目的　探讨新型后路同种异体骨解剖形腰椎融合器治疗腰椎间盘突出症的临床效果。  方法　选取32例腰椎间盘突出症患者为研究对象，均接受新型后路同种异体骨解剖形腰椎融合器治疗。采取视觉模拟评分法（VAS）评估手术前后患者腰痛和腿痛的程度，Oswretry功能障碍指数（ODI）评价患者术后恢复情况。比较手术前后患者腰痛和腿痛的VAS评分、ODI以及平均椎间隙高度变化。   结果　32例患者术后均获得随访，平均随访时间（9.2±3.7）个月，在术后6个月时均获得骨性融合，未发生严重不良反应。术后6个月和末次随访时腰痛和腿痛的VAS评分、ODI评分较术前明显降低，差异均有统计学意义（均P＜0.05）。术后6个月和末次随访时平均椎间隙高度较术前明显增高，差异均有统计学意义（均P＜0.05）。  结论　新型后路同种异体骨解剖形腰椎融合器能够明显改善腰椎间盘突出症患者的临床症状，值得在临床中推广应用。

Objective　To discuss the effecacy of new allograft posterior lumbar fusion cage of anatomical shape in patients with lumbar disc herniation.　Methods　32 patients with lumbar disc herniation were enrolled and all patients were given treatment of new allograft posterior lumbar fusion cage of anatomical shape. Visual analogue scale（VAS） was applied to evaluate the degree of lumbago and leg pain before and after operation and  Oswestry disability index（ODI）was applied to evaluate the postoperative recovery of patients.The VAS of lumbago and leg pain,ODI score and average intervertebral disc height before and after operation of all patients were compared.    Results    all 32 patients were followed up for a mean follow-up period (9.2± 3.7) months. All patients achieved bony fusion and no serious adverse reactions occurred 6 months after the operation. 6 months after the operation and the last follow-up lumbago and leg pain VAS and ODI score was significantly lower than that before operation, and the differences were statistically significant (P<0.05). 6 months after the operation and the last follow-up, the average height of the intervertebral space was significantly higher than that before the operation, and the difference was statistically significant (P<0.05).　Conclusion　The new allograft posterior lumbar fusion cage of anatomical shape can obviously improve the clinical symptoms of patients with lumbar disc prolapse and it is worth popularization and application.
