Assess for fracture (see "How to Assess for Fracture").
Step2
Immobilize the injury: any movement is not only very painful but also can worsen the injury.
Step3
Find some rigid yet flexible material long enough to extend at least from the middle of the lower leg on one side of the fractured ankle to the middle of the lower leg on the other side. One possibility is to cut an Ensolite sleeping pad to the proper length and then fold it over to increase rigidity.
Step4
Gather materials to tie the splint into place. Any of the following will do: pack straps, rope, clothing, belts, bandannas, triangular bandages.
Step5
Make a U-shaped splint: run the splinting material from one side of the lower leg, around the foot at the arch, to the other side of the lower leg. This forms a sort of stirrup.
Step6
Tie the splinting material into place.
Step7
Place padding in any empty spaces between the splint and the leg or foot.
Step8
Check circulation, sensation and motion beyond the fracture sight, to make sure the splint isn't too tight.
Step9
Continue with further treatment for the fracture (see related eHows on treating fractures).
Tips & Warnings
Contact the Wilderness Medicine Institute or the National Outdoor Leadership School for information on wilderness medicine courses and books.
Don't tie on the splint too tightly. This could impede circulation.
