What is called when a device is used to immobilize an injury?

The term for a device used to immobilize an injury is a splint. Splints are specially designed tools that can stabilize broken or injured limbs, preventing movement that could exacerbate the injury. They work by applying rigid support to the affected area, allowing the injured part to remain stationary while it heals.

In contrast, a bandage primarily serves to secure dressings over wounds or maintain support to an injured area but does not necessarily provide the same level of immobilization as a splint. A dressing is specifically aimed at protecting a wound and promoting healing rather than immobilizing an injury. A brace, while also used for support and stability, is generally less rigid than a splint and may be more flexible, permitting some movement, which is not the primary goal when it comes to immobilizing an injury effectively. Thus, the most accurate term for a device specifically intended to immobilize an injury is indeed a splint.
