In recent years there has been an increase in the use of backpacks and rucksacks by nonmilitary ary personnel. An estimated 3 million individuals engage in hiking and mountain climbing, and countless others use these packs on campus. We report a case of brachial plexus injury sustained by an individual wearing such a pack.
