Harris Mark S. Rountree Lanny V. Griffin Roman A. Hayda Terry Bice Stephen J. Mannion U.S. Army Institute of Surgical Research Extremity Trauma Study Branch Fort Sam Houston, Texas Abstract Research conducted by Department of Defense laboratories and facilities, collaborating with leading academic institutions, has demonstrated that currently available landmine protective footwear does not prevent severe injury. This footwear potentially reduces injury severity against some antipersonnel mines. Volume 2 of the Lower Extremity Assessment Program (LEAP 99-2) discusses the change of injury pattern in a cadaver model wearing mine protective footwear during an antipersonnel blast mine detonation. Our analytical methodology developed to assess mine-protective footwear and injury severity associated with blast mines across the spectrum of threat is presented. iii iv Table of Contents Item Page
