Quadrilateral plate fractures of the acetabulum: Classification, approach, implant therapy and related research progress

Figure 1 The classification map of fracture in the quadrilateral plate and the frequency map of different zones affected by fractures were drawn according to the research of Yang etal[14]. A: Hemipelvis anatomy and quadrilateral plate marked by the red lined area; B: This picture shows the fracture lines of all 238 superimposed fractures; C: This picture illustrates the “corridors” in which nearly three quarters of the major fracture lines occurred; D: Coded map showing the frequency (totals, percentages) of all fractures involved in the different zones indicated in the quadrilateral plate.
