Artery of the Femoral Head Posterior Lateral

Artery of the Head of the Femur Posterior Lateral: Anatomy and Role in Blood Circulation

The artery of the femoral head is the posterior lateral, also known as a. capitis femoris posterior lateralis is an important vessel providing blood supply to the femoral head. In this article we will look at the anatomy of this artery and its role in blood circulation.

Anatomy:
The posterior lateral femoral head artery originates from the iliopsoas artery, which is a branch of the external iliac artery. After leaving the original vessel, the posterior lateral artery of the femoral head goes to the femoral head, passing along the posterior and lateral surface of the thigh.

Role in blood circulation:
The posterior lateral artery of the femoral head is one of the main arteries responsible for the blood supply to the femoral head. The femoral head is part of the femur and plays an important role in maintaining the stability and functionality of the hip joint.

Blood entering the femoral head through the posterior lateral femoral head artery provides essential nutrients and oxygen needed for healthy bone function. In addition, this artery plays an important role in draining waste blood and metabolic waste from the tissues of the femoral head.

Pathologies and risks:
Disruption of the blood supply to the femoral head can lead to serious consequences, such as necrosis of the bone tissue of the femoral head. This condition, known as osteonecrosis of the femoral head, can cause pain and dysfunction of the hip joint.

A number of factors can contribute to the development of osteonecrosis of the femoral head, including trauma, arterial disease, poor circulation, and long-term use of certain medications. Therefore, it is important to maintain the health of the posterior lateral femoral head artery and ensure normal blood supply to the femoral head.

Conclusion:
The posterior lateral femoral head artery plays an important role in the blood circulation of the femoral head. Maintaining normal blood flow to this area is key to maintaining hip health and function. Understanding the anatomy and role of this artery helps doctors and healthcare professionals effectively diagnose and treat associated pathologies, as well as take steps to maintain the health of the femoral head and reduce the risk of developing osteonecrosis.

Artery of the femoral head, lateral posterior, or a. caput femoris lateralis anteroposterior, a. cephalis femuris, - anterior and posterior arteries arising from the internal iliac artery. It passes through the greater sciatic foramen in the corpus cavernosum and is located on the back of the thigh. The artery supplies blood to the hip joint and surrounding area. *The artery is formed by:* the anteromedial and small branches of the perineal artery, supplying the large vessel-tempo, located in the interpubic bone, which arises from the superior pubic vein.

*Type of blood supply:* The anterior and posterior arteries of the femoral neck, passing through the deep sciatic ring, supply blood to the pelvic triangle, the upper parts of the medial, lateral suprapubic quadrates and spaces; the femoral head is supplied by two branches of the anastomotic artery to the femoral neck.

***Blood supply (List of terms from the anatomy textbook):*** The femoral head is supplied through the head and body of the femur by branches of the femoral artery. In children a. thomis transmits nutrition to the distal part of the body of the femur and gluteal bones. Between the endostosis and the external head of the femoral muscle, the vessel turns into the superficial femoral artery to supply the skin and subcutaneous tissue in the entire thigh, excluding the lateral surface. For these purposes, the aa capititas femoris is divided into two branches, one terminal for the posterior body of the femur, and the other branch divided under the Poupart triangle into the anterior tibia and posterior tibia. The latter is called the onion branch. *Synonyms:* AA Capitatis Femoris Antero-Posterior.

Some features:

1. The main pathology of the branches of the femoral neck is diastasis between the femoral neck and the seat, which is characterized by a persistent widening of the interosseous gap in the area of ​​the articular sac. The defect is accompanied by compensatory hypertrophic thickening of the umbilical region, causing a narrowing of the femoral-ischial joint. 2. Compression syndrome or confusion syndrome
