目的　探讨胫骨近端接骨板标准件库建立的方法及临床意义。  方法　采集6套全规格胫骨近端接骨板薄层CT扫描的原始数据，导入Mimics14.0中进行三维重建，以STL格式文件输出至Geomagic对三维模型进行形态学优化。在Mimics中进行体积恢复。利用MedCAD绘制圆柱体状钉道模拟现实锁定钉方向，并完成带钉接骨板形态学标准件库建立。   结果　 (1) 完成186块带钉的接骨板标准件的建立；(2) 经Geomagic外观优化以及Mimics体积恢复，使接骨板三维模型具有较高仿真度。  结论　(1) 基于CT扫描的数据，通过逆向工程软件处理可以实现骨科接骨板的标准件库制备； (2) 接骨板与钉道选择性的组合方式适用于骨折内固定植入手术的数字化设计。

 Objective   To discuss the method of establishing standard parts library of proximal tibia plates and its clinical significance.    Methods    The original image of six sets of full-size proximal tibia plates date were collected which is scanned by thin-section CT, and processed with Mimics 14.0 for the three-dimensional reconstruction, then the models were exported to Geomagic by STL format for morphological optimizing.  The optimized models were exported to Mimics for volume rendering. Cylinder-shaped screw channels was drawn by MedCAD for simulation of channel direction of real-locking screws, and the establishment of standard parts library of plates with screws was then completed.   Results   (1) The establishment of 186 standard parts library of plates with screws was completed. (2) By morphological optimizing in Geomagic and volume rendering in Mimics, the 3D model of plate has high simulation degree. Conclusions   (1) Based on CT scan data ,the standard parts library of orthopedic plate can be achieved by reverse engineering software.  (2) The selective combinations between plate and screw channels were suitable for digital design of fracture internal fixation operation.
