The "safe zone" for infrapectineal plate-screw fixation of quadrilateral plate fractures: An anatomical study and retrospective clinical evaluation.

AbstractExtra-articular screw placement in the true pelvis for fixing quadrilateral plate fractures remains challenging. We aimed to define the “safe zone” on the quadrilateral surface to facilitate safe plate-screw placement.Twenty cadaveric hemipelves were sectioned and assembled to define the pro
