The MangLE score: A novel simple tool to identify patients who are unlikely to require amputation following severe lower extremity injury.

Background: There are no validated and sensitive models that can guide the decision regarding amputation in patients with mangled lower extremities. We sought to describe a simple scoring model, the Mangled Lower Extremity (MangLE) score, which can predict those who are highly unlikely to need an amputation as a means to direct resources to this cohort.

Methods: This is a retrospective study using the 2013-2021 American College of Surgeons Trauma Quality Improvement Program data set.
