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 2
The intersection point between the acetabular model and quadrilateral surface observed from the different directions of the Stoppa incision. (a)–(d) The intersection point between “shelled” for 2.95 mm acetabular model and pelvic model, the major area of acetabular model is covered by skin, and the region obtained within the trajectory of the intersection was defined as “dangerous zone.” (e)–(h) The intersection point between “shelled” for 6 mm acetabular model and pelvic model, the major area is included in the surgical sight, and the region outside the trajectory of the intersection was defined as “safe zone”.
