The analysis carried out to assess the degree of agreement between FAST-PLUS and CT showed 5/67 patients (7.5%) with a critical pubic SW (> 2.5 cm transverse diameter) suggestive of unstable OB pelvic injury and 62/67 (92,5%) without any signs of SW at FAST-PLUS. At CT, findings of unstable OB pelvic fracture were confirmed in all patients with positive results at FAST-PLUS. Similarly, all patients with negative results for critical pubic SW (< 2.5 cm in transverse diameter) at FAST-PLUS were found to be negative at CT exam. The level of correlation between the two methods was high (Kappa value = 1) CONCLUSION: The FAST-PLUS protocol shows a high correlation with CT exam, which is the gold standard for the detection of unstable pubic SW, as well as OB pelvic injury, in polytraumatised patients. Inclusion of FAST-PLUS in patient management in the shock room may lead to a quicker identification of patients with unstable pelvis and to faster therapeutic work-up.
