摘要
[目的]对比Coflex系统植入与全椎板减压植骨融合、椎弓根螺钉内固定术治疗退行性腰椎管狭窄症的短期疗效。[方法]抽取连续的30例住院治疗的退行性腰椎管狭窄症患者,随机分为两组,每组15例,分别施行Coflex系统植入和全椎板减压植骨融合椎弓根螺钉内固定术,观察比较两组的手术时间、出血量、术后住院时间、术前和术后6个月JOA评分,术后改善率及并发症情况。[结果]与传统减压融合术相比,Coflex组术后6个月JOA评分及术后改善率无明显差异,而手术时间、出血量及住院时间显著降低。随访期间Coflex组无1例发生术后并发症。[结论]Coflex植入系统是一种安全、有效、微创的治疗退行性腰椎管狭窄症的新术式,具有较好的临床应用前景。
[Objective]To compare the short term outcome in treatment of degenerative lumbar stenosis with Coflex implant versus laminectomy and posterior interbody fusion along with pedicle screw system. [Methods]Thirty patients with degenerative lumbar stenosis were randomly divided into two groups.Fifteen patients in the control group were treated with laminectomy and posterior interbody fusion along with pedicle screw system. The other 15 patients in the experiment group were treated with Coflex implant. The parameters for assessment included operation time,intraoperative blood loss,hospital stay,pre- and postoperative JOA score,improvement rate and complication rate.[Results]Compared to the control,significant reduction was found in terms of operation time,intraoperative blood loss,and hospital stay in the experiment group.No significant difference was found regard to the improvement rate and postoperative JOA score. In addition ,there was no complication in the Coflex group during the follow-up.[Conclusion]Coflex implant is an effective,save and minimally invasive surgical method for the treatment of degenerative lumbar stenosis.
