Injury investigations in road accidents : typology, factors and mechanisms and minor lesions characteristics. (AIS< 3).

The severity index used for injuries allows a direct estimation of the vital risk, but cannot be used to specify what role the minor lesion play, in worsening and invalidating. A homogenous sample must be studied in order to clarify the epidemiology and the consequences of such injuries. Therefore 262 cases were studied and the results are presented.
