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.
