Although necrosis of the femoral head is an irreversible disease, there are many treatment methods that are salvageable and curable. Conservative treatment in the early stage of the disease can lead to complete remission or cure, and femoral head replacement or total hip replacement is also feasible in the late stage. In the early stage, when the femoral head has not collapsed and the articular cartilage surface is more intact, conservative treatment can be actively given, such as improving lifestyle, quitting smoking and alcohol, avoiding long-term use of hormones. Oral lipid-lowering drugs and anticoagulants such as atorvastatin and low molecular heparin can be taken, and physiotherapy such as hyperbaric oxygen and shock wave can also be performed. In the late stage of necrosis, the femoral head has collapsed and the articular surface has disappeared, it is better to perform femoral head replacement or total hip arthroplasty, which almost does not affect the normal hip function after recovery and is almost indistinguishable from normal people. If the necrosis is at the end stage, and the necrosis involves the femoral stem, it is usually necessary to remove the necrotic bone by surgery, and then carry out bone grafting, and fix the necrotic position of the bone through internal fixation, so as to restore the original function by itself. When femoral head necrosis occurs, the most important thing is to treat and deal with it in a timely manner, and you should seek medical treatment in time and avoid delaying the condition. Pay attention to cultivate correct walking and running posture, do not overload. The above drugs should be applied according to the doctor’s prescription.
