To date, there is no completely satisfactory method for the treatment of osteonecrosis of the femoral head. "Conservative" management leads to a high failure rate, and surgical results have been inconsistent and disappointing. The study described in this article seeks to evaluate the role of electrical stimulation in conjunction with decompression and bone grafting. A total of 82 hips have been included to date, of which 42 with a minimum follow-up of 1 year have been evaluated. Pain relief and improved function have been noted in the majority of hips operated on, both with and without electrical stimulation. Careful radiologic assessment using a comprehensive new method of evaluation has shown some degree of progression in the majority of cases, however. No effects of electrical stimulation per se have been demonstrated to date. It must be emphasized that this is a preliminary report with a minimum follow-up of 1 year. Final conclusions await the completion of the study, when all patients have been followed for a minimum of 3 years.
迄今为止，尚无完全令人满意的治疗股骨头坏死的方法。“保守”治疗导致高失败率，手术结果也一直不稳定且令人失望。本文所述的研究旨在评估电刺激联合减压和骨移植的作用。迄今为止，共纳入了82个髋关节，其中42个至少随访1年的已进行评估。无论有无电刺激，大多数接受手术的髋关节均有疼痛缓解和功能改善。然而，使用一种全面的新评估方法进行的仔细影像学评估显示，大多数病例有一定程度的进展。迄今为止，尚未证明电刺激本身有任何效果。必须强调的是，这是一份随访至少1年的初步报告。最终结论有待该研究完成，即所有患者至少随访3年之时。
