The use of a collar and cuff sling is common in children for a variety of upper limb problems. Unfortunately, the single loop around the neck can cause problems as the upper limb can swing around often requiring the sling to be worn beneath clothes. The child can remove the sling and there are concerns about safety and the risk of asphyxiation. By including the good arm in the neck loop (Fig. 1) the sling does not allow so much movement, prevents removal and guards against asphyxiation. This is useful in the young when compliance may be poor.
