Ischemic necrosis of the femoral head is a chronic and difficult disease in orthopaedics. Treatment requires a time process of necrotic bone resorption and excretion and new bone regeneration. Patients are advised not to be in an eager mood and blindly pursue the rapid effect, which is accomplished by high doses of painkillers in many clinical treatments. However, the treatment of osteonecrosis is most contraindicated by steroidal painkillers, because it causes calcification embolism, conceals the development of the disease, and gives patients the illusion that behind the rapid pain relief is a serious deterioration of the bone structure, and there is a rapid effect of a phase after which the re-photograph shows the formation of a large area of cystic necrosis inside the bone. Many patients with the mentality of quick treatment and quick cure, seeking everywhere to receive the rapid effect of medicine, the result is that the treatment for years, spending tens of thousands of dollars, the treatment to the extent that the crutches can not walk, the loss of the best treatment conditions, resulting in lifelong sorrow!
