The role of computed tomography in pelvic fractures.

Adequate radiologic demonstration of the extent of pelvic fractures facilitates planning of their treatment by the orthopedic surgeon. Traditionally, this evaluation has been by conventional radiology. This report details results of computed tomography (CT) in the evaluation of pelvic fractures in 34 patients. In most cases, CT was able to identify and delineate the extent of fractures, demonstrate displacement of the involved bones, localize bone fragments and characterize joint derangements. Many of these features were better demonstrated at CT compared with conventional radiographs. In particular, in 10 patients loose bodies were seen at CT that were not evident on conventional radiography. The extent of associated soft tissue injury is also well shown by CT and demonstrated peripelvic or intraarticular fluid collections can be aspirated under CT guidance to rule out sepsis. This study suggests that CT is useful in the assessment of major pelvic fractures.
