【摘要】 目的评估Cage植骨结合椎弓根螺钉系统内固定术治疗腰椎退行性疾病的疗效。方法采用Cage植骨结合椎弓根螺钉系统内固定术治疗腰椎退行性疾病65例,观察其疗效和并发症。结果所有患者症状明显改善。术后1周按Odom标准评估疗效:优43例;良15例;可7例,优良率达89.2%。所有患者随访3～24个月,末次随访按Odom标准评估疗效:优45例;良16例;可4例,优良率达93.8%。经X线检查,所有患者术后3个月椎体间Cage植骨均达到骨性融合,椎弓根螺钉无断裂,Cage无后移、沉陷,椎间隙高度无明显丢失。近期并发症:神经症状加重4例,脑脊液漏2例;远期并发症:神经症状残留3例。结论椎弓根螺钉技术和Cage植骨融合术的联合应用可以优势互补,降低各自术式的并发症,使脊柱稳定性增加,植骨融合率高,提高了临床疗效,有较大的临床应用价值。更多还原

【Abstract】 Objective To evaluate the effects of Cage bone-implatation conjugating lag screw system internal fixation of vertebral arch pedicle in treatment of lumbar regressive disease.Methods 65 cases of lumbar regressive disease were treated by Cage bone-implatation conjugating lag screw system internal fixation of vertebral arch pedicle,and their effects and complications were observed.Results Symptoms of all cases were obviously ameliorated,with 4 patients neural symptoms aggravation and 2 cerebrospinal fluid leak as immediate complications,and 3 neural symptoms remaining as long-term neural symptoms.Effect evaluation one week after operation according to Odom Criterion were 43 cases excellent,15 fine and 7 acceptable,thus excellent and fine ratio was 89.2%.All cases were followed-up for 3 to 24 months,effect evaluaion of the last follow-up according to Odom Criterion were 45 cases excellent,16 fine and 4 acceptable,thus excellent and fine ratio was 93.8%.After X-ray examination,all cases achieved osseous fusion of Cage bone-implatation between vertebral bodies,with no rupture of lag screw of vertebral arch pedicle,no Cage retrocession or sinking,and with no obvious loss of intervertebral space height.Conclusion Combination of lag screw of vertebral arch pedicle techniques and Cage bone-implatation fusion can work out complementation of each other’s superiorities,reduce complications of each own,magnificantly increase spinal stability,and raise fusion ratio of bone-implatation,thus increase clinical effects and possess higher clinical application value.更多还原
