3D 打印技术在复杂胫骨平台骨折治疗中的临床应用

摘要

目的：探讨3D 打印技术在复杂胫骨平台骨折手术治疗中的可行性和临床应用价值。方法对临床上复杂胫骨平台骨折的患者进行螺旋 CT 扫描，将其 DICOM 数据输入计算机中，采用 Mimics 软件数据处理，应用3D 打印技术打印骨折三维模型。按胫骨平台三柱分型重新进行分型，在3D 打印模型上确定手术入路及手术体位，并进行骨折的准确复位及钢板放置的选择等模拟手术。结果重建的胫骨平台骨折三维模型能准确反映出骨折移位的方向和程度，可准确的进行骨折的三柱分型，可初步实现胫骨平台骨折的术前手术设计。结论3D 打印技术应用于复杂胫骨平台骨折的治疗，临床可行性良好，可作为术前准备的常规项目。%Objective To explore the feasibility and clinical value of three-dimension(3D)printing technology in the treatment of complex tibial plateau fracture. Methods Spiral CT scan was performed in patients with complex tibial plateau fracture. DICOM data were imported into Mimics software. The 3D printing technology was used to print the fracture models. The reclassilifcation was performed on the basis of three-dimensional measurements. According to 3D printing models,we de-cided the surgical approach and position,the reducted of fractures and choose the internal fixation. Results Reconstructed 3D printing models of complex tibial plateau fracture could show the characteristics of fracture accurately,help doctors to reclassify the fracture from the three-column,and decide preoperative plan in the tibial plateau fracture. Conclusion The 3D printing technology is helpful for the treatment of complex tibial plateau fracture,which should be a conventional step in the manage-ment of complex tibial plateau fracture.
