Blunt End Wire and Lateral Sacral View: A Technical Trick to Precisely Terminate Percutaneous Pelvic Brim Screw Fixation in the Posterior Ilium.

Abstract

Percutaneous screw fixation in the treatment of a variety of pelvic fractures may involve placement of a pelvic brim or "LC-2" screw. The technique requires the use of the combined obturator oblique inlet view to define the medial and lateral cortical borders of the corridor and an iliac oblique view to define the cranial aspect of the sciatic notch. No technique has been reported on how to safely avoid placement of such percutaneous fixation beyond the posterior cortex of the ilium. A simple technique using the blunt end of a guidewire and a true lateral of the posterior ilium is reported.
