Figure 8: The composite pushes the wire where effective quadrilateral plate buttressing is required, converting its linear supra-acetabular path into a V-shaped line of pull. Lateral traction using a corkscrew below the greater trochanter facilitates reduction (arrow). The wire prevents plate recoil, like checkreins, and improves posterior column fracture fixation against slippage (Farid et al.^[9])
