摘要
背景:CT重建骨折三维模型不能进行虚拟复位、内固定,不能制定合理的修复方案,无法完全满足临床骨科医师的需要。目的:探讨应用软件在胫骨近端骨折中进行三维重建、复位并设计数字钢板的方法。方法:按照AO分类标准,将9具膝关节标本制作成胫骨近端A1-3、B1-3、C1-3类型骨折模型,进行高速CT薄层扫描,在Mimics中对9种类型的骨折模型进行重建、复位,以Solidworks进行内固定钢板、螺钉的设计,并在骨折复位三维模型上进行虚拟内固定。结果与结论:9种类型骨折均进行了三维重建、复位,完成内固定钢板及螺钉设计以及虚拟内固定,并以A3、B3、C3类型演示。提示应用Mimics及Solidworks可在个人电脑上设计出胫骨近端骨折数字钢板,可为现实修复手术提供参考。
BACKGROUND：In three-dimensional CT reconstruction model,fracture virtual reduction and internal fixation cannot be achieved,and reasonable operation scheme cannot be formulated.It cannot fully meet the needs of clinical orthopedics physicians.OBJECTIVE：To explore the methods to perform three-dimensional reconstruction,reduction on proximal tibial fracture and to design digital plate using software.METHODS：Nine specimens of knee joint were built to be A1-3,B1-3 and C1-3 types of proximal tibial fracture according to the AO standard.All specimens were treated with CT scan.Three-dimensional reconstruction and reduction on nine types of bone fracture models were performed in Mimics.The digital plates and screws were designed in Solidworks.Virtual internal fixation on the reduced three-dimensional models was performed.RESULTS AND CONCLUSION：All bone fracture models received three-dimensional reconstruction and reduction,and the design for internal fixational plates and screws as well as virtual internal fixation were accomplished.A3,B3 and C3 types were presented.These results suggest that the digital plates for proximal tibial fracture could be designed in Mimics and Solidworks with a personal computer.Our experience could be used in the real operation.
