Injury Severity Score Orthoteers

Description: The Injury Severity Score was developed in 1974 by Baker et. al. from Abbreviated Injury Scale to evaluate motor vehicle victims with multiple injuries.
* The Injury Severity Score (ISS) was used to compare the severity of injuries with an original study group of 2,128 victims, it was observed that the mortality increased with the AIS grade of the most severe injury.
* The mortality increased with regular increments when plotted against the square of the AIS grade (a quadratic relationship).
* When the victims with identical AIS grades for their most severe injury were compared, injuries in the second and third body regions tended to increase the risk of death. The Injury Severity Score was therefore defined as " the sum of the squares of the highest AIS grade in each of the three most severely injured areas ".
