In 24 cases, the device was used as emergency stabilization, and in 4 cases as an adjunct or intraoperative reduction tool. Pelvic reduction was assessed using pre- and postoperative CT scans. Anterior and posterior diastasis, as well as vertical displacement, were measured. Radiological outcomes were classified using Matta\/Tornetta criteria. Subgroup analyses were performed according to fracture type (A\/B vs C), presence of sacral or pubic fractures, and bilateral involvement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Posterior diastasis decreased from 2.54 \u00b1 2.09 cm preoperatively to 0.30 \u00b1 0.67 cm postoperatively. Anterior diastasis improved from 2.54 \u00b1 3.00 cm to 0.35 \u00b1 0.51 cm. Vertical displacement was reduced from 1.18 \u00b1 0.95 cm to 0.36 \u00b1 0.52 cm. Excellent or good radiological outcomes were achieved in 89.3% of cases. No significant differences were observed between fracture types or injury patterns. The complication rate was low, with pin site infection in 7.1% of cases (n = 2) and no observed re-displacement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The pretensioned pelvic external fixator is a simple and effective technique for achieving immediate radiological reduction in unstable pelvic injuries.
