文题释义:
3D打印技术:术前对患者进行全脊柱CT扫描,把扫描的数据保存至Mimics软件中,通过处理以STL格式导出,对此文件在专用三维打印机下按1∶1比例打印形成病变仿真椎体模型。术前结合相关影像学资料及3D打印模型进行术前虚拟内固定设计及截骨方案的设计,根据之前的设计及测量数据在3D打印模型上对需要固定的节段进行体外模拟内固定和虚拟截骨,并记录所有数据。3D打印技术为临床医师提供了更加直观的、立体的解剖学信息,并通过术前制定个体化的、更加精准的置钉及截骨矫形方案有效的提高手术安全性。
重度僵硬性脊柱侧后凸畸形:常由先天性半椎体患者未及时就诊,发展到后期侧屈X射线片柔韧性小于30%而形成,该类患者往往由于胸腔畸形导致心肺功能障碍,脊柱严重畸形导致不同程度的神经功能损害、截瘫等相应的症状,且病情随年龄持续性的进展,绝大多数患者需手术治疗,但由于该类患者脊柱畸形、解剖不规则、周围组粘连严重,其截骨矫形手术风险极高。因此,对重度僵硬性脊柱侧后凸患者术前制定个体化的、更加精准的置钉及截骨方案设计可以有效降低手术风险。
 
摘要
背景:脊柱严重畸形,解剖不规则,截骨矫形手术风险极高,重度僵硬性脊柱侧后凸患者需要术前制定个体化的、精准的置钉及截骨方案设计以降低手术风险。
目的:探讨3D 打印技术应用在重度僵硬性脊柱侧后凸畸形截骨矫形手术中的疗效。
方法:将2015年1月至2017年6月32例重度僵硬性脊柱侧后凸畸形患者纳入研究,其中16例在3D打印技术辅助下行截骨矫形手术的患者作为试验组,即术前利用3D打印技术重建脊柱模型,在此基础上精确设计合理的截骨方案。其余16例在X射线常规影像学检查指导下行截骨矫形的患者为对照组。记录所有患者围术期相关指标、术后侧后凸畸形矫正效果、椎弓根螺钉置钉准确率及手术并发症发生率等相关指标。
结果与结论:试验组患者的手术时间、术中出血量、术中透视次数、术后引流量、术后并发症发生率、术后侧凸及后凸Cobb角等7个指标均明显低于对照组,置钉准确率及侧凸和后凸矫形率明显高于对照组(P < 0.05)。说明3D打印技术,为重度僵硬性脊柱侧后凸畸形患者截骨矫形术前制定了个体化的、更加精准的置钉及截骨矫形方案,可提高手术安全性,减小手术创伤,临床效果满意。

Abstract:

BACKGROUND: For severe rigid kyphoscoliosis patients, due to severe spinal deformity, and high risk for orthopedic surgery, designing an individualized and precise placement and osteotomy scheme preoperatively is needed to reduce surgery risk.

OBJECTIVE: To evaluate the clinical effect of three-dimensional (3D) printing applied in the orthopedic surgery for severe rigid kyphoscoliosis.
METHODS: Thirty-two patients with severe rigid kyphoscoliosis from January 2015 to June 2017 were included. Sixteen cases underwent 3D-assisted osteotomy (preoperative spinal reconstruction by 3D printing, and designing rational osteotomy scheme, trial group), and other 16 cases received orthopedic surgery under X-ray (control group). The perioperative indexes, postoperative correction effect, accuracy of pedicle screw placement and incidence of complications were recorded.
RESULTS AND CONCLUSION: The operation time, intraoperative blood loss, intraoperative fluoroscopy time, postoperative drainage, postoperative incidence of complications, postoperative scoliosis and kyphosis Cobb angle in the trial group were significantly lower than those in the control group, but the accuracy of pedicle screw placement, scoliosis and kyphosis corrective rate were significantly higher than those in the control group (P < 0.05). To conclude, based on 3D printing, an individualized and precise placement and osteotomy scheme is designed for severe rigid kyphoscoliosis, can improve the operation safety, reduce the trauma, and obtain satisfactory clinical outcomes.
