A convenient splint consists of heavy pasteboard wet and covered with sheet wadding (or cotton batting) shaped and affixed to the back of the leg, from six inches below to four inches above the joint, by strips of adhesive plaster, as shown in the illustration, and then by bandage, leaving the knee uncovered for applications. A wooden splint well padded may be used instead.
In mild cases without much inflammation, and in others after the tenderness and heat have abated, the patient may go about if the knee is treated as follows: a pad of sheet wadding or cotton batting about two inches thick and five inches long and as wide as the limb is placed in the hollow behind the knee, and then the whole leg is encircled with sheet wadding from six inches below to four inches above the knee, covering the joint as well as the pad. Beginning now five inches below the joint, strips of surgeon's adhesive plaster, an inch wide and long enough to more than encircle the limb, are affixed about the leg firmly like garters so as to make considerable pressure. Each strip or garter overlaps the one below about one-third of an inch, and the whole limb is thus incased in plaster from five inches below the knee to a point about four inches above the joint.
An ordinary cotton bandage is then applied from below over the entire plaster bandage. When this arrangement loosens, the plaster should be taken off and new reapplied, or a few strips may be wound about the old plaster to reënforce it. The patient may walk about with this appliance without bending the knee.
When the swelling has nearly departed, the plaster may be removed and the knee rubbed twice daily about the joint and the joint itself moved to and fro gently by an attendant, and then bandaged with a flannel bandage. Painting the knee with tincture of iodine in spots as large as a silver dollar is also of service at this time. The knee should not be bent in walking until it can be moved by another person without producing discomfort.
Such treatment may be applied to the other joints in a general way. The elbow must be fixed by a splint as recommended for dislocation of the joint (p. [128]). The ankle is treated as advised for sprain of that joint (p. [68]). When a physician can be obtained no layman is justified in attempting to treat a case of water on the knee or similar affection of other joints.
BUNION AND HOUSEMAID'S KNEE.—Bunion is a swelling of the bursa, or cushion, at the first joint of the great toe where it joins the foot. It may not give much trouble, or it may be hot, red, tender, and very painful. It is caused by pressure of a tight boot which also forces the great toe toward the little toe, and thus makes the great toe joint more prominent and so the more readily injured.
A somewhat similar swelling, often as large as an egg, is sometimes seen over the kneepan, more often in those who work upon their knees, hence the name housemaid's knee. The swelling may come on suddenly and be hot, tender, and painful, or it may be slow in appearing and give little pain.
Treatment.—The treatment for the painful variety of bunion and housemaid's knee is much the same: absolute rest with the foot kept raised, and application of cloths kept constantly wet with ice or cold water; or a thick covering of Cataplasma Kaolini (U. S. P.) may be applied until the inflammation has subsided. If the trouble is chronic, or the acute inflammation does not soon abate under the treatment advised, the case is one for the surgeon, and sometimes requires the knife for abscess formation. In the milder cases of bunion, wearing proper shoes whose inner border forms almost a straight line from heel to toe, so that the great toe is not pushed over toward the little toe, and painting the bunion every few days with tincture of iodine, until the skin begins to become sore, will often be sufficient to secure recovery.
RUN-AROUND; WHITLOW OR FELON.—"Run-around" consists in an inflammation of the soft parts about the finger nail. It is more common in the weak, but may occur in anyone, owing to the entrance of pus germs through a slight prick or abrasion which may pass unnoticed. The condition begins with redness, heat, tenderness, swelling, and pain of the flesh at the root of the nail, which extends all about the nail and may be slight and soon subside, or there may be great pain and increased swelling, with the formation of "matter" (pus), and result in the loss of the nail, particularly in the weak.
Whitlow or felon is a much more serious trouble. It begins generally as a painful swelling of one of the last joints of the fingers on the palm side. Among the causes are a blow, scratch, or puncture. Often there is no apparent cause, but in some manner the germs of inflammation gain entrance. The end of the finger becomes hot and tense, and throbs with sometimes almost unbearable pain. If the inflammation is chiefly of the surface there may be much redness, but if mainly of the deeper parts the skin may be but little reddened or the surface may be actually pale. There is usually some fever, and the pain is made worse by permitting the hand to hang down. If the felon is on the little finger or thumb the inflammation is likely to extend down into the palm of the hand, and from thence into the arm along the course of the tendons or sinews of the muscles. Death of the bone of the last finger joint necessitating removal of this part, stiffness, crippling, and distortion of the hand, or death from blood poisoning may ensue if prompt surgical treatment is not obtained.
