Radiographic parameters and feasibility analysis of dual sacral-2 alar-iliac screw fixation using three-dimensional digital technology
Using a radius of 4 mm (minimum diameter of S2AI screw) as a standard, it is feasible to place two S2AI screws on the same side for the Chinese adult. Screw placement can be achieved by trisecting the lateral process of S1-S2, with one screw inserted in the bottom third and the other in the upper third. Furthermore, preoperative three-dimensional digital technology simulation analysis can effectively simulate the dual S2AI screws trajectories on the same side, and they can provide accurate data for clinical applications.
