The agreement between pelvic radiography alone and radiography with CT scan in determination of treatment of fractures of the pelvic ring

BackhroundsCT scan is one of the routine modalities in diagnosis of the pelvic fractures. Anunanswered question is if CT scan can alter treatment plane of these fractures MethodsAt first, radiographs of 100 patients with fracture of the pelvic ring were evaluated byone surgeon and type of the fracture according to Young and Burgess classification andtreatment plane (surgical or non-surgical) were identified. Then 3 months later thesame radiographs with CT scans were evaluated by the same surgeon and type andplane of treatment were determined again and Results were analyzed with SPSS 22.ResultsFractures of the pubic rami were the most common injury in radiography and CT scan.The least common injury in radiography was fracture of the ilium but in radiography andCT scan was diastasis of symphysis pubis. CT scan was more accurate than radiographyin diagnosis of the sacral fractures and crescent fractures of the ilium (p=0.000) butthere was no significant difference in classification of fractures. Non-surgical treatment was suggested for 63 patients and surgical for 37 patients according to radiography andwith adding of the CT scan, non-surgical treatment was suggesting for 69 and surgicalfor 31 patients and this difference was not significant again.ConclusionsAlthough CT scan gives more accuracy in diagnosis of the fracture lines, it cannot alterplane of the treatment
