Schematic representation of bilateral posterior transosseous S1 pedicle access trajectories toward the superior hypogastric plexus region

Caption

The proposed right and left transosseous pathways (black arrows) illustrate a convergent trajectory through the S1 pedicles toward the anterior sacral cortex and presacral space, where the superior hypogastric plexus is anatomically located (yellow area). The proximity of critical vascular structures, including the iliac vessels (red and blue), highlights the potential risk associated with anterior cortical transgression. This schematic underscores the conceptual advantage of a fixed osseous corridor while simultaneously illustrating the unresolved safety considerations related to anterior sacral anatomy. SHP, superior hypogastric plexus.
