目的 探讨Solidworks软件在胫骨平台骨折术前评估和虚拟手术中的价值.方法 将胫骨平台骨折患者的Dicom格式CT扫描图像数据导入MIMICS14.01软件,重建膝关节和胫骨平台骨折三维模型,拟合曲面后将Iges文件导入Solidworks2013软件生成CAD模型.对骨折情况进行立体多角度观察,对胫骨平台骨折平台塌陷程度、膝关节半脱位程度等进行三维数据测量及植骨量测算.在膝关节CAD模型上规划手术入路,充分暴露骨折端,模拟克氏针撬拨等方式行骨折复位,通过开窗打压植骨恢复关节面平整性,将复位成功的骨折模型用钢板螺钉系统进行内固定.结果 重建的胫骨平台骨折三维可视化CAD模型可进行立体多角度观察和测量,初步实现了对胫骨平台骨折的术前评估,完成了以规划手术入路、暴露骨折端、模拟骨折复位、开窗植骨、内固定为主要步骤的虚拟手术.结论应用Solidworks软件能够重建胫骨平台骨折CAD模型,对骨折情况进行便捷和精确的术前评估,完成虚拟手术操作,将为临床工作提供可靠依据.%Objective To investigate the value of Solidworks software in preoperative evaluation and virtual surgery of tibial plateau fractures.Methods The Dicom format CT image data of tibial plateau fracture patients were inputted into MIMICS14.01 software,and 3D reconstruction of the knee and tibial plateau fractures were imputed into Solid-works 2013 software after fitting surface after the Iges format files.The fractures'CAD models were shown from differ-ent perspectives and measured accurately.We designed operative approaches,exposed fracture area,performed virtual reduction and internal fixation with computer.Results The CAD models of tibial plateau fractures showed us the de-tails of fracture from different perspectives include the degree of comminution and displacement.We finished the preop-erative evaluation of tibial plateau fractures,performed virtual surgery include designing surgical approaches,exposing the fracture area,simulate fracture reduction,fenestration and bone grafting and internal fixation.Conclusion Solid-works software can reconstruct the CAD models of tibial plateau fractures,achieve the fracture assessment and preoper-ative virtual surgery.Solidworks software will provide a reliable method and basis for clinical work.
