Results of surgical treatment in 50 failed back surgery patients were retrospectively reviewed to determine what factors influenced surgical outcome. Before surgery, all patients had disabling pain and limited function. Overall significant improvement in pain and function was obtained in 66% of the patients. Thirteen of 16 patients (81%) who had successful fusion of pseudarthrosis had a satisfactory outcome, whereas only 3 of 13 patients (23%) who had failed pseudarthrosis repair had a satisfactory outcome. Successful pseudarthrosis repair is the key to a high clinical success rate in revision surgery for failed back surgery syndrome. Pseudarthrosis repair by conventional posterolateral fusion with postoperative lumbosacral corset immobilization showed a high failure rate. The success rate of reoperation on failed back surgery syndrome patients is low.
对50例腰椎手术失败患者的手术治疗结果进行回顾性分析，以确定哪些因素会影响手术效果。术前，所有患者均有致残性疼痛且功能受限。66%的患者在疼痛和功能方面总体有显著改善。16例假关节成功融合的患者中有13例（81%）预后良好，而13例假关节修复失败的患者中只有3例（23%）预后良好。成功修复假关节是翻修手术治疗腰椎手术失败综合征获得高临床成功率的关键。采用传统后外侧融合术并术后使用腰骶部束腹带固定进行假关节修复，失败率较高。腰椎手术失败综合征患者再次手术的成功率较低。
