摘要
目的探讨3D打印技术在胫骨畸形矫形手术中的应用效果。方法选择沈阳军区总医院骨科2014年8月—2015年8月收治的8例胫骨畸形(观察组),通过CT扫描得到的数据进行计算机三维建模、3D打印导板制作和术前预演,行胫骨畸形矫形术。随机选取8例既往未采用手术导板进行截骨矫形的病例为对照组。记录观察组导板制作时间,比较两组手术时间、术中X线"C"型臂机透视次数即术中X线暴露频次。结果观察组导板制作时间(16.5±3.5)h,患者均成功设计制作了手术导板并进行了应用,术区骨面均能与导板准确帖服并引导摆锯截骨成功,矫形后胫骨对位对线均恢复正常,导板在应用过程中未出现变形、断裂。观察组手术时间及术中X线暴露频次均显著少于对照组(P〈0.05)。观察组均获随访,时间为1~16个月,平均4.5个月,截骨端均顺利愈合,无感染,对位对线未出现再次移位。结论 3D打印技术用于骨科矫形领域,具有能够实现术前个体化设计、进行手术预演、缩短手术时间、减少医源性损伤、提高手术效率等优点,临床应用价值较高。
Objective To investigate the effect of 3-dimensional (3D) printing technology in application of tibia deformity orthomorphia. Methods The 3D modeling, guiding plate manufacture and preoperative rehearsal for the CT scanning data of 8 tibial deformity patients (observation group) during August 2014 and August 2015 were performed, and then the 8 patients undertook tibial deformity orthomorphia. A total of 8 patients without 3D printing technology were randomly chosen as the control group. The manufacture time of guiding plate was recorded, and values of operation time and intraoperative exposure frequency of C-arm X-ray in the two groups were compared. Results In the observation group, manufacture time of guiding plate was ( 16.5 :l: 3.5 ) h, and all guiding plates were successfully manufactured and used in the operation; bone surface and plate were suitable in the surgical area, and plates successfully guided the osteot- omy, and the tibia deformity was back to normal line after the orthomorphia without deformation or fracture during the guiding process. The values of operation time and intraoperative exposure frequency of C-arm X-ray in the observation group were significantly lower than those in the control group ( P 〈 0.05 ). The patients in the observation group were fol- lowed up for 1-16 months, and the average time was 4.5 months. Bones healed well without infection or re-malposition. Conclusion The 3D printing technology in application of tibia deformity orthomorphia may achieve preoperative individ- ualized design and preview, shorten the operation time, reduce iatrogenic injury and improve the operative efficiency.
