Displacement Pattern of Anterior and Posterior Column Fragments in Both-Column Acetabular Fractures: A 3D Reconstruction-Based Study

Figure 2

Marked points and rotation angles. (a) Nonreduced marked points on AC and PC fragments. (b) Reduced marked points on AC and PC fragments. (c) Top view showing angle α projected by lines between (i)ASIS and ACU before and after AC fragment reduction. (d) Bottom view showing angle β projected by lines between IT and PCL before and after PC fragment reduction (blue points, marked points; green area, AC fragment; purple area, PC fragment; grey area, reduction template; red line, connection between marked points before reduction; dashed red line, parallel to red line; yellow line, connection between marked points after reduction).
