背景：四边形钢板骨折是一组具有挑战性的髋臼骨折。然而，很少有文献描述四边形接骨板的骨折线。本研究旨在探讨四边形接骨板的骨折线及其临床意义。方法回顾性分析髋臼骨折的CT资料。根据X线片、CT及手术记录，对髋臼骨折累及四边形钢板进行Judet-Letournel分型。然后绘制不同类型髋臼骨折在四边形钢板内的骨折图。为了便于裂缝图的表征，我们定义了六条基本裂缝线。结果双柱骨折、T型骨折、前柱后半横断骨折3种髋臼骨折类型的骨折线主要包括上横线和上斜线。后壁骨折和前柱骨折的骨折线虽然以上横线为主，但前者的骨折线位置较低。横形骨折和横形伴后壁骨折的骨折线相似，均以上斜线为主。后柱骨折的骨折线主要包括后垂直线。结论不同类型髋臼骨折的骨折线有一定的规律性。通过骨折标测观察四边形钢板的骨折线，可以帮助骨科医生提高对Judet-Letournel分类的认识，对手术入路的选择和内固定器械的设计有一定的指导意义。
Background Quadrilateral plate fractures are a challenging group of acetabular fractures to manage. However, there is little literature that describes the fracture lines of the quadrilateral plate. The aim of this study was to explore the fracture lines of the quadrilateral plate and relevant clinical significance. Methods CT data from a series of acetabular fractures were retrospectively analyzed. According to the X-ray, CT, and operative records of the patients, Judet-Letournel classification was carried out for acetabular fractures involving quadrilateral plate. Then, the fracture maps of different types of acetabular fractures in the quadrilateral plate were drawn. To facilitate the characterization of fracture maps, we defined six basic fracture lines. Results The fracture lines of the three types of acetabular fractures (double-column fracture, T-type fracture, and anterior column with posterior hemitransverse fracture) mainly included upper transverse lines and upper oblique lines. Although the fracture lines of posterior wall fracture and anterior column fracture were mainly upper transverse lines, the fracture lines of the former were in a low position. The fracture lines of transverse fracture and transverse with posterior wall fracture were similar, both of which were mainly upper oblique lines. The fracture lines of posterior column fractures mainly included posterior vertical lines. Conclusions The fracture lines of different types of acetabular fractures have certain regularity respectively. Observation of the fracture lines of the quadrilateral plate based on fracture mapping can help orthopedic surgeons to enhance the understanding of the Judet-Letournel classification, which may have some significant guidance on the choice of operation approach and the design of internal fixation devices.
