Compound injuries are injuries caused by two or more injury-causing factors acting on the human body at the same time or in succession. For example, if a patient suffers a burn injury and at the same time suffers a smashing injury due to the collapse of an object, then the patient will have a simultaneous burn injury, a scalp laceration on the head, and a cranial hemorrhage, which is called a compound injury. It has two or more causative factors, and compound injuries tend to be more complex because it’s not just a simple addition of two traumas. Often the combination of these two or more traumas makes treatment more complex and problematic, so compound injuries have a higher mortality rate and sometimes conflicting treatment options are possible.
