Abstract
Abstract An orthopedic arm sling made of a lightweight fabric material which has a front apron, the bottom of which is secured to the top to form a cradle extending the length of the arm. The supporting straps extend over the shoulders, cross the wearer's back and engage the edges of the apron to secure the apron and the arm to the wearer's body and keep the weight from being borne by the neck of the wearer. Optionally a restraint strap secures the arm from horizontal movement.
