ObjectiveTo investigate the clinical value of spiral CT with multi-planar reconstruction (MPR) and three diamensions reconstruction (3D) in the diagnosis and treatment of pelvic ring fractures.MethodsFifty-seven patients with pelvic ring fractures were examined with digital radiography and spiral CT in our hospital from April 2004 to April 2009. According to Tile classification, there were thirty-eight cases in type A, twelve in type B and seven in type C. Expectant treatment was used in type A, while surgery, open reduction internal fixation or percutaneous lag screw internal fixation technique for sacroiliac joint due to the displacement of fractures, for type B and C. Three days to twenty-seven months after operation, spiral CT examinations were used to evaluate the location of internal fixation. Cross-check analysis of images of digital radiography and spiral CT was performed before and after operation.ResultsFive posterior and three anterior pelvic ring fractures were diagnosed as suspected fractures. Nine posterior and three anterior pelvic ring fractures were missdiagnosed according to plain radiographs, which were corrected by spiral CT examination. According to the postoperative imageology evaluation, the results were excellent in 15, good in 3 and bad in 1. According to clinical evaluation, 16 cases were excellent, 3 good.ConclusionSpiral CT with multi-planar reconstruction (MPR) and three diamensions reconstruction (3D) has clinical values for precise diagnosis and treatment for the complex pelvic ring fractures.
