ABSTRACT:
An arm sling is disclosed, having a waistband securable around the waist and a first strap attached to the front and back of the waistband and passable over the shoulder of the slung arm from the unslung side at the back of the waistband to the slung side of the front of the waistband. A second strap is attached to the back of the waistband and is passable over the shoulder of the unslung arm, first crossing the first strap. The first strap bifurcates into two support straps in the area of the slung arm, preferably approximately midway between the shoulder and the waist, to form a substantially triangular shape with the support straps supporting the slung arm at two spaced apart locations, the overall length of the strap and bifurcated support straps being sufficiently long so as to form a loop to cradle the slung arm. The first and second straps preferably are fastened to each other where they cross each other. The sling is preferably sewn and of cotton. The second strap may also have a bifurcated portion, and buckles may be provided at various locations for suitable size adjustments.
