Adventist Youth Honors Answer Book/First aid/Kneecap splint
Carefully straighten the injured limb. Immobilize the fracture by placing a padded board under the injured limb. The board should be at least 4 inches wide and should reach from the but- tock to the heel. Place extra padding under the knee and just above the heel, as shown in the illustration. Use strips of bandage to fasten the leg to the board in four places: (1) just below the knee; (2) just above the knee; (3) at the ankle; and (4) at the thigh. DO NOT COVER THE KNEE ITSELF. Swelling is likely to occur very rapidly, and any bandage or tie fastened over the knee would quickly become too tight. Treat the victim for shock and evacuate as soon as possible.
