of the human body. It is a branch of the deep artery of the thigh, which itself arises from the femoral artery.
This artery travels along the medial (inner) side of the thigh, supplying oxygenated blood to various structures in the region. It courses around the femur bone, specifically the neck of the femur, before reaching its destinations.
The main role of the arteria circumflexa femoris medialis is to provide a crucial blood supply to the hip joint. It forms several anastomoses (connections) with other arteries in the area, ensuring efficient circulation and vascular support for the surrounding tissues.
In addition to the hip joint, this artery also supplies blood to the muscles and soft tissues of the upper thigh, including the adductor muscles responsible for leg adduction. It may give off branches, such as the articular branches, which supply blood to the hip joint's capsule and ligaments.
Pathological conditions affecting the arteria circumflexa femoris medialis, such as blockages or injuries, can have serious consequences. Reduced blood flow to the hip joint may lead to avascular necrosis (tissue death) of the femoral head, ultimately resulting in hip joint degeneration and impaired mobility. Surgical procedures involving the hip joint must carefully consider the preservation and protection of this artery to ensure adequate blood circulation and patient recovery.
