“…An editorial comment in The Annals of Surgery in 1919 concerned 30 cases of projectiles retained in the chest; 15 symptomatic patients with major psychological concerns about a metallic foreign body embedded in their chest, underwent surgery. 4 In 1941, Nixon 5 tailored his conflict injury management according to the climate, soil, and weapons. He found a lower incidence of empyema in cases of retained bullets or shells than in cases with no retained foreign body in the chest (16% vs. 41%), and blamed rib fractures and soft tissue lacerations for sepsis, and the climate of the battlefield more than the nature of the weapon.…”
