Classification method and surgical planning method for distal radius fracture based on CT three-dimensional reconstruction

By using CT three-dimensional reconstruction technology, the articular surface of distal radius fractures is divided into four independent regions based on clear anatomical landmarks and geometric rules. This solves the problems of poor consistency and low efficiency of existing classification methods, achieves seamless integration with internal fixation surgery planning, and improves the accuracy of fracture treatment.

Abstract

本发明提供基于CT三维重建的桡骨远端骨折分型方法及手术规划方法，包括步骤：S1.获取患者桡骨远端CT断层图像序列，重建得到包含舟骨窝、月骨窝及尺骨乙状切迹完整解剖结构的三维立体模型；S2.在三维模型上定位桡骨茎突最高点和尺骨乙状切迹中点，以两点为端点在对应三维坐标系中创建虚拟基准轴线；S3.分别定位舟骨窝、月骨窝最低点，过两点各作一条平行于基准轴线的第一虚拟分割线、第二虚拟分割线，再作一条垂直于基准轴线且穿过两窝解剖交界区域的垂直辅助线，将桡骨远端关节面关键承重区划分为四个独立解剖区域；S4.根据骨折线空间走向与骨折块移位范围，判断骨折累及的解剖区域，完成桡骨远端骨折分型。本发明提升了诊疗精准性与效率。
