Secure Screw Placement in Management of Acetabular Fractures Using the Suprapectineal Quadrilateral Buttress Plate

Figure 3

Angulation of screws of the quadrilateral buttress plate. 3D reconstruction of a treated acetabular fracture. (a) In frontal view, the angle between the quadrilateral buttress plate (dotted white line) and the screw defines the craniocaudal angle γ. (b) In inlet view the angle between the quadrilateral buttress plate and the screw defines the anteroposterior angle δ.
