When does necrosis of the femoral head require artificial replacement? What is necrosis of the femoral head related to? Necrosis of the femoral head is one of the most common orthopedic diseases. Although there is no clear explanation for the cause of femoral head necrosis, it is known that excessive alcohol consumption, hormone abuse and fracture of the femoral neck are important factors leading to femoral head necrosis. The main treatments for osteonecrosis of the femoral head are conservative treatment and surgery. The specific treatment is different from person to person. What are the conditions that require artificial replacement? Is it necessary to have joint replacement as long as you have necrosis of the femoral head? Here we will introduce How to determine the need for artificial joint replacement for necrosis of the femoral head? Necrosis of the femoral head is categorized into 5 stages in medicine. If you are unfortunate enough to suffer from necrosis of the femoral head, you must go to a regular hospital for examination, and not all patients need to be treated with artificial joint replacement. If the patient is not treated in the right way after being detected with necrosis of the femoral head, the patient’s condition will gradually develop to an advanced stage, which will lead to the collapse of the femoral head. Stage 1 femoral head patients may experience different degrees of pain in the hip joint, and necrosis cannot be accurately detected by X-ray and CT examination alone. In patients with stage II femoral head, signs of osteonecrosis can be detected through X-ray, and the femoral head is not deformed at this time. Therefore, these two conditions basically do not affect the normal function of the hip joint, and most of them can save the femoral head through treatment. If the patient’s femoral head necrosis has developed to stage 3, through timely treatment, it is possible to retain most of the functions of the hip joint, and it is very hopeful that the femoral head can be preserved. Generally, if the patient is in the late stage III, IV or V of femoral head necrosis, and the femoral head has collapsed, then the patient needs to be treated by artificial joint replacement. If the patient is under 50 years of age, he or she may choose to have the surface of the femoral head replaced, as this type of surgery preserves the bone for future revision surgery. If the necrosis of the femoral head has reached an advanced stage, doctors basically recommend that the patient undergoes artificial joint replacement surgery to improve and restore the patient’s health. There are advantages and disadvantages of artificial joint replacement. The advantage of artificial joint replacement is that it can restore the function of the hip joint compared to other treatments, while the disadvantage is that it is more expensive and needs to be replaced when it reaches the end of its life span because the life span of the artificial joint is certain.
