Abstract
Background: Throughout history, traumatic amputation of the lower extremity has been a notable feature of all conflicts involving explosive incidents. Even at the close of the recent conflicts in Afghanistan, there were deaths that were deemed "potentially survivable." The purpose of this study is to characterize lower extremity blast injury and to determine if their amputation levels and associated injury characteristics correlate with a higher risk of mortality.
Methods: the UK Joint Theatre Trauma Registry (JTTR) was interrogated to identify all lower extremity traumatic amputations sustained in both Iraq and Afghanistan between January 2003 and the end of UK operations in August 2014. The mortality rates for each amputation level and associated injuries were determined.
Findings: Of the 977 casualties, there were 679 (69.5%) survivors and 298 fatalities (30.5%). There was an increase in survivability from traumatic amputation throughout the conflict, however, traumatic amputations at the close of military activity in 2014 still had a substantial fatality rate of 23%. A more proximal level of amputation, an associated pelvic fracture, and an associated abdominal injury all correlated with an increased mortality rate.
Discussion: Several specific injury characteristics associated with traumatic amputation have been identified that are associated with an increased mortality rate to include a more proximal amputation level, pelvic fracture, and abdominal injury. Injury prevention and mitigation measures should be explored to minimize the risk of the associated injuries following blast that portend a higher risk of mortality.
