AimPhysical examination and radiography of the pelvis is part of most routine protocols in the emergency room (ER) management of blunt trauma patients. The purpose of this study was to determine the usefulness of these diagnostic tests with respect to diagnostic accuracy, therapeutic consequences, and prognosis in severely injured patients.MethodIn a prospective study including all trauma patients admitted to the ER, physical examination and clinical management were evaluated. All patients underwent physical examination of the pelvis and were grouped into two categories: patients without (group I) and with (group II) clinical pelvic instability. A comparison between these two groups was made for standard demographic data, indices of shock, diagnostic and therapeutic procedures, and results.ResultsDuring a 45-month period a total of 1160 patients were enrolled: 979 subjects (ISS 21+/-16) with blunt trauma were included in this analysis. Of these, 929 patients had negative (group I) and 51 (group II) positive examination results for clinical stability of the pelvis. When comparing these two groups, group II patients had a higher injury severity score, higher incidence of shock with a lower initial systolic blood pressure, a lower initial hemoglobin, and a higher rate of associated severe chest and abdominal injuries (AIS > or = 3). Among the 51 patients with abnormal pelvis instability, there were 6 type A, 16 type B, and 27 type C fractures, whereas in two cases no pelvic fracture could be found. Of the 928 patients without positive clinical signs, 866 (93%) had no pelvic fracture. There were 40 type A, 19 type B, and 3 type C fractures missed on clinical examination. The physical examination had a sensitivity of 44% and specificity of 99% for detecting pelvic fracture. A comparison between groups I and II showed the patients with positive physical pelvic examination to have greater transfusion requirements and a higher rate of surgical intervention for pelvic stabilization and blood control.ConclusionThe clinical diagnosis of pelvic instability should result in an immediate order for blood products, taking surgical intervention into account. Pelvic radiographs in the ER are required for early surgical management. In patients with negative pelvis examination results, a routine pelvic radiograph is recommended because clinical examination cannot reliably rule out surgically significant pelvic fractures (20%) in the severely injured and intubated blunt trauma patient.
