3D打印与虚拟现实设计在胫骨平台骨折的应用

Three dimensional printing and virtual reality assisted open reduction and internal fixation of tibial plateau fractures

[目的]探讨应用3D打印联合Solidworks虚拟手术设计治疗胫骨平台骨折中的临床效果。[方法]采集膝关节CT扫描数据,建立3D 1∶1打印骨折模型,模拟骨折复位内固定。此外,数据经Solidworks 2017软件处理,建立虚拟现实模型,制定个体化的手术方案。[结果]2017年1月~2017年12月21例胫骨平台骨折患者分为两组,11例采用3D打印联合虚拟现实设计手术(辅助组),10例常规手术(常规组)。辅助组在手术时间、钢板一次性放置率、Rasmussen优良率及HSS临床功能评分方面优于常规组(P<0.05)。[结论]应用3D打印联合Solidworks虚拟手术设计可提高胫骨平台骨折治疗的临床效果。

[Objective]To introduce the technique and primary clinical outcomes of 3D printing and virtual reality assisted open reduction and internal fixation(ORIF)of tibial plateau fractures.[Methods]The CT scanning data was used to create a 3D real model of the knee in ratio of 1:1 for simulation of ORIF.In addition,the data were also processed by Solidworks 2017 software to form a virtual reality model for preoperative design.[Results]A total of 21 patents underwent ORIF for tibial plateau fractures.Of them,11 patients had the 3D printing and virtual reality assisted ORIF(the assisted group),while the remaining 10 patients had ORIF without assistance(the conventional group).The assisted group proved significantly superior to the conventional group regarding to operation time,accuracy of plate placement on the first time,excellent and good rate in Rasmussen criteria and HSS score at the latest follow up(P<0.05).[Conclusions]The 3D printing and virtual reality assisted ORIF does improve clinical outcomes of tibial plateau fractures.
