| 摘 要： | 
目的探讨3D打印技术结合虚拟手术设计为髋臼骨折患者制定个性化导航模块的可行性方案。方法采集20例临床髋臼骨折薄层CT扫描数据，导入Mimic17.0中进行三维重建、虚拟骨折复位、内固定植入、导航模块设计。将复位骨折模型和导航模块3D打印出实物模型进行手术模拟并进行X线照片和CT扫描，比较虚拟手术与模拟手术导航螺钉长度、方向，是否进入髋关节。结果所有病例均按照虚拟手术设计完成模拟手术，3D模拟手术螺钉进针位置和螺钉长度、方向与数字化设计高度一致，通过导航模块辅助植入螺钉107颗，螺钉长度进行配对t检验P=0.476（P < 0.05），螺钉方向偏差1°~5°的7颗，偏差大于5°的0颗，没有螺钉进入关节腔。结论3D打印结合虚拟手术设计能为髋臼骨折患者制定个性化导航模块，能有效提高内固定植入精确性。3D打印技术结合虚拟手术技术能为髋臼骨折患者制定个性化手术方案。

| Abstract: |
ObjectiveTo evaluate the feasibility of the patient-specific intraoperative guides for acetabular fractures through the technolgy of 3D printing and digit design.MethodsTwenty patients with acetabular fractures were collected in this study. Data of CT scanning were imported into Mimics17.0 software for 3D anatomical modeling, virtual fracture reduction, virtual surgery and the design of intraoperative guides. 3D printing technique was used to print the reducted model and the patient-specific intraoperative guides for simulating the surgery. Finally, the real operation was compared with virtual preoperative design in terms of the direction and the length of screws.ResultsA total of 107 screws were implanted with intraoperative guides. The direction of screws were in high accordance with the digital design. The length of screws are compared with Paired-samples T Test and P=0.476. There are 7 screws direction deviation in 1-5°, no screw implangted in the joint.ConclusionThe 3D printing technology combine with virtual surgery for acetabular fractures is feasible and effective to improve patient-specific intraoperative guides planning by surgery simulation in virtual and reality. Secondly, the combination of Three-Dimensional Printing and virtual surgical procedure can provide a patient-specific preoperative planning in acetabular fractures |
