Blast and fragment injuries of the musculoskeletal system

Blast and fragment injuries of the musculoskeletal system are the most frequently encountered wounds in modern warfare. Most injuries to the musculoskeletal system involve so-called secondary blast injuries in which casing fragments and other debris become flying projectiles. Nonoperative treatment of selected wounds caused by small-fragment debris has been successful but remains controversial. Successful surgical treatment depends on meticulous wound débridement, with excision of nonviable tissue and foreign material likely to cause infection; adequate drainage; and delayed closure. Advanced internal fixation techniques used in modern trauma centers to treat predominantly blunt trauma may not be appropriate for care of orthopaedic war wounds in a field setting.
