摘要
目的 探讨侧后方融合联合人工珊瑚椎间融合器治疗腰椎滑脱的临床疗效。方法 2 1例腰椎滑脱 ,其中L4滑脱Ⅰ°5例 ,Ⅱ°3例 ,L5滑脱Ⅰ°7例 ;Ⅱ°3例 ,L4、L5同时椎弓根不连滑脱Ⅰ°3例。平均年龄 4 8.5岁 ,采用后手术入路 ,用Steffee钢板提拉复位 ,侧后方融合联合人工珊瑚椎间融合器椎体间融合稳定脊柱。结果 随访 6～ 4 2个月 ,平均 19.1个月 ,19例术后腰痛消失 ,并感腰部稳定有力 ,18例恢复原工作与生活 ,其中有 5例术后 6个月后恢复体力劳动 ,摄腰椎正侧位片及过屈、过伸位片 ,见椎体间相对运动消失 ,椎间隙较术前平均增高 4mm ,椎间植骨已骨性模糊与上下椎体融合 ,未出现椎体再移位的并发症。结论 采用侧后方融合联合人工珊瑚椎间融合器椎体间融合吸收了前后路两种融合方法的优点 ,使融合率大大提高 ,增强了脊柱的稳定性 ,临床疗效满意。
Objective To explore the clinic effects of lumbar spondylolisthesis treated by posterolaterial fusion with coralline spinal interbody fusion.Methods Twenty one cases of spondylolisthesis (average age was 48.5;L 4 5 cases grade Ⅰ,3 cases grade Ⅱ, L 5 7 cases grade Ⅰ,3 cases grade Ⅱ, both L 4 with L 5 3 cases grade Ⅰ) were treated by posterolateral fusion with coralline spinal interbody plate,spine posterior approach,Steffee pedical pulling screw reduction.Results The average follow up was 19.1 month.19 cases lower back pain disappeared with the felling of back stable, 18 cases returned to original work.5 cases returned to be physical labor.A-P, bi-oblique and bending with extending position X-ray showed that the motion of the vertebra vanished, the gap of the vertebra body increased 4mm, osseous fusion occurred in connected vertebra body and no incidence of vertebra body redislocation.Conclusion There are stable spinal fixation, high incidence fusion rate and excellent clinic results by the combination of posterior and anterior routs fusion method's advantages.
