Pelvic fractures. Assessment by conventional radiography and CT.

Sixty-two patients with pelvic fractures were evaluated by conventional radiography and CT. A correct pathoanatomic classification of the fractures was most often obtained by conventional radiography, but CT added information regarding acetabular fractures and involvement of the posterior part of the pelvic ring. Besides, CT was essential in the detection of intraarticular fragments and lesions of the femoral head. Classification of pelvic ring fractures by the pattern of traumatic forces was easily obtainable by conventional radiography, but often difficult to achieve by CT.
