What should be filled to stabilize an injury during splinting?

Filling the voids to immobilize is essential during splinting because it helps stabilize the injured area. When splints are applied, any gaps between the splint and the injured body part can lead to movement, which may exacerbate the injury or cause further damage. By filling these voids, the splint becomes more effective in limiting motion, providing support, and promoting healing. Proper immobilization can also help reduce pain and the risk of complications.

The other options do not effectively contribute to stabilizing an injury in the context of splinting. Filling holes around the injury or open wounds does not address the need for immobilization. Similarly, using ice can help reduce swelling or pain but does not assist in stabilizing the injury itself during the splinting process. Hence, focusing on filling voids ensures that the splint provides the necessary support to keep the injured area stable and protected.
