The authors review reference publications and discuss diagnostic intricacies in a case of a 7 year old boy with seatbelt syndrome. The syndrome concerns most commonly children aged 4 to 9 years. It results from injuries in communication accidents--and actuation of two-point seatbelts. Injuries concern both the abdominal cavity organs (i.e. intestines, mesentery) and lumbar segments of the spine--including Chances's fractures.
