Which splinting device is MOST appropriate to use for an open forearm fracture with external bleeding?

• A. Cardboard splint
• B. Sling and swathe
• C. Air splint
• D. Vacuum splint

Answer: (D)

When a fracture is open and there’s external bleeding, the priority is to stop the bleeding without causing further injury and to immobilize the limb so the fracture fragments don’t move. The splint chosen should provide solid immobilization, distribute pressure evenly, and accommodate swelling and an irregular limb shape without pressing on the wound.

A vacuum splint fits this goal best. It is molded to the forearm and, once air is removed, becomes a rigid support that limits movement of the bones and soft tissues. This stable, contour-matching support helps keep the fracture alignment and reduces pain while transporting the patient. It also distributes pressure gently around the injured area and around the wound, minimizing the risk of pressing directly on the open wound or causing additional tissue damage. The device is relatively quick to apply, works well even with swelling, and maintains immobilization as the injury evolves.

In contrast, a cardboard splint is unreliable and easily deforms; a sling and swathe mainly supports the arm but does not adequately immobilize the forearm or protect an open wound; an air splint can be bulky and less stable, potentially shifting and applying uneven pressure. Therefore, the vacuum splint offers the strongest combination of immobilization, wound protection, and adaptability for an open forearm fracture with external bleeding.
