目的 探究骨质疏松性椎体压缩骨折治疗中3D打印技术的应用及其效果。方法 选取我院2016年1月—2018年10月收治的90例行经皮椎体成形术治疗的骨质疏松性椎体压缩骨折患者作为研究对象,随机分为常规组45例和实验组45例。常规组采用MR+常规穿刺方法,通过MR引导,注入骨水泥;实验组采用CT+3D打印技术,在应用CT的基础上,借助制作模型的引导,实施精准定位并实施手术治疗,对两组各项围术期治疗指标(手术时间、射线暴露次数、后凸Cobb角改善)和治疗前后的VAS评分、ODI评分以及骨水泥渗漏情况。结果 在手术时间、射线暴露次数、后凸Cobb角改善等围术期治疗指标方面,实验组均要优于常规组,差异有统计学意义(P<0.05)。在骨水泥渗漏发生率方面,常规组为17.78%(8/45),实验组为4.44%(2/45),实验组低于常规组,差异有统计学意义(P<0.05)。在VAS评分、ODI评分方面,常规组和实验组治疗前、治疗后相比差异均无统计学意义(P>0.05)。结论 骨质疏松性椎体压缩骨折经皮椎体成形术治疗中,配合3D打印技术能够有效提升治疗的有效性,促进患者的健康恢复,值得推广应用。

目的 探讨高黏度骨水泥在治疗骨质疏松性椎体压缩性骨折中的临床疗效分析。方法 随机选取本院2012年1月—2016年1月收治的80例骨质疏松椎体压缩性骨折患者。将患者随机分为对照组和观察组,每组各40例,均采用骨水泥联合经皮椎体后凸成形术治疗,对照组采用低黏度骨水泥,观察组采用高黏度骨水泥。采用视觉模拟量表(VAS)评分比较手术前后患者疼痛情况,Oswestry指数(Oswestry disability index,ODI)评分评估患者腰背部功能。观察并比较两组患者VAS、ODI评分,骨水泥渗漏及相关并发症情况。结果 所有患者均顺利完成手术,术后随访1年以上,期间未发生严重并发症。所有患者VAS评分,ODI评分均明显高于术前。两组均出现骨水泥渗漏及其他并发症,低黏度骨水泥组骨水泥渗漏率为66.7%,明显高于高黏度骨水泥组的33.3%,P<0.05,但均无明显神经功能损伤。结论 高黏度骨水泥在骨质疏松椎体压缩性骨折中的应用能显著改善患者临床疗效,明显降低骨水泥渗漏及并发症的发生率。

Objective To investigate the clinical effect of high viscosity bone cement for treatment of osteoporotic vertebral compression fractures. Methods From Jan. 2012 to Jan. 2016, 80 patients with osteoporosis vertebral fractures were enrolled into this study. They were randomly divided into control group and observation group, with 40 cases in each group. They were all adopted PKP methods for treating, while the observation group got the high viscosity bone cement and the control group got the low one. Clinical outcomes were assessed in terms of back pain visual analogue scale (VAS), Oswestry disability index (ODI) after surgery.The outcomes of back pain VAS score, ODI, venous leakage rate, discoidal leak rate, rate of around vertebral body, rate of contiguous vertebral fracture were compared between two groups. Results All patients were successfully completed surgery. We took postoperative follow-up more than one year, there were severe complications occurred. VAS score, ODI score were significantly higher than that of before operation. Two groups had both bone cement leakage and other complications. Low viscosity bone cement group of bone cement leakage rate was 66.7%, significantly higher than the 33.3% of the high viscosity of bone cement group, P<0.05, but no obvious neurologic injury. Conclusion The high-viscosity bone cement for osteoporotic vertebral fractures provides better clinical outcomes. It may reduce bone cement leak rate and complications.

目的 回顾分析椎体成形术(PVP)对于治疗骨质疏松性新鲜椎体压缩骨折(OVCF)患者的疗效。方法 收集2011年1月—2012年6月新鲜OVCF患者伤后两周内行PVP术治疗共34例(51个椎体)。于术前1天、术后3天、1个月、3个月、6个月、12个月予VAS、ODI评分,并行X线检查以测量病椎前、中、后缘的高度和病椎cobb角。结果 纳入研究的34个病例中,患者术后各时间点随访中VAS和ODI评分均较术前1天明显改善(P<0.05)。术后各时间点随访中行X线检查时,术后各次随访中椎体前缘、中段、病椎cobb角均较术前有较为明显的矫正(P<0.05)。结论 应用PVP治疗新鲜OVCF疗效满意,可快速缓解疼痛、改善生活质量和矫正病椎后凸畸形。

Objective To study the efficiency and safety of percutaneous Vertebroplasty(PVP) for the fresh osteoporotic vertebral compression fractures(OVCF). Methods 34 patients (30 females and 4 males), mean age 75.8 years old(75.79±9.32, range 60 to 93 years old) hospitalized between January 2011 to June 2012 were reviewed retrospectively in this study. Evaluation at follow-up time point(1 day before PVP, 3rd day, 1st, 3rd, 6th, 12th month after PVP) included the pain score with VAS, mobility improvement with ODI and the measurement of anterior, middle and posterior height of the fractured vertebra, and kyphotic angle of the fractured vertebra with X-ray image. Results For the 34 patients by followed up 1 year, the mean VAS score and ODI decreased significantly after PVP at any follow-up time compared with the 1 day before operation. Anterior and middle body height and the focal kyphotic angle at any follow-up time after PVP was improved statistically significant compared with the preoperative value(P<0.05). Conclusion Percutaneous vertebroplasty results in prompt pain relief, rapid rehabilitation and kyposis reduction, it is a safe and effective procedure for treating fresh osteoporotic vertebral compression fractures.
