1) Polytrauma refers to multiple injuries that affect multiple body systems and can lead to organ dysfunction or failure. It requires management by a team of surgeons and physicians, including an orthopedic surgeon.
2) The priorities in managing polytrauma are life salvage, limb salvage, and salvaging total function if possible. This involves controlling hemorrhage, treating life-threatening injuries, and splinting fractures while avoiding further injury.
3) Damage control orthopedics focuses on rapidly stabilizing fractures to control bleeding and prevent further tissue injury, while delaying more definitive fixation to avoid exacerbating the body's inflammatory response in critically injured patients.
