Forty-three patients with chronic pain disorders of different causes were selected for spinal cord stimulation. All underwent implantation of a ribbon electrode through a small laminotomy, under general anesthesia. Thirteen patients (30%) failed to obtain significant pain relief during a period of trial stimulation, and their electrodes were removed. The remainder underwent a definitive implant and were followed for a mean of 13 months (range, 3-33 months). Nineteen of them (63%) continued to experience pain relief. A detailed analysis of this series, as well as a literature review, is presented.
43例因不同病因导致慢性疼痛障碍的患者被选来接受脊髓刺激治疗。所有患者均在全身麻醉下通过小切口椎板切开术植入带状电极。13例患者（30%）在试验刺激期间未能获得明显的疼痛缓解，其电极被移除。其余患者接受了确定性植入，并平均随访13个月（范围3 - 33个月）。其中19例（63%）持续有疼痛缓解。本文对该系列病例进行了详细分析，并进行了文献综述。
