摘　　要：目的探讨3D打印等技术对胫骨平台SchatzkerⅡ、Ⅲ型骨折关节面复位的应用价值。方法采集胫骨平台SchatzkerⅡ、Ⅲ型骨折CT数据11例进行胫骨3D打印(3D打印组),并采集胫骨平台SchatzkerⅡ、Ⅲ型骨折16例进行传统手术(传统组),对比两组关节面复位后的最大阶梯高度、手术时间,采用独立样本t检验进行统计学分析。结果 3D打印组平均手术时间为(112.3±6.8)min,略低于传统组的(121.7±12.8)min(t=2.223,P=0.036);3D打印组平均最大阶梯高度为(2.8±0.4)mm,少于传统组为(3.1±0.5)mm(t=2.123,P=0.044)。结论 3D打印技术可提高胫骨平台SchatzkerⅡ、Ⅲ型骨折关节面复位效果。Objective To investigate the application value of 3D printing technology on articular surface reduction of Schatzkertype II and IIIfractures of the tibial plateau. Methods 11 patients of tibial plateau fracture （Schatzkertype II and III） were recruited whose CT data were used for three-dimensional （3D） printing to guide the articular surface reductions （3D printinggroup）. As a contrast, 16 patientsof tibial plateau fractures （Schatzkertype II and III） were recruited and were treated by conventional surgical methods （Traditionalgroup）. The maximum step height of articular surface after reduction and operation time were recorded and compared using independent-sample T test. Results The average operation time in the 3D printing group was（112.3±6.8）min, which was significantly shorter than that in the traditional group （121.7± 12.8 min）（t=-2.223, P=0.036）. The maximum step height of articular surface in the 3D printing group were （2.8±0.4）mm, which was significantly less than that in the traditional group （3.1 ±0.5）mm （t=-2.123, P=0.044）. Conclusion The 3D printing technology could improve the articular surface reduction of tibial plateaufractures（Schatzkertype II and III） and decrease the operation time.
