Book excerpt: During the course of the Iraq and Afghanistan Wars, military orthopedic surgeons have made significant technical and philosophic changes in the treatment of musculoskeletal combat casualties. The widespread use of individual and vehicular body armor, evolution of enemy tactics to include its reliance on improvised explosive devices, and the effectiveness of treatment rendered at military treatment facilities have resulted in a large burden of complex orthopedic injuries. Combat Orthopedic Surgery: Lessons Learned in Iraq and Afghanistan represents and recognizes the latest advances in musculoskeletal surgical care performed to treat today’s US military servicemembers. Editors LTC Brett D. Owens, MD and LTC Philip J. Belmont Jr., MD have brought together the leading military orthopedic surgeons to relay their clinical orthopedic surgery expertise, as well as to discuss how to provide optimal care for combat casualties both initially in theater and definitively at tertiary care facilities within the United States. Combat Orthopedic Surgery: Lessons Learned in Iraq and Afghanistan is divided into five sections, with the first being devoted to an overview of general topics. The second section covers scientific topics and their clinical application to musculoskeletal combat casualties. The final three sections are clinically focused on the upper extremity, lower extremity, and spine and pelvic injuries, with many illustrative case examples referenced throughout. Most clinical chapters contain: Introduction/historical background Epidemiology Management in theater Definitive management Surgical techniques Outcomes Complications Combat Orthopedic Surgery: Lessons Learned in Iraq and Afghanistan will be the definitive academic record that represents how orthopedic surgeons currently manage and treat musculoskeletal combat casualties.
