3. Perineal band.
4. Strapping, needle, and thread.
5. Pad and wool.
The splint for an adult should be 2½ or 3 inches wide, and long enough to reach from the nipple to 4 or 5 inches beyond the heel; two round holes ¾ inch diameter are cut at its upper end, and at the lower one two notches 2 inches deep.
Liston’s Mode of applying the Long Splint.
Step 1. The end of a roller is split for a few inches, and tied in the holes at the upper end. The roller itself is carried down the inside of the splint and attached temporarily to the notches at the other end; a pad is then fastened on, by drawing the margins together with needle and thread across the outside of the splint, or by tying strips of bandage round the pad and splint at short distances.
Step 2. The limb having been washed with soap and water, well dried, and afterwards dusted with starch powder, especially at the perinæum, the ankle and dorsum of the foot are wrapped in a layer of cotton wool, and the splint applied along the outside of the body. The bandage which was fastened to the splint is now released from the notch; and, taking with it the end of the pad, is carried under the sole, then over the ankle joint to the splint, and behind the ankle round the internal malleolus to the dorsum of the foot, then through the lower notch of the splint to the inside of the foot again. This figure of 8 is carried four times over the dorsum of the foot, twice through each notch of the splint, and is made fast by a pin or a stitch. In doing this, care must be taken to keep the leg and splint parallel, and that the splint does not ride over the back of the foot; the external malleolus should be midway between the margins; moreover, the bandage must fit firmly round the ankle and splint, not spreading over the dorsum more than can be helped, to avoid straining the front of the ankle. Means for more effectually preventing this will be afterwards detailed.
Step 3. Next apply counter-extension; for this, the perineal band is used. The band consists of a silk handkerchief or napkin folded into a flat ribbon, 1 inch wide and covered for about 1 foot of its length with oiled silk. A piece of smooth brown paper, 1 foot long and 4 inches wide, folded into a ribbon one inch wide, makes an excellent foundation for the silk handkerchief to be folded upon. A band thus prepared is too stiff to become a cord after it has been worn a few days, which a simple handkerchief is apt to do. One end of the band is passed in front in the groin, and one behind the buttock, so that it bears on the tuber ischii in the perinæum; the ends are then drawn separately through the holes in the splint. All being ready for extension, an assistant, grasping the leg and splint above the ankle, pulls out the shortening till the broken bone is in a good position; the ends of the band are then tightened and made fast in a knot.
Step 4. First protecting the bony points with cotton wool, the muscles about the hip are confined by a spica carried round the body and the splint, not merely a simple figure of 8 as depicted in the figure, but a series of overlapping turns which ascend and cover in the hips well. Afterwards the upper end of the splint is drawn close to the body by a few turns of a broad roller carried round the chest from above downwards (see fig. 48).
