Measurement of the “Safe Zone” and the “Dangerous Zone” for the Screw Placement on the Quadrilateral Surface in the Treatment of Pelvic and Acetabular Fractures with Stoppa Approach by Computational 3D Technology
Figure 5
The region within the red rectangle is dangerous for screw placement with the Stoppa approach, but it becomes safe if the direction is proximal to Stoppa approach. (a) Proximal view from the Stoppa incision; (b) opposite view from the Stoppa incision; (c) the view direction proximal to Stoppa approach.
