| ［摘要］ 目的 探讨3D打印技术在复杂胫骨平台骨折手术中的临床应用价值。方法 对该科2例SchatzkerⅥ型的复杂胫骨平台骨折患者术前进行螺旋CT扫描，数据采用Mimics软件作三维重建处理。应用3D打印技术打印病例的胫骨平台骨折模型，根据模型选择合适的复位方法及内固定物，于内固定前模拟手术过程。从手术入路、钢板种类、放置位置、长度、螺钉数量及长度方面与模拟手术进行对比，同时对实际手术时间进行记录。结果 2例完全采用了计划固定方法，术中选取的固定钢板、螺钉数与螺钉长度均与模拟手术高度吻合。术后复查X线显示骨折复位满意，关节面达到解剖复位，内固定物位置良好，没有螺钉穿入关节腔。结论 3D打印技术应用于复杂胫骨平台骨折的治疗，可多角度、多方向显示胫骨平台骨折部位的形态学外观特点；能在术前明确钢板植入位置、螺钉方向和长度并完成钢板预塑形，有助于术者对复杂胫骨平台骨折的理解和术前计划的制定，有效缩短手术时间，提高手术效率。 |

| ［Abstract］ Objective To evaluate the application value of three-dimensional(3D) printing technique in the surgical treatment of complex tibial plateau fracture.Methods Two cases with complex tibial plateau fractures of type SchatzkerⅥ were enrolled in this study. On preoperative spiral CT scanning, the data of lamellar CT scanning were imported into Mimics 14.0 software for 3D anatomical modeling, and then internal fixations were simulated based on all the printer models. The simulated operation was compared with the real operation in the surgical approach, the type of steel plate, the placement of steel plate, the length and number of screw.Results Two cases fully adopted the planned fixed methods. The number of fixed steel plate, the number and length of screw in the real operation were accordance with those in the simulated operation. X-ray showed that the fractures were reached anatomical reattachment with internal fixation in the good position and fractures were reset satisfactorily.Conclusion 3D printing technology can help understanding complex fractures of tibial plateau and developing the preoperative planning, shortening the operation time and improving the operation efficiency in the treatment of complex tibial plateau fractures. |
