摘要
目的探讨经腰椎后路360°融合术治疗腰椎不稳的效果。方法采用经腰椎后方入路,对椎体间、小关节突横突后侧植骨融合,椎板棘突植骨重建后柱,实现以椎管为中心的360°椎间融合术,治疗各种原因引起的腰椎不稳56例,随访时间2～5年。结果腰腿痛麻症状消失者50例,症状大部分缓解者4例,症状未缓解者2例。37例腰椎滑脱者有31例复位满意,6例残留Ⅰ度滑脱,37例均恢复椎间隙高度,没有植入物移位或下沉情况。56例病人中有55例获得骨性融合,1例出现椎弓根螺钉断裂、假关节形成,经翻修手术后融合成功。结论经后路360°融合术治疗症状性腰椎不稳疗效好、椎间融合率高。
Objective To assess the efficacy of posterior 360° lumbar fusion for lumbar instability. Methods Through posterior lumbar approach, interbody fusion was done by interbody and posterial lamina-spinous process bone-grafting to treat 56 patients with lumbar instability caused by various reasons and followed for 2--5 years. Results The symptoms of lum- bago, leg pain and numbness disappeared in 50 patients, substantial partial remission in four, and not improved in two. Of 56 pa tients treated, bony fusion was noted in 55, one showed pseudarthrosis and broken pedicle screws, who was cured after re-surgery. Conclusion Posterior approach 360° lumbar interbody fusion is effective for symptomatic lumbar instability with a high interbody fusion rate.
