Begin by sitting with your arm propped up on a cushion. Slip the sling over your wrist and insert your thumb into the thumb-loop. Slip the sling over your forearm so that your elbow fits snugly into the sling's corner. Cross your back and over your wounded shoulder with the shoulder strap. Adjust the strap so that it is comfortable but not too tight. Put on some easy-walking shoes that have no straps or heels. You will be wearing this sling for several weeks after your surgery. When you go out in public, be sure to keep your injured arm inside the car door or else risk being arrested for criminal negligence. Slings are useful tools for helping to heal broken bones. They should never be used as an alternative to medical treatment. If you are still recovering from surgery, a physical therapist can help you learn how to put on and take off a sling correctly.
