摘要
目的对比研究椎弓根螺钉系统固定中后外侧融合与后路椎间融合治疗老年腰椎滑脱的疗效。方法126例采取椎管减压植骨融合附加椎弓根内固定的手术方法,37例获得随访,其中16例采用后外侧融合,其余采用椎间融合,比较两种植骨方式手术时间、出血量和术后骨性融合率。结果椎间融合手术时间较后外侧融合增加24min,出血量增加约231mL,二者差异有统计学意义(P<0.05);骨融合率分别为87.5%、93.5%,二者差异无统计学意义(P>0.05)。结论后外侧融合与椎间融合手术治疗老年腰椎滑脱的融合率相似,但后外侧融合可缩短手术时间、减小手术创伤,有利于老年患者耐受手术和加快术后康复。
Objectlve To evaluate the outcome of posterolateral fusion with pedicle screw system and posterior lumbar interbody fusion with pedicle screw system for treatment of old patients with spondylolisthesis. Methods 126 patients with spondylolisthesis were undergone decompression and bone graft fusion with a pedicle screw system. 37 patients were followed up. 16 patients were undergone posterolateral fusion, 21 patients were undergone posterior lumbar interbody fusion. The operation time, blood loss volume and bony fusion rate were compared between two groups. Results The operation time of posterior lumbar interbody fusion was 24 minutes more than that of posterolateral fusion, and blood loss volume was 231 more. There is significant difference between two groups（P〈0.05）. The fusion rate was 87.5 % with posterolateral fusion and 93.5% with posterior lumbar interbody fusion. There is no significant difference between two groups（P〉0.05）. Conclusion Although the fusion rate of posterolateral fusion is similar with posterior lumbar interbody fusion, with the posterolateral fusion the operation time is shortened and the injury to patient is reduced, so it is benefit for patients to overcome operation and speed up postoperative rehabilitation.
