Intertrochanteric osteotomy is an effective surgical option in certain well-selected cases of osteonecrosis of the femoral head. The size of the lesion on plain radiographs in the anteroposterior and lateral projections is a critical determinant of success. The best candidates are patients with less than 50% of head involved in the necrotic sector. Collapse of the femoral head is not a contraindication to osteotomy. Location of the necrotic sector determines whether varus, valgus, flexion, or extension are most appropriate alone or in combination.
粗隆间截骨术在某些精心挑选的股骨头坏死病例中是一种有效的手术选择。前后位和侧位平片上病变的大小是手术成功的关键决定因素。最佳候选者是坏死区域累及不到50%股骨头的患者。股骨头塌陷并非截骨术的禁忌证。坏死区域的位置决定了单独或联合应用内翻、外翻、屈曲或伸展截骨术是否最为合适。
