Adventist Youth Honors Answer Book/First aid/Ankle splint

The figure-eight  bandage  is used  for dressings  of  the  ankle,  as  well  as  for  supporting a sprain. While keeping the foot at a right angle, start a 3-inch bandage around the instep for several turns to anchor it. Carry the bandage upward over the instep and around behind the ankle, forward, and again across the instep and down under the arch, thus completing one  figure-eight. Continue  the   figure-eight   turns, overlapping  one-third  to  one-half  the  width  of  the bandage and with an occasional turn around the ankle, until the compress is secured or until adequate support is obtained.
