Comparative analysis of posterior column screw trajectories: pararectus vs. lateral window of the pelvis

Key Points

• To compare the effectiveness of pararectus and lateral window approaches in achieving optimal screw trajectories.
• Comparative analysis of screw trajectories using two different approaches.
• Evaluation of anatomical constraints related to the screw entry points.
• Assessment of alignment with ideal entry angles.
• The lateral window approach aligned more closely with the ideal anatomical corridor.
• The pararectus approach had limitations in achieving optimal angles.
