The fact that the necrosis of the femoral head has not progressed is not considered a cure, only a control of the condition. The femoral head is an important part of the hip joint, usually located in the acetabular fossa, and when affected by certain factors, ischemic necrosis of the femoral head can occur. Necrosis of the femoral head is a difficult disease to treat. Necrosis of the femoral head can be slowed down by some methods, but the lack of development does not mean that it has been cured. After the treatment of necrosis of the femoral head, there are no obvious clinical symptoms, which may be due to the medication to get the condition under control. Although there is no pain and other discomfort and the condition is no longer developing, the condition still exists. In the early stage of necrosis of the femoral head, conservative treatment can be carried out, and some drugs such as prostaglandin and warfarin can be taken to reduce the symptoms and control the development of the disease. If it develops to the advanced stage, only surgical treatment such as hip replacement can be carried out. It is recommended to cooperate with doctors to improve the quality of life.
