Examining the history of arterial repair, Of Life and Limb investigates the process of surgical innovation by exploring the social, technological, institutional, and martial dynamics shaping the introduction and adoption ofa new operation. In 1880, patients suffering from vascular disease faced amputation -- or death. By 1960, a suite of revolutionary techniques and technologies empowered surgeons to remedy aneurysms, mend damaged vessels, and treat arteries cloggedwith cholesterol, saving the lives and limbs of patients around the world. Tracking this remarkable transformation, Of Life and Limb: Surgical Repair of the Arteries in War and Peace, 1880-1960 reveals how social, technological, institutional, and military dynamics interplay to catalyze modern surgical innovation. Author Justin Barr examines each of these phenomena through the complementary perspectives of academic historian andclinical surgeon, marshaling extensive research and incisive analysis into a broadly applicable model that helps frame, illuminate, and forecast change in surgery. Justin Barr received his PhD in History from Yale University and his MD from the University of Virginia. He is currently in residency for general surgery at Duke University.
