两种椎间融合器联合椎弓根螺钉治疗腰椎滑脱症的疗效比较

The Comparison of the Rapeutic Efficacy of the Treatment of Lumbar Spondylolisthesis by Two Kinds of Cage Combined with Pedicle Screw System

目的比较两种椎间融合器联合椎弓根螺钉内固定治疗腰椎滑脱症的临床疗效。方法回顾性分析手术治疗腰椎滑脱症65例。术后应用复位指数、融合率、Oswestry功能障碍指数(ODI)、日本矫形外科学会(JOA)的下腰痛评定标准,判断两组患者临床疗效,应用Student-Newman-Keuls检验分析。结果术后随访24~36个月,平均30个月。A,B两组患者复位指数术前术后均有显著性差异(P<0.05),A,B两组融合率无显著性差异,A,B两组术前和术后ODI、JOA评分有显著性差异(P<0.05)。结论两种术式均取得了良好的手术效果,两种术式在临床疗效方面无显著性差异,两种融合器在临床实践中均值得推广应用。

Objective To compare the clinical efficacy between carbon fiber interbody and polyetheretherketone cage combined with pedicle screw fixation for the treatment of lumbar spondylolisthesis. Methods 65 cases with lumbar spondylolisthesis were treated with carbon fiber interbody or polyetheretherketone cage combined pedicle screw system. The reset index, the rate of fusion, Oswestry dysfunction index（ODI）, Japanese Orthopaedics Association（JOA）score system was used to evaluate the clinical efficacy, Student-Newman-Keuls test was applicated. Results 65 cases were followed up for 24-36 months after operation, an average of 30 months. There was statistical significance of the reset index between preoperation and postoperation for the two groups of patients（P 〈0.05）, and no statistical significance of the rate of fusion between A group and B group. The mean scores of JOA and ODI showed statistical significance between preoperation and postoperation（P 〈0.05）. Conclusion Two kinds of surgical operation were achieved good effect, no significant difference between the two kinds of operation in clinical curative effect, the two kinds of interbody is worthy of popularization and application in clinic.
