A sling is a device used to support and immobilize an injured part of the body (in particular, an injured shoulder, arm, or collarbone).
If an injury needs a splint, apply the splint first, and then apply the sling.
Always check the person's circulation (skin color and pulse) after the injured body part has been immobilized.
Slings can be used for many different injuries, but most typically for arm or shoulder fractures, or dislocations. Any time there is a broken bone, stabilizing the area is important.
