Radiographic assessment of pelvic trauma.

Assessment of pelvic fractures requires an understanding of the bony and soft-tissue anatomy of the pelvis. Pelvic injuries may be classified into major and minor groups. Minor fractures usually result from athletic trauma in the young or falls in the elderly and can generally be adequately evaluated with routine radiography. Major fractures are most often caused by motor vehicle accidents, falls from a height or industrial accidents and require more sophisticated examination. However, the investigation of injuries in either category should be directed by a knowledge of the history and physical findings. The classification of pelvic injuries used at Sunnybrook Medical Centre is based on mechanisms of injury.
