The Medicare Adjustable Adult Arm Sling is a one-size-fits-all product designed to provide general arm support and restrict movement to assist in healing sore or injured arms and elbows. It helps to relieve pain and prevent re-injury. The adjustable shoulder strap makes it easy to use and simple to adjust. The strap distributes weight more evenly, while the arm cradle supports the forearm all the way to the fingers. This helps to keep the whole arm secure and comfortably immobilized. The arm sling is particularly useful for people who have had shoulder surgery or have injured their arm or elbow.
