Significance of clinical examination, CT and MRI scan in the diagnosis of posterior pelvic ring XXXX .

INTRODUCTION: @entity1 with a @entity174 in the anterior pelvic ring often simultaneously demonstrate @entity158 in the posterior pelvic ring. The aim of the present prospective study was to assess the sensitivity of CT, MRI and clinical examination in the detection of @entity174 in the posterior pelvic ring in @entity1 with @entity174 of the anterior pelvic ring diagnosed in conventional radiographs. METHODS: Sixty @entity1 with radiographic signs of an anterior pelvic @entity130 were included in this prospective analysis. Following a focused clinical examination of the posterior pelvis, all @entity1 underwent both a CT and then a MRI scan of their pelvis. Two board certified radiologists evaluated the CT and MRI scans independently. To estimate the presence of @entity170 the Hounsfield units of the vertebral body of L5 were measured in each case. RESULTS: Fifty-three @entity1 and seven @entity1 , with a mean age of 74.7+/-15.6 years were included into the study. A @entity174 of the posterior pelvic ring was found in fourty-eight @entity1 (80%) @entity1 using MRI. @entity174 would have been missed in eight cases (17%), if only CT had been used. Eighty-five percent of the @entity1 with a posterior @entity174 had an @entity170 . The majority of the cases suffered from a low energy @entity130 . Thirty-eight @entity1 (83%) with positive clinical signs at the posterior pelvic ring actually had a @entity174 of the posterior pelvic ring in the MRI. The clinical examination proved to be equally effective to CT in detecting posterior pelvic ring @entity174 . CONCLUSION: The significance of both, clinical examination and CT was confirmed in the detection of @entity174 in the posterior pelvic ring. MRI examination of the pelvis however, was found to be superior in detecting undislocated @entity174 in a cohort of @entity1 with a high incidence of @entity170 . Using MRI may be beneficial in select cases, especially when reduced bone density is suspected.
