1. Care for all wounds first before applying a splint.
2. An injured body part should usually be splinted in the position in which it was found.
3. Find something rigid to use as supports to make the splint such as sticks, boards, or even rolled up newspapers. If none can be found, use a rolled blanket or clothing. An injured body part can also be taped to an uninjured body part in order to prevent it from moving. For example, you can tape an injured finger to the finger next to it to keep it immobile.
4. Extend the splint beyond the injured area in order to keep it from moving. In general, try to include the joint above and below the injury in the splint.
5. Secure the splint with ties (belts, cloth strips, neckties, etc.), or tape above and below the injury (make sure the knots are not pressing on the injury). Avoid over-tightening which can cut off the circulation.
6. Check the area of the injured body part frequently for swelling, paleness, or numbness. If necessary, loosen the splint.
7. Seek professional medical attention.
DO NOT make any attempts to change the position of, or realign an injured body part.
If an injury occurs while out hiking, camping, etc., call for emergency medical assistance as soon as possible. In the meantime, administer first aid for the victim.
Any injury that involves bone protruding through the skin, a loss of sensation, or a loss of pulse beyond the injury requires immediate emergency medical assistance. If any of these situations occur, medical assistance is not available, and the injured part looks to be abnormally bent, gently replacing the injured part back into its normal position may improve the circulation.
