Proper splinting may reduce pain. The less movement of the affected area, the better. To design a splint, use a rigid material such as wood, plastic or metal. The splint should be longer than the bone it is splinting and extend below and above the injury. Pad the splint with gauze wherever possible.
Pads make the splint more comfortable and help keep the bones straight.
Fasten the splint to the limb with gauze or strips of cloth or string. Start wrapping from the extremity and work toward the body. Splint the limb firmly to prevent motion but not tight enough to stop blood flow. Wrap a sling over the shoulder and a band around the sling to help keep the elbow still. If no splints are available, use the healthy leg as a splint to impede movement of the broken one.
