ANFH treatment Daquan

1, osteonecrosis of the femoral head of the Drugs: Huang Jing oyster pill (Song Wanyao), Yi Gu Yu Huang Wan (Song Wanyao), the benefits of HUANG Sheng pill. 2, conservative treatment (1) to avoid loading can rely on the first cane, crutches, and other branch of the axillary, strictly limit the load, can restore blood supply to ischemic tissue, and from pressure to control diseases, the prevention of collapse, to avascular necrosis of the femoral head to Healing. But the general view that restrictions on loading and can not save ANFH's condition, the law should not apply to major surgery for the elderly, generally poor, avascular necrosis of advanced and poor prognosis of patients. And the possibility of self-healing lesions the size and distance from the proximity of the joint surface: small lesions or away from the joint surface, the more self-healing, such as lesions or lesions near the articular surface of the larger, even if it does not load, the possibility of self-healing And also very small. (2) electrical stimulation of bone successful, can promote fracture healing. Electrical stimulation of bone necrosis can be used as an independent treatment or surgery adjuvant treatment. 3, surgical treatment (1) to retain the femoral head of the treatment, apply to the early osteonecrosis of the femoral head. ① bored decompression can reduce the pressure within the bone to promote venous return, the lifting of nourishment vasospasm, angiogenesis can be bone-long one-ischemic. Mainly used for the early collapse of the joint surface without patients, the treatment of bone necrosis is the simplest method. ② bone graft because of the need to pre-drilling, drilling is also known as decompression and operation. Existing drilling decompression, bone graft to provide mechanical support, with another increase muscle pedicle bone graft femoral head of the blood supply. ③ osteotomy for the shares by changing the femoral head and backbone of the corresponding position, to increase the weight-bearing area of the femoral head, reducing the pressure on the femoral head, will be out of focus ANFH loading zones, thus reducing local bear the stress, at the same time, Osteotomy for the marrow and opening up, can reduce the pressure within the bone, the femoral head to improve the blood circulation. (2) Arthroplasty Applied to the articular surface of the femoral head collapse necrosis patients, viable metal cup arthroplasty, joint replacement operation, the femoral head replacement, total hip replacement, and so on.
