Roll up a sleeping pad from both ends, leaving four to six inches between the two rolls.
Place a rolled-up T-shirt behind the patient’s knee.
Tie the pad around the patient’s leg using bandannas, shirts, or backpack straps. Don’t tie directly over the break.
Inflate the pad for extra support. When you’re done, check the patient’s toes for circulation and sensation. Loosen the splint if necessary.
