Gardner and Routt describe the transiliac–transsacral screw technique, in which 7.3-mm cannulated screws traverse the entire upper sacrum and exit the contralateral iliac cortex, offering an alternative to standard iliosacral fixation when deforming forces or patient factors make standard fixation inadequate. The paper presents the technique with a 56-patient clinical series.
When standard iliosacral fixation is likely to be insufficient — osteoporotic bone, bilateral posterior injuries, spinopelvic dissociation, marked comminution, obesity, or anticipated noncompliance.
Transiliac–transsacral screws offer cortical anchorage in the contralateral ilium and greater thread engagement across the full sacral width; preoperative CT measurement of the transsacral safe zone is mandatory before committing to this trajectory.
