摘要
目的探讨后路椎体间打压植骨融合术治疗腰椎滑脱症的临床疗效。方法 2001年1月-2008年7月,采用后路椎体间打压植骨融合术治疗36例腰椎滑脱患者,观察术前、术后及末次随访时的滑脱角、滑脱率、椎间盘高度指数,计算术后滑脱复位率和融合率;采用日本矫形外科学会(Japanese Orthopaedic Association,JOA)评分和Oswestry功能障碍指数(Oswestry disability index,ODI)进行临床疗效评估。结果所有患者获得13～25个月随访,平均随访16.8个月。术后JOA评分和ODI均优于术前,差异有统计学意义(P<0.05);末次随访与术后比较,差异均无统计学意义(P>0.05)。术后的滑脱角、滑脱率和椎间隙高度指数较术前有明显改善,差异有统计学意义(P<0.05);而末次随访与术后比较,差异无统计学意义(P>0.05)。将术后与末次随访的JOA好转率和滑脱复位率分别进行比较,差异无统计学意义(P>0.05)。所有滑脱节段全部融合,无内固定松动、断裂及神经并发症。结论后路椎体间打压植骨融合术是治疗腰椎滑脱症的有效方法之一。
Objective To investigate the clinical effect of bone graft impaction on posterior intervertebral fusion for lumbar spondylolisthesis. Methods From January 2001 to July 2008, 36 patients with lumbar spondylolisthesis were treated by bone graft impaction on posterior lumbar intervertebral fusion （PLIF） with internal fixation. The clinical outcome were evaluated according to Japanese Orthopaedic Association （JOA） scores and Oswestry disability index （ODI）. X-ray evaluation at pre-operation, post-operation and the last follow-up period were performed with slip angle, slip rate and intervertebral disc height, and then the post-operative reduction rate and fusion rate were calculated. Results All patients were followed up from 13 to 25 months （average 16.8 months）. Postoperative JOA scores, ODI, slip angle, slip rate and intervertebral height index improved compared with preoperative data （P 0.05）, while there were no statistical differences of the above parameters as well as JOA improvement rate and slip reduction rate between postoperative and the last follow-up period （P 0.05）. Bony fusions were observed in all cases without neurological complications or internal fixation loosening and breakage. Conclusion Bone graft impaction on posterior intervertebral fusion was one of the effective methods for the treatment of lumbar spondylolisthesis.
