A sling is a device used to support and keep still (immobilize) an injured part of the body. Slings can be used for many different injuries. They are most often used when you have a broken (fractured) or dislocated arm or shoulder.
- You may need a sling because of an injury or surgery to your hand, wrist, arm, or shoulder. A sling helps prevent your hand, arm, and shoulder from moving so your injury can heal. A sling can also help if you have a heavy cast on your arm.
