How do open and closed fractures differ?

• A. Open fractures are less dangerous than closed fractures.
• B. Open fractures can be treated at home without immobilization.
• C. Closed fractures always involve skin exposure.
• D. Open fracture breaks the skin and exposes bone; a closed fracture does not.

Answer: (D)

The key idea is the involvement of the skin and the resulting risk of infection. An open fracture means the bone has broken through the skin or there is a wound that exposes bone, so the injury is not just to the bone but also to surrounding tissues and a clearer route for bacteria. A closed fracture means the skin remains intact, even though the bone is broken. Because the skin is broken in an open fracture, there’s a higher risk of contamination, infection, and soft-tissue damage, and the person often needs more urgent medical care. That’s why the proper first-aid approach emphasizes protecting the wound with a sterile dressing, immobilizing the limb without moving the bone, controlling any bleeding, and seeking urgent medical treatment. For a closed fracture, since the skin isn’t breached, the immediate concern is still immobilization and evaluation, but the infection risk is much lower.
