5 1 Missiles28 too, which have entered the body and become fixed within, are often very troublesome to extract. And some of the difficulties arise from their shape, some owing to the positions to which they have penetrated. Whatever the missile may be, it is extracted, either by the wound of entry, or through the spot towards which it is pointing. In the former case, the missile has already made a way for its withdrawal; in the latter the way out is made with the scalpel; for the flesh is cut through upon its point. But if the missile is not deeply seated, and lies in superficial tissue, or if it is certain that it has not crossed the line of large blood vessels or sinews, there is nothing better than to pull it out by the way it entered. BBut if the distance it has to be withdrawn is greater than that which remains to be forced through, or if it has crossed the line of blood vessels and sinews, it is more convenient to lay open the rest of its course and so draw it out. For it will be more easily got at and more safely pulled out. And in the case of one of the larger limbs, if the point has pa**ed beyond the middle, a through and through wound p317heals more easily because it can be dressed with a medicament at both ends. CBut if the missile is to be drawn back, the wound should be enlarged with a scalpel, for then the missile comes away more easily, also less inflammation is caused; for this becomes more severe if the missile itself lacerates the tissues while being withdrawn. So also when a counter opening is made, this ought to be too wide for the missile to fill as it is pa**ing out. In either case, the greatest care should be taken that no vein,29 nor one of the larger sinews, nor an artery, is cut. When any one of these is observed, it is to be caught by a blunt hook and held away from the scalpel. Than the incision has been made large enough, the missile is to be drawn out, proceeding in the same way, and taking the same care, lest that which is being extracted should injure one of those structures which I have said are to be protected. 2 The foregoing are general rules; there are some rules which apply to special missiles, and these I will at once set out. Nothing penetrates so easy into the body as an arrow, and it also becomes very deeply fixed. And this happens both because it is propelled with great force and because it is sharply pointed. Hence it is more often to be extracted through a counter opening than through the wound of entry, and especially so because it is generally furnished with barbs which lacerate more when drawn backwards than if pushed through a counter opening. BWhen a pa**age out has been laid open, the flesh ought to be stretched apart by an instrument like a Greek letter;30 next when the point has come into view, if the shaft is still attached, it is to be pushed on until the point can be seized from p319the counter opening and drawn out: if the shaft has already become detached, and only the arrowhead is within, the point should be seized by the fingers or by forceps, and so drawn out. CNor is the method of extraction different when it is preferred to withdraw the arrow by the wound of entry; the wound having been enlarged, either the shaft, if it is still attached, or, if not, the arrowhead itself, is pulled upon. When the barbs come into view, if they are short and fine, they should be nipped off on the spot by forceps, and the missile drawn out without them. If the barbs are too large and resistant for this, they must be covered by reed pens which have been split, and thus pulled out carefully so as not to tear the flesh. This is what is to be done in the case of arrows.
