Sixty-one randomly selected patients who underwent lumbar fusion surgeries for discogenic low back pain between 1987 and 1994 were retrospectively studied. All patients had failed to respond to preoperative conservative treatments. Forty-two patients received adjunctive therapy with pulsed electromagnetic field (PEMF) stimulation, and 19 patients received no electrical stimulation of any kind. Average follow-up time was 15.6 months postoperatively. Fusion succeeded in 97.6% of the PEMF group and in 52.6% of the unstimulated group (P < .001). The observed agreement between clinical and radiographic outcome was 75%. The use of PEMF stimulation enhances bony bridging in lumbar spinal fusions. Successful fusion underlies a good clinical outcome in patients with discogenic low back pain.
对1987年至1994年间因椎间盘源性下腰痛接受腰椎融合手术的61例随机选择的患者进行了回顾性研究。所有患者术前保守治疗均无效。42例患者接受了脉冲电磁场（PEMF）刺激辅助治疗，19例患者未接受任何形式的电刺激。术后平均随访时间为15.6个月。PEMF组融合成功率为97.6%，未刺激组为52.6%（P<0.001）。临床和影像学结果之间的观察一致性为75%。PEMF刺激的使用可增强腰椎融合术中的骨桥形成。成功的融合是椎间盘源性下腰痛患者良好临床结果的基础。
