10 Similar again in great part are accidents to the upper arm and thigh and their treatment; there are also some points common to the arms, forearms, thighs, legs and digits, since there is least danger when the middle of the bone is fractured. The nearer the fracture is to either the upper or the lower end the worse it is; for they are at once more painful and more difficult to treat. The least troublesome is the simple transverse fracture; the multiple and the oblique are worse; the worst are those where the fragments are pointed. Now sometimes the fractured bones in these cases remain in their places; but much more often they slip out and overlap each other; this is the first question to be decided, and the signs are unmistakable. If the fragments are in contact, they make a sound when moved and produce a stabbing sensation; they are not level to the touch. But if they are in touch not directly but obliquely, which happens when the fragments are not in their place, that limb will be shorter than the other, and its muscles swell up. Therefore if this has been noted, the limb ought to be stretched at once; for the sinews and muscles which the bones keep on the stretch are contracted, and do not come into their proper place unless someone forces them into position. Moreover if this is not done at first, inflammation sets in; during which it is both difficult and dangerous to employ force to the sinews; for either spasm or gangrene follows, or, even if the case goes very favourably, suppuration. Therefore if the fragments have not been replaced before the inflammation, this must be done after. Now a finger or any other limb that is still supple can be stretched by one man alone, when he takes one end with his right, the other with his left hand: a stronger limb requires two men to pull in op directions. If the sinews are more resistant, as in powerful men, especially in their thighs and legs, leather straps or linen bands are to be put round each end of the joints, and pulled in opposite directions by several persons. When by force the limb has been made a little longer than it should be, then at length the bones must be pushed back into their place by the hands. A sign of the replacement is that the pain disappears, and the limb becomes equal to the other. Then cloths folded over two or three times and dipped in both wine and oil are wrapped round the part, and it is best for these to be of linen. Generally six bandages are needed. The first, a very short one, is to make three turns over the fracture in the form of a spiral carried upwards; three such turns are sufficient. The second bandage, half as long again, should begin over any projection if there is one; if the bone is quite smooth, it may begin anywhere over the fracture, in an opposite direction to the first bandage, and go downwards, then back over the fracture to end above the first bandage. Over these two bandages is spread a cerate on a broader layer of lint in order to hold the bandages in place; and if at any point bone projects, a triple layer of wool, soaked in wine and oil, is put over it. The foregoing are surrounded by a third bandage, and then by a fourth, the turns always following a direction the reverse of the bandage underneath. The third bandage ends below, the other three above the fracture. It is better to make the turns of the bandage numerous rather than tight, for a part which is constricted is damaged and disposed to gangrene; now a joint should be bandaged as little as possible, but this is necessary if the bone is fractured close to it. The limb should be kept bandaged until the third day: and it ought to be so bandaged that on the first day, whilst it does not hurt, yet it should not seem to be slack; on the second day it should be slacker, and on the third almost loose. Then the limb must be bandaged again, and a fifth bandage added to the others; on the fifth day the bandaging should be undone, and the limb wrapped in six bandages, put on so that the third and fifth bandages finish below, the others ending above. And, whenever the limb is uncovered, it is to be fomented with hot water. But if the fracture is near a joint, from time to time wine with the addition of a little oil is to be dropped into it, and the same treatment is continued until the inflammation has subsided or the limb has become even a little smaller than ordinary. This occurs by the seventh, or certainly by the ninth day; then the bones are easily manipulated. Therefore if not yet in place, they should be put back; if any fragments project, they must be pushed back into position; then the limb is to be bandaged as before, and over the fracture splints are arranged above so as to hold the fragments firmly in position; and the broader and stronger split is put on the side to which the fractured ends tend to deviate. All these splints should all be bent opposite to a joint so as not to injure it, and they should not press more than is requisite to hold the fragments in place; and since after a while they become loose, every third day the straps keeping them in place are tightened; if there is no itching, or pain, they are kept on for two-thirds of the time which it takes for such a fractured bone to unite; after that the part is fomented lightly with hot water, for the diseased matter must be first dissolved, than extracted. For this reason there should also be gentle inunction with liquid cerate, and superficial rubbing; and the bandaging should be looser. Every third day this bandage is removed, and omitting the hot fomentations, the same treatment is carried out, such that at each change there is one bandage less.
