How to cure necrosis of the femoral head

Femoral head necrosis can be divided into 4 stages. Early treatment can relieve the degree of femoral head necrosis in patients with stage I and stage II. Decompression can be used to relieve the pressure on the affected part in stage I. Surgical transplantation is required to replace the internal head in stage II. Artificial joint replacement is required in patients with stage III and stage IV.
