Femoral head structure

The femoral head is related to people's normal ability to move. There are many diseases related to the femoral head clinically. The femoral head is also a part of the body, but most people do not know much about the specific structure of the femoral head. Many femoral head diseases are caused by abnormal femoral head structure, so it is very necessary to properly understand the structure of the femoral head. The following is a detailed introduction for you.

1. The femoral head is round, occupying about 2/3 of a sphere, and is completely covered by articular cartilage. There is a small depression at the top slightly behind it, called the femoral head fossa, which is the attachment site of the femoral head ligament, and the femoral head can obtain a small amount of blood supply from it. 2. The femur is the most important bone in the human body, and the femoral head is even more important. People's upright walking, activities, and labor all rely on the supporting function of the femoral head. Therefore, the femoral head is also the most vulnerable part.

3. Femoral head ligament: located inside the joint, connecting the femoral head fossa and the transverse ligament of the acetabulum, covered by synovium, and contains blood vessels that nourish the femoral head. When the thigh is semi-flexed and adducted, the ligaments are tight, and when it is abducted, the ligaments are loose. 4. The femorotibial joint is a ball and socket joint, and the femorotibial joint is a trochlear joint. The two together form a trochlear ball and socket joint. Judging from the morphology of the joint surface, the head of the joint is much larger than the socket of the joint, which can cause instability in the knee joint. At the same time, because the knee joint is located between the two largest bone levers in the body, the femur and the tibia, it is subject to forces in different directions when standing, walking, running, and jumping, thus easily causing joint injuries.

5. The main blood vessels supplying the femoral head include the medial femoral circumflex artery, lateral femoral circumflex artery, obturator artery, superior gluteal artery, inferior gluteal artery, and iliac lumbar artery. Avascular necrosis of the femoral head is a common orthopedic disease with a high disability rate. Interventional treatment of ANFH involves direct administration of medication through the deep femoral artery to the medial femoral circumflex artery or the lateral femoral circumflex artery using femoral artery catheterization under X-ray television.
