This study was designed to define fracture lines and comminution zones in OTA/AO 23C3 distal radius fractures from axial computed tomography (CT) images that would influence surgical planning, development of new classifications, and possible implant designs.
Thirty-four consecutive OTA/AO 23C3 fractures treated by a single surgeon between January 2014 and December 2014 were analyzed. For each fracture, maps of the fracture lines and zones of comminution were drawn. Each map was digitized and graphically superimposed to create a compilation of fracture lines and zones of comminution. Based on this compilation, major and minor fracture lines were identified and fracture patterns were defined.
All major fracture lines were distributed in the central region of the radius distal articular surface. There is a recurrent fracture pattern with a comminution zone including the scaphoid and lunate fossa; Lister's tubercle; and ulnar, volar, and radial zones.
It is important for the practicing surgeon to understand these four main fragments. Knowledge of this constant pattern should influence the development of new classifications and possible implant designs.
本研究旨在从轴向计算机断层扫描（CT）图像中确定OTA/AO 23C3型桡骨远端骨折的骨折线和粉碎区域，这些信息将影响手术规划、新分类系统的开发以及可能的植入物设计。
对2014年1月至2014年12月间由同一外科医生治疗的34例连续OTA/AO 23C3骨折进行分析。针对每例骨折，绘制骨折线和粉碎区域图。将每张图数字化并进行图形叠加，以创建骨折线和粉碎区域的汇总图。基于此汇总图，确定主要和次要骨折线，并定义骨折模式。
所有主要骨折线均分布在桡骨远端关节面的中央区域。存在一种反复出现的骨折模式，其粉碎区域包括舟状窝和月骨窝、Lister结节以及尺侧、掌侧和桡侧区域。
执业外科医生了解这四个主要骨折块很重要。掌握这种固定模式应能影响新分类系统的开发以及可能的植入物设计。
