腰椎后外侧融合术和腰椎后路椎体间融合术治疗腰椎间盘突出症的比较研究

目的比较腰椎后外侧融合术和腰椎后路椎体间融合术治疗腰椎间盘突出症的临床效果。方法选择河北大学附属医院2009年9月～2011年8月收治的腰椎间盘突出症患者106例作为研究对象，按照不同手术方案分为两组，采用腰椎后外侧融合术治疗的52例作为A组，采用腰椎后路椎体间融合术治疗的54例作为B组．比较两种手术方案的治疗情况。结果A组的总有效率为84．6％，明显低于B组的98．1％，组间差异有统计学意义（P〈0．05）：两组平均手术时间、术中出血量以及平均住院时间比较，差异均无统计学意义（P〉0．05）；B组的椎间高度、节段角度恢复情况均明显优于A组，组间差异均有统计学意义（P〈0．05）；A组的并发症发生率为3．8％，B组为3．7％，组间差异无统计学意义（P〉0．05）。结论腰椎后路椎体间融合术治疗腰椎间盘突出症能够获得更佳的临床效果且安全性可靠，能更有效地改善椎体间融合情况，有利于患者的康复。

Comparative study of posterolateral lumbar fusion and posterior lumbar interbody fusion in the treatment of lumbar disc herniation

Objective To compare the clinical efficacy of posterolateral lumbar fusion and posterior lumbar interbody fusion in the treatment of lumbar disc herniation. Methods From September 2009 to August 2011 in our hospital, 106 cases of lumbar disc herniation were treated divided into two groups according to different surgical plan, 52 cases with posterolateral lumbar fusion as group A, and 54 cases with posterior lumbar interbody fusion as group B, the therapeu- tic condition of two different surgical plan were compared. Results The total effective rate of group A was 84.6%, sig- nificantly lower than 98.1% of group B, the difference was statistically significant between two groups （P 〈 0.05）; the average operative time, blood loss and the average length of stay of two groups were compared, there were no statisti- cally significant difference between two groups （P 〉 0.05）; the recovery of intervertebral height and segmental angle of group B was significantly better than group A, the differences were statistically significant （P 〈 0.05）; the differences were statistically significant between two groups; the complication rate of group A was 3.8%, and the group B was 3.7%, there was no statistically significant difference between two groups （P 〉 0.05）. Conclusion Posterior lumbar in- terbody fusion in the treatment of lumbar disc herniation has better clinical effects and reliable security, and more ef- fectively improve the interbody fusion, being conducive to the rehabilitation of patients.
