Digital Anatomy to Improve Screw Insertion Techniques for Plate-Screw Fixation of the Pubic Body

Figure 2

The screw at the line tangential to the obturator. The figure on the left illustrates the simulated screw inserted through the site tangential to the obturator. The safe screw insertion region was the inner region of the screw. The figure on the right illustrates the view of the semitransparent pelvis along the axis of the screw (the red circle is the projection of the screw at the axis). The safe screw insertion region includes the anterior and posterior boundaries that created a V-shape with the tip pointing outward (as indicated by the dotted line).
