A sling is a medical device used to support an injured or immobilized arm. It is typically made of a soft, flexible material, such as cloth or mesh, and is worn around the neck and shoulder. The injured arm is then placed in the sling, which helps to keep it in place and prevent further injury.
Slings are often used to treat a variety of injuries, including sprains, strains, fractures, and dislocations. They can also be used to immobilize an arm after surgery. Slings can help to reduce pain, swelling, and inflammation, and can also help to prevent the injured arm from moving out of place.
