However, five cases (19.2%) of the posterior-only fixation group showed secondary displacement with a mean of 5.9\u00a0mm. Four cases of them had tetra-ramic injuries. There is a high tendency for secondary displacement at 14.5\u00a0mm or more preoperative displacement of the rami. Patients with secondary displacement showed comparable functional outcome scores to patients without secondary displacement. Posterior-only fixation showed shorter operative time, lesser radiological exposure, blood loss and iatrogenic nerve injury than anterior\u2013posterior fixation.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>EUA is a reliable method to determine pelvic instability and management plan for LC fractures with unilateral anterior ring injury.
