What are the causes of avascular necrosis of the femoral head?

Children show necrosis of the femoral head, which is normally caused by traumatic hormones and other factors. Patients show pain in the groin area, shortening of limbs, and difficulty walking. Diagnosis is made by imaging the tumor, and patients are examined physically to determine the severity of the disease, or by laboratory tests. During the treatment of femoral head necrosis, we should maintain a good lifestyle, formulate a reasonable treatment plan according to the condition, and improve the quality of life through effective treatment. In daily life, we should monitor the recovery of the disease and use auxiliary tools to walk.
