【摘要】：目的探讨微辐射技术在导航引导经皮椎体成形术(PVP)中减少辐射的效果。方法通过3项手术器械(体表椎体定位器、经皮导航动态参考架、导航专用穿刺针)的研制和2项引进技术(双铅板和骨水泥液压输送)的应用,与现有导航引导下PVP进行对比。因单椎体骨折行PVP患者80例,随机分为改良组和对照组各40例,改良组使用通过3项手术器械研制和2项引进技术的应用得以改良的微辐射技术,对照组使用目前国内医院常用的导航引导下PVP,术后随访12个月,观察分析手术前后VAS评分、平均手术时间和术者暴露剂量。结果 80例椎体成功注射骨水泥,无严重并发症,术后随访时间8~24个月,平均16个月,所有患者手术前后VAS评分均有显著差异,两组间差异不明显。改良组平均手术时间少于对照组,术者暴露剂量明显低于对照组(P0.01)。结论采用微辐射技术的导航引导下PVP,能有效缩短手术时间,特别是能明显减少术者暴露剂量,大大提高了需反复承受医疗辐射术者的人身安全。
[Abstract]:Objective to evaluate the effect of microradiation in navigation guided percutaneous vertebroplasty (PVP). Methods through the development of three kinds of surgical instruments (body surface vertebrae positioner, percutaneous navigation dynamic reference frame, navigation special puncture needle) and the application of two imported techniques (double lead plate and bone cement hydraulic transportation). Compared with PVP under existing navigation guidance. Eighty patients with PVP due to single vertebral body fracture were randomly divided into two groups: the modified group (n = 40) and the control group (n = 40). Patients in control group were followed up for 12 months under the guidance of navigation, and VAS scores, mean operating time and exposure dose were observed and analyzed before and after operation. Results 80 cases of vertebral body were injected with bone cement successfully without serious complications. The follow-up time was 8 ~ 24 months (mean 16 months). There was significant difference in VAS score between the two groups before and after operation, and there was no significant difference between the two groups. The average operation time of the modified group was less than that of the control group, and the exposure dose of the operation group was significantly lower than that of the control group (P0.01). Conclusion under the guidance of microradiation, PVP can effectively shorten the operation time, especially reduce the exposure dose of the operator, and greatly improve the safety of the patients who need repeated medical radiation.
