Femoral head necrosis is a common disease in orthopedics, and if not treated properly, it may lead to limitation of hip joint movement and affect the normal life and work of the patient. In the treatment, we should first clarify the cause and stage of the disease, and accept the best treatment plan with our physical condition. Conservative treatment includes: first of all, stop taking hormones, stop drinking alcohol and other treatment for the cause of the disease. Secondly, we should take non-steroidal anti-inflammatory drugs to relieve pain and promote repair; improve local microcirculation through anticoagulants and microvascular dilating drugs; prevent femoral head collapse by taking drugs to regulate bone metabolism; and take oral Chinese medicine at an early stage to activate blood circulation and reduce symptoms. In addition physiotherapy is also very helpful in relieving the disease and improving the quality of survival of patients. Patients use double crutches, which can limit the weight-bearing of the joint and help relieve the condition. Performing hip training can help improve the function of the hip joint. External shock waves and high-frequency magnetic fields can also be used to treat femoral head necrosis. For some patients who do not have good results with medication and physical therapy, surgical treatment can be used to help improve the patient’s condition. Commonly used surgical methods include hip arthroplasty, bone grafting, osteotomy and so on. According to the patient’s condition, the best treatment method is chosen to help maintain the normal physiological function of the hip joint and improve the patient’s quality of life.
