What this Trial Is About

Researchers are comparing two sequences of surgical fixation in patients with vertically unstable Tile C1.2 and C1.3 pelvic ring injuries. The study aims to evaluate clinical and radiological outcomes as well as rates of implant failure. The hypothesis is that starting with the anterior ring fixation will lead to easier reduction, shorter operation times, and better overall radiological and functional results compared to starting with posterior ring fixation. The study involves two procedures. One group will begin with open reduction and internal fixation (ORIF) of the pelvic ring anteriorly using a single 3.5 mm recon plate on the pubic rami and symphysis pubis, followed by posterior fixation with a single sacroiliac screw in the S1 vertebra. The other group will start with posterior ring fixation using the sacroiliac screw first, then perform anterior fixation with the recon plate. Both approaches aim to restore pelvic ring stability and alignment. Participants will be monitored over 12 months to assess radiological and clinical outcomes. Researchers will measure radiological outcome scores and clinical outcome scores at the 12-month mark. The study will track implant failure rates and functional results to determine which fixation sequence provides superior patient outcomes.
