目前对股骨头缺血性坏死治疗的困惑和矛盾很大程度上是由于缺乏一致的有效、定量的评估和分期系统造成的。我们在12年的时间里使用了一个新的系统来评估超过1000个股骨头缺血性坏死的髋关节；事实证明它非常有价值。该系统基于已知发生的病理事件的顺序，它允许在早期和晚期阶段进行准确的量化，不使用旧的侵入性诊断程序，并结合了骨扫描和 MRI 等较新的技术。疼痛和功能下降的临床记录虽然有助于确定治疗和结果，但并不是系统的特定部分。根据放射学变化的类型，首先将髋部分为从 0 到 VI 的七个阶段之一，然后测量受累程度，这可以更准确地评估进展或缓解情况，并更好地比较不同的治疗方法。该系统还有助于提供预后并决定最佳的治疗方法。
Much of the current confusion and contradiction on the treatment of avascular necrosis of the femoral head is caused by the lack of an agreed efficient, quantitative system for evaluation and staging.We have used a new system to evaluate over 1000 hips with avascular necrosis during a period of 12 years; it has proved to be very valuable.The system is based on the sequence of pathological events known to take place, It allows accurate quantification in both early and later stages, does not use older, invasive diagnostic procedures, and incorporates the newer techniques of bone scanning and MRI. Clinical records of pain and reduced function are not a specific part of the system, although they help to determine treatment and outcome.Hips are first placed into one of seven stages from 0 to VI, based upon the type of radiological change, The extent of involvement is then measured, This allows more accurate evaluation of progression or resolution and better comparison of different methods of management. The system also helps to provide a prognosis and to decide on the best available method of treatment.
