The case is a good deal worse, when, besides the fracture of the bone, there is also a wound in the flesh; and particularly if that happen in the muscles of the thigh or arm: for the inflammations there are much greater, and they are more liable to gangrenes. And generally, where the bones of the thigh have slipped past each other, it is necessary to cut it off. The arm is also endangered in the same circumstances, but is more easily preserved. And these dangers are still more to be apprehended, if the fracture be near the joints: therefore, such a case must be treated with more care, and the muscle must be cut through transversely over the middle of the wound; and if the hæmorrhage has been but small, the patient must be bled, and extenuated by fasting for ten days. And though the other limbs may be extended slowly, and the bones reduced gently to their place; yet in these it is not quite expedient either to extend the tendons, or handle the bones. And the patient must be allowed to keep them in the position that is easiest to him. To all such wounds must be applied, at first, lint dipped in wine, with an addition of a very little rose oil: the other management is the same as above recommended. They are to be bound up with rollers broader[(19)] than the wound; which must be applied looser, than if there was not a wound there; and as the wound is more liable to corruption and a gangrene, we are by a number of rollers to manage it so, that though they are slack, they may keep the bones firm.

This method may be followed in the thigh or arm, provided the bones have chanced to return to their proper place; but if they be in any different situation, they must only have such a bandage, as will keep on the medicine that is applied. The other directions I gave before must be observed: except that neither splints nor boxes be used, with which the wound cannot heal; but only more and broader rollers are necessary; and both hot oil and wine must be poured upon them now and then; more frequently the latter. At the beginning the patient must fast; the wound must be bathed with hot water; he must avoid the cold; and recourse must be had to medicines for promoting digestion of the wound, and more care must be taken of the wound than the bone: for that reason it must be opened every day and dressed.

In the mean time, should any small fragment of the bone project, if it be blunt, it must be reduced into its place; if sharp, its point, when long, must first be cut off, when short, filed, and in either case smoothed with a chisel; and then it must be returned in again. And if that cannot be done by the hand, a vulsella, such as workmen make use of, must be applied with that part[(20)] which turns inward to the sharp point of the bone, that by its convex part the prominent bone may be thrust into its place. If it be too large, and covered by small membranes, we should allow these to be dissolved by medicines, and when the bone is laid bare, cut it off; which is to be done pretty early, and afterwards, in this method we may let the bone unite and the wound heal; the first in its proper time, and the other as the circumstances admit.

Sometimes too it happens in a large wound, that some fragments as it were mortify, and do not unite with the rest. This may be discovered from the quantity of discharge; which makes it necessary to open the ulcer oftener than it is dressed; and the consequence generally is, that this bone, after some days, of itself falls off; otherwise, though the condition of the wound is miserable enough before, that often encreases it, and makes it more tedious of cure. The bone too is often broken away, when the skin is entire, and immediately an itching and pain come on. Wherefore, if that happens it is proper to open it the sooner, and bathe it in the summer time with cold water; and in the winter with water just warm; and then apply myrtle cerate.

Sometimes, the fracture, by some points like prickles, irritates the flesh: which being discovered by the itching and prickings, the physician must open it, and cut off these points. The other part of the cure is the same in both these cases as in a recent wound. When the ulcer is clean, nourishing food must be taken. If the limb is still too short, and the bones are not in their places, a wedge of the smallest and smoothest kind must be put in between them with its head standing out a little, and the thick part of it must be driven farther in every day, till that limb be equal to the other. Then the wedge must be taken out, and the wound healed up. When a cicatrix is brought on, it must be bathed with a decoction of myrtle, ivy, and other like vervains, cold, and a drying medicine applied upon it; and in this case, there is a greater necessity for rest, till the limb recover its strength.

When the bones happen not to unite, because they have been often opened, and often moved, the method of cure is obvious; for they may unite. If the fracture be of long standing, the limb must be extended, to create a fresh injury; the bones must be separated from one another by the hand, that their surfaces may be roughened by rubbing against each other, and if there be any fat substance, it may be abraded, and the whole of it become as it were recent: great care, however, must be taken not to wound tendons or muscles. Then it must be bathed with a decoction of pomegranate bark in wine; and the same mixed with the white of eggs, must be applied to it; on the third day it must be opened, and bathed with a decoction of the vervains abovementioned: which must be repeated on the fifth day, and splints put round it; the other steps, both before and after, which I directed already, must be taken in the same manner. However, sometimes the bones unite obliquely[(21)]; and thus the limb becomes both shorter and deformed, and if the ends are pretty sharp, continual prickings are felt: for this reason the bones ought to be fractured again, and put in a proper direction. It is done in this manner. The limb is fomented with plenty of hot water, and rubbed over with liquid cerate and extended; in the mean time, the physician handling the bones, the callus being yet tended, separates them by his hands, and forces the part that projects, into its place: and if that is not effectual, on that side, to which the bone inclines, he puts a regula wrapped up in wool; and by thus binding it up brings it to a habit of lodging in its former place.

Sometimes also, though the bones have united as they should do, too large a callus grows upon them; and therefore the part is swelled. When this happens, the limb must be rubbed gently for a long time, with oil, salt and nitre, and bathed with plenty of salt water; a discutient malagma must be applied; and a tight bandage put on; and the patient must eat herbage, and take vomits; by which course, the callus is reduced together with the flesh. Some good is done by an application of mustard and a fig upon another limb, till it corrode a little, and derive the matter to that part. When the tumour is lessened by these means, the person may return to his ordinary course of life.

CHAP. XI. OF LUXATIONS.

Thus far then we have treated of fractures. Now the bones are dislocated in two ways. For sometimes those that are joined together, separate from each other, as when the broad bone of the scapula recedes from the humerus[(22)], and in the fore-arm the radius from the cubitus, and in the leg, the tibia from the fibula, and sometimes in leaping the heel-bone from the ancle; which last, however, seldom happens. Sometimes the articulations are displaced. I shall speak first of the former.

When such an accident happens, the part is immediately hollow, and by pressing upon it with the finger one feels a cavity. After that, a violent inflammation comes on; and particularly in the ancle; for generally it occasions fevers and gangrenes, and either convulsions, or contractions, which draw the head down upon the shoulders. To avoid which, the same method must be followed here, as in injuries of the moveable bones. And whenever it happens, the medicines prescribed before must be laid on these parts to remove the pain and tumour: for bones once separated in this manner never come together again; and though some degree of comeliness be attainable in the part, yet it is of no use[(23)].
