28 patients were subjected to follow-up examination after having suffered for more than 10 years from idiopathic necrosis of head of femur. The high incidence of the bilateral affection of the hip joint as well as the occurrence of multiple osteonecroses are correlated with distrubances of lipid metabolism. Under conservative treatment the disease takes a progressive course, which, however, can remain subclinical for a long time. Good postoperative results can only be expected from intertrochanteric corrective osteotomy which often leads to a regeneration of the head of femur. Caution is recommended before confirming the indication for athrodesis or total endoprothesis because of the risk of disturbances of consolidation or loosening of the implant.
28例特发性股骨头坏死患者在患病超过10年后接受了随访检查。髋关节双侧受累的高发生率以及多发性骨坏死的发生与脂质代谢紊乱相关。在保守治疗下，疾病呈进行性发展，然而，其在很长一段时间内可能仍处于亚临床状态。只有通过转子间矫正截骨术才能期望获得良好的术后效果，该手术常可导致股骨头再生。由于存在骨愈合障碍或植入物松动的风险，在确定关节融合术或全关节置换术的适应症之前建议谨慎。
