Use whatever you have at hand –a coat pillow, folded blanket, magazine, or perhaps several newspaper folded together. These are all useful as temporary splint. Sticks, branches from trees, umbrellas, walking sticks, metal tools, broom handles, wide boards – any of these may serve in an emergency. The main things is to hold the broken fragments steady preventing unnecessary movement.
Be sure the splint is well padded where it touches the skin. Use any soft material for this purpose. Support the fractured limb, using a sling or other means wherever indicated. If the victim’s back is injured, remove a door, or secure a wide board. So you may carry him to safety. Place the board beside him on the ground, and gently roll him onto the board. Take care not to bend the back in any way. He can then be carried to the nearest hospital or doctor’s emergency room.
