For the treatment of ischemic necrosis of the femoral head, there are many misconceptions due to the inadequacy of physicians’ own diagnosis and treatment level: on the one hand, in order to cater to patients’ fear of surgery, conservative treatment by traditional Chinese medicine is used, resulting in many patients losing the best time for surgery to preserve the femoral head; on the other hand, many doctors perform artificial joint replacement for patients with ONFH, without On the other hand, many doctors for the ONFH patients all artificial joint replacement, and did not fully consider the age and stage of the lesion, so that the late complications are difficult to deal with. Therefore, to improve the level of diagnosis and treatment of ONFH and to strictly grasp the indications for treatment is one of the important issues that we should emphasize. The comprehensive treatment method adopted is: 1, bed, the affected limb to avoid weight-bearing skin traction for 1 month, traction weight 2-4kg, after supporting double crutches to the ground, 3 months the affected limb can not bear weight. 2.Apply anticoagulation, vasodilator and capacitating drugs intravenously with 500ml of low molecular dextrose injection, 16ml of compound danshen injection, or 10-20ug of Kaiser injection, add to saline or glucose and apply the above drugs continuously for 3 weeks. And at the same time, take Wei’s Live Bone I capsule. 3. 10 days of hyperbaric oxygen therapy is a course of treatment, which can be applied for 2-3 consecutive courses. During the treatment period, attention should be paid to oxygen toxicity and other complications. Once necrosis is found to be aggravated, conservative treatment should be abandoned immediately and surgery should be performed as soon as possible to prevent further aggravation of femoral head collapse.
