The objective was to determine if head injury patterns and severity differ between frontal and side impact motor vehicle crashes (MVC). Subjects for the current study were selected from the CIREN database from 1997-2001. There were a total of 188 subjects enrolled of which 174 had an injury severity score (ISS) of >9. Frontal impacts were defined as those impacts between 11 and 1 o’clock. Side Impacts were defined as those on the same side as the occupant and collision deformation code lateral with impact between 8 and 10 o’clock or 2 and 4 o’clock. Head injury was defined as an AIS score greater than or equal to 3. Fifty-eight occupants met the head injury criteria of the 174 occupants studied. Type of head injury was evaluated as well as incidence of head injury. Restraint use, Vehicle type, occupant weight, age, intrusion and delta-V were analyzed for possible correlation with head injury incidence. (Author/publisher)
