Necrosis of the femoral head is very difficult to realize the cure, the necrotic bone is irreversible, some patients may realize the cure through decompression and bone grafting and other surgeries, but the efficacy is not exact. Necrosis of the femoral head is caused by ischemic necrosis of the femoral head, cystic degeneration of the femoral head, and severe cartilage collapse due to trauma, alcohol consumption, or hormone application. Before the third stage of femoral head necrosis, the surface of the femoral head is not completely collapsed, by taking decompression and bone grafting and other hip preservation surgical treatments, some patients can realize healing, but the curative effect is not exact. If the femoral head ischemic necrosis is above the third degree, the femoral head has already collapsed, it is difficult to realize the cure, and can only take the artificial femoral head replacement in order to relieve the pain and activity limitation. Therefore, early necrosis of the femoral head should be consulted in time and treated with medication, physical therapy or hip-preserving surgery as prescribed by the doctor. If these methods are not effective, then consider hip replacement surgery.
