An arm sling is a medical device designed to support and immobilize the arm following an injury or surgery. It is commonly used for conditions such as fractures, dislocations, and sprains, as well as post-surgical recovery. The sling helps to reduce pain and prevent further injury by keeping the arm in a stable position. There are different types of arm slings, including standard slings, shoulder immobilizers, and pediatric slings for children. Proper use involves ensuring a comfortable fit, with the elbow at a right angle and the hand slightly elevated. Adjusting the straps properly is crucial to avoid pressure on the neck and shoulder. Always follow medical advice on the duration and manner of use to ensure effective healing.
