In avulsion or ballistic injuries, what is the purpose of debridement?

• A. To prevent infection
• B. To promote scarring
• C. To accelerate closure at all costs
• D. To remove only nonviable tissue without infection risk

Answer: (A)

The main idea here is that debridement in avulsion or ballistic injuries is done to prevent infection by removing dead tissue and contaminants and to create a clean wound bed for healing. Dead tissue and embedded foreign material can harbor bacteria and disrupt blood flow, making infection more likely and slowing healing. By excising nonviable tissue and thoroughly cleaning the wound, you lower the bacterial load and improve perfusion to the remaining tissue, which supports eventual closure. This isn’t about forcing rapid closure or removing as much tissue as possible; it’s about balancing removal of nonviable matter with preservation of viable tissue to optimize healing. The concept that the procedure would occur “without infection risk” isn’t accurate, since reducing infection risk is exactly why debridement is performed.
