HypothesisAnalysis of the current injury situation in road users not exceeding 14 years of age involved in road traffic accidents to allow conclusions regarding future prophylaxis.MethodsTraffic accident reports and medical records from children (< 15 years of age) were analyzed for the following parameters: Type, location and mechanism of injury, Abbreviated Injury Scale (AIS), Maximum AIS (MAIS), Injury Severity Score (ISS), Delta-v, collision speed, type and duration of treatment.ResultsIn 12,309 traffic accidents occurring in the area of Hannover, Germany between 1985 and 1998, 7.5% (n = 2,317) of the involved persons and 10.5% (n = 1,734) of the injured road users were children and adolescents. 70% sustained MAIS 1 injuries, 28% MAIS 2-4 and 1.5% MAIS 5/6 injuries. The mean ISS was 3.38. 30.3% of the injured children were car occupants, 32.1% bicyclists, 33.3% pedestrians. 30.3% of the children were unrestrained car occupants, 42.1% used safety belts designed for adults, 36% used special devices. Half of the children in cars remained uninjured, whereas only 8% of the bicyclists and 2% of the pedestrians were not injured. Severe injuries occurred in 20% of bicyclists and pedestrians at a collision speed less than 30 km/h and in 80% at more than 50 km/h. Half of those crashes could have been avoided, if the colliding vehicle would had driven about 15 km/h slower.ConclusionChildren have an especially high risk of injury if they are involved in accidents as pedestrians, bicyclists and unrestrained car occupants. Besides of improvements of the inner and outer car design, the use of adjusted restraining systems and bicycle helmets is likely to prevent from severe injuries. Speed reduction is a considerable factor. According to our data, the injury severity for bicyclists and pedestrians increases progressively when the collision speed exceeds 50 km/h.
