摘要
目的探讨3D打印个体化导航模板辅助腰椎椎弓根螺钉置入术治疗腰椎滑脱的疗效。方法选取我院2013年3月至2015年3月期间收治的腰椎滑脱患者60例,依据随机数字表法随机分为观察组30例与对照组30例。对照组术前应用传统三维CT重建图像制定手术方案,观察组术前应用3D打印技术制定手术方案。比较两组患者手术时间和出血量,术前、术后3个月、术后6个月、术后12个月脊髓功能日本骨科协会(Japanese orthopaedic association,JOA)评分、视觉模拟评分(visual analogue scale,VAS)变化及术后并发症发生情况。结果观察组手术时间短于对照组,且出血量少于对照组(P<0.05);两组JOA评分术后3个月、术后6个月、术后12个月增加(P<0.05);观察组JOA评分术后3个月、术后6个月、术后12个月高于对照组(P<0.05);两组VAS评分术后3个月、术后6个月、术后12个月降低(P<0.05);观察组VAS评分术后3个月、术后6个月、术后12个月低于对照组(P<0.05);观察组术后并发症发生率低于对照组,但差异无统计学意义(P>0.05)。结论 3D打印个体化导航模板辅助腰椎椎弓根螺钉置入术治疗腰椎滑脱疗效显著,值得研究。
Objective To explore the effect of 3D printing individualized navigation template in the treatment of lumbar spondylolisthesis with lumbar vertebral pedicle screw placement.Methods 60 cases of lumbar spondylolisthesis admitted to our hospital from March 2013 to March 2015 were randomly divided into the observation group （30 cases） and the control group （30 cases）.The control group used the traditional three-dimensional CT reconstruction image be- fore operation to make the operation plan,and the observation group used the 3D printing technique to make the opera- tion plan before operation.Comparison of two groups of patients with operation time and blood loss, preoperative and postoperative 3 months,6 months after surgery,postoperative spinal cord function 12 months Japan Association （Japa- nese Orthopaedic Association, Department of orthopedics, J OA） score, visual analogue scale （visual analogue scale, VAS） of complications and postoperative changes.Results The operation time of the observation group was shorter than the control group,and the bleeding was less than the control group （P〈0.05）;add 12 months JOA score of two groups after 3 months and 6 months after surgery,postoperative （P〈0.05） ;the JOA score of the observation group af ter 3 months and 6 months after surgery,surgery after 12 months was higher than the control group （P〈0.05）;reduced 12 months VAS score of two groups after 3 months and 6 months after surgery, postoperative （P〈0.05）;the VAS score of the observation group after 3 months and 6 months after surgery, 12 months after the operation was lower than that of control group （P〈0.05） ;the incidence of complications was lower than control group patients in the ob- servation group,but the difference was not statistically significant （P〉0.05）.Conclusion 3D printing individualized navigation template assisted lumbar pediele screw placement in the treatment of lumbar spondylolisthesis is significant and worthy of study.
