The treatments for stage I necrosis of femoral head include general treatments such as weight reduction and alcohol cessation, drug treatments such as NSAIDs, and surgical treatments such as medullary decompression. 1. General treatment: When the necrosis of the femoral head is in the first stage, it is necessary to support the crutches to reduce the weight-bearing, and to control the weight when the weight is too big. At the same time, pay attention to rest and quit drinking as soon as possible. 2. Drug treatment: Stage I necrosis of the femoral head is usually treated conservatively, and heparin, prostaglandin and other anticoagulant and vasodilator drugs can be used as prescribed by the doctor to promote the recovery of blood flow in the necrotic part of the femoral head. Anti-osteoporosis and non-steroidal anti-inflammatory drugs such as alendronate and celecoxib can also be used to prevent osteoporosis, reduce pain and relieve symptoms. 3. Surgery: Patients with stage I necrosis of the femoral head who have failed to receive conservative treatment can choose surgery, such as core decompression surgery and bone grafting surgery to remove the lesion. Patients with necrosis of the femoral head need to be examined and evaluated by a doctor to choose the appropriate treatment, so as not to delay the condition.
