Can children's brittle bones necrosis? How is that possible? Doctors said that a disease called "avascular necrosis of the femoral head in children" often attacks children aged 4 to 9 years. This is a problem that may occur in the growth process of children due to incomplete development, which is much better than "adult avascular necrosis of the femoral head". It's just that parents should find out the abnormal symptoms of their children in time.

　　 Typical symptoms: knee pain+limping

Zeng Yirong, deputy director of the Department of Arthrology of the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine, said that the blood supply of the femoral head (thigh bone) of children before the age of 8 was mainly provided by one blood vessel. Children at this stage, especially boys, like running, jumping, jumping and other activities. If the amount of exercise is too large or the hips are injured, the blood vessels may be damaged, Causes partial or complete interruption of blood supply to the femoral head. The result may lead to avascular necrosis of the femoral epiphysis.

Children suffering from this disease will have persistent knee pain, accompanied by lameness. Why does the disease of femur cause knee pain? Zeng Yirong said that the human body is a whole. After avascular necrosis of the femur, local blood supply insufficiency affects the obturator nerve, which of course first causes pain in the knee below the femur. This kind of pain will be aggravated when running and walking too much, but the pain symptoms can be relieved after rest, so abnormal symptoms are often ignored.

　　 It's much easier to deal with than adult problems

Don't worry, avascular necrosis of the femoral head in children and necrosis of the femoral head in adults are two completely different diseases. Adult onset often leads to severe hip joint (waist) dysfunction, which is one of the intractable diseases, while children can be cured.

Once the disease is diagnosed, it needs to be treated as soon as possible, and surgery is not needed in the middle and early stages. Use medical means to eliminate the adverse factors affecting the development of the femoral head epiphysis, prevent or reduce the secondary malformation of the femoral head and hip osteoarthritis, so that the necrotic femoral head can successfully complete its self repair process.

For late stage children, if there is dislocation of the femoral head, surgery (pelvic osteotomy) is needed, and the effect is still good. However, if it is not treated all the time, the child's body has been in the process of development, and after the healing of the disease, it may leave varying degrees of deformity and joint movement disorders.
