Our goal in the treatment of avascular necrosis is to retard or reverse the progressive changes that normally take place and thus preserve rather than replace the femoral head. "Conservative" or nonoperative management has generally proved unsuccessful, and results with established surgical procedures have been inconsistent and frequently disappointing. A new approach has been described that uses direct-current stimulation in conjunction with bone grafting and decompression. Results were determined clinically and radiographically using a new method of staging and evaluation. The majority of patients who underwent surgery showed significant clinical improvement, especially in regard to pain relief. Some degree of radiologic progression, however, was detected in most cases, even in many with clinical improvement. Electrical stimulation, as used in this study, did not appear to alter the results obtained with decompression and grafting alone. It must be emphasized that this is a preliminary report. More data and longer follow-up will be required before definitive conclusions can be drawn, and we must continue our efforts to improve the management of avascular necrosis.
我们治疗股骨头缺血性坏死的目标是延缓或逆转通常发生的渐进性变化，从而保留而非置换股骨头。“保守”或非手术治疗通常已被证明是不成功的，既定手术程序的结果也不一致且常常令人失望。一种新的方法已被描述，即结合骨移植和减压使用直流电刺激。使用一种新的分期和评估方法从临床和影像学上确定结果。大多数接受手术的患者显示出显著的临床改善，尤其是在疼痛缓解方面。然而，在大多数病例中，即使在许多临床有改善的患者中，也检测到了一定程度的放射学进展。本研究中使用的电刺激似乎并未改变单独减压和植骨所获得的结果。必须强调的是，这是一份初步报告。在得出明确结论之前，需要更多的数据和更长时间的随访，而且我们必须继续努力改进股骨头缺血性坏死的治疗。
