Early detection and appropriate management are of utmost importance. This retrospective study, utilizing data from the German Pelvis Registry (GPR), evaluates bleeding complications (BC), the effect of pelvic circumferential compression devices (PCCDs) on transfusion requirements and outcomes, and the role of acute measures such as pelvic clamps, external fixators, pelvic tamponade and embolization.</p><p><strong>Methods: </strong>Inclusion criteria: Adults (≥ 17 and ≤ 64 years) with partially unstable or unstable PRI (Tile type B and C), with (BC) or without bleeding complications (nBC) recorded in the GPR between July 2018 and February 2023. BC was defined as significant pelvis-related bleeding requiring blood transfusions and/or resulting in systolic blood pressure < 100 mmHg.
