For unilateral lesions, the affected side should be strictly avoided, and patients can walk with crutches, sciatic brackets and walkers. If both hips are involved at the same time, stay in bed or take a wheelchair; If the hip joint pain is serious, you can stay in bed and pull your lower limbs at the same time, which can often relieve the symptoms. X-rays should be taken regularly during the treatment, and the weight can only be maintained after the lesion is completely healed.
(2) surgical treatment. At present, the commonly used surgical treatment methods in clinic are: ① drilling and bone grafting of femoral head. In the early stage of avascular necrosis of the femoral head, when the femoral head is intact and there is no "half-moon sign", drilling and bone grafting can be carried out. If the surgical indications are properly selected, it can help rebuild the blood supply of femoral head. ② Multi-vascular bundle and cancellous bone implantation. This surgical measure can achieve three purposes: rebuilding or increasing the blood supply of femoral head; Reduce intraosseous pressure; Improve venous reflux, so as to achieve its curative effect. ③ Rotational osteotomy through the rotor. This operation can relieve pain, increase joint space and prevent further collapse and dislocation for avascular necrosis of femoral head, but it is only suitable for less serious cases. ④ Hip fusion. It should be very cautious to choose hip fusion to treat avascular necrosis of femoral head. For patients with bilateral hip diseases, at least one hip joint should be kept active. If the fusion operation is successful, it can relieve the pain of hip joint, and the hip joint is relatively stable, which is suitable for standing for a long time or walking often.
⑤ Artificial joint replacement. One is artificial femoral head replacement. It is suitable for patients with femoral head collapse within a short period of onset, but secondary osteoarthritis has not yet occurred in acetabulum. Many people are satisfied with the postoperative effect, but few people are really "excellent". The second is total hip replacement. Most patients in stage Ⅲ and Ⅳ are not suitable for osteotomy because of severe pain in hip joint, obvious mobility limitation, serious collapse and dislocation of femoral head and secondary osteoarthritis of hip joint. Total hip replacement can be used. Because the pain of hip joint disappears immediately after total hip replacement, the hip joint can reach about 90 flexion and 30 abduction, so the short-term curative effect is satisfactory. It is also suitable for the treatment of patients with double hip joints. However, there are many important complications after total hip replacement, and the long-term effect needs further observation. The third is hip resurfacing. In recent years, a new treatment technique for avascular necrosis of femoral head is hip resurfacing, which brings good news to young and middle-aged patients. Because there are many long-term complications after total hip replacement, as a protective transitional treatment for young patients, some well-known foreign experts have developed the advantages that the surface of hip joint conforms to the physiological state of hip joint. In China, a group of young and middle-aged patients with avascular necrosis of femoral head were treated by hip resurfacing in the Department of Orthopaedics, Affiliated Hospital of Nantong University, and achieved good results. Especially the best choice for young and middle-aged patients
