12. In fractures we must attend to the length, breadth, thickness, and number of the compresses. The length should be that of the bandaging; the breadth, three or four fingers; thickness, three or fourfold; number so as to encircle the limb, neither more nor less;those applied for the purpose of rectifying a deformity, should be of such a length as to encircle it; the breadth and thickness being determined by the vacuity, which is not to be filled up at once. The upper bandages are two, the first of which is to be carried from the seat of the injury upwards, and the second from the seat of the injury downwards, and from below upwards; the parts about the seat of the injury being most compressed, the extremities least, and the rest in proportion. The upper bandages should take in a considerable portion of the sound parts. We must attend to the number, length, and breadth of the bandages; the number must be such as not to be inferior to what the injury requires, nor occasion compression with the splints, nor prove cumbersome, nor occasion any slipping of them, nor render them inefficient. As to length and breadth, they should be three, four, five, or six cubits in length, and as many fingers broad. The folds of the strings (selvages?) should be such as not to occasion pressure; they are to be soft and not thick; and all these things are to be proportionate to the length, breadth, and thickness of the part affected. The splints are to be smooth, even, and rounded at the extremities; somewhat less all along than the upper bandaging, and thickest at the part to which fracture inclines.
Those parts where there are tuberosities, and which are devoid of flesh, such as the ankles or fingers, we must guard from the splints which are placed over them, either by position, or by their shortness.
They are to be secured by the strings in such a manner as not to occasion pressure at first. A soft, consistent, and clean cerate should be rubbed into the folds of the bandage.
13. As to the temperature and quantity of the water used, its heat should be just such as the hand can bear, and it ought to be known that a large quantity is best for producing relaxation and attenuation, whereas a moderate quantity is best for incarnating and softening. The limit to the affusion is, to stop when the parts become swelled up, and before the swelling subsides; for the parts swell up at first, and fall afterward.
14. The object on which to (the limb?) is laid should be soft, smooth, and sloping upwards toward the protuberant parts of the body, such as the heel or hips, so that there may be no projection, nor bending inwards, nor turning aside. The canal (spout or gutter?)should rather comprehend the whole limb than the half of it, attention being paid to the injury and to whatever else appears to create inconvenience.
15. The presentation of the injured part to the physician, the extension, the arrangement, and so forth, are to be regulated according to nature. What is nature in these operations is to be determined by the accomplishment of the object which we have in view, and for this purpose we must look to the part in the state of rest, in its middle state, and to habit; in regard to the state of rest and relaxation, as in the arm, that it be in a line with the hand; and with regard to the medium between flexion and extension, that the forearm be at right angles to the arm; and with regard to habit, it should be considered that some limbs bear certain positions preferably, as, for example, the thighs extension; for in such attitudes the parts can best bear to be placed for a considerable time without a change of posture. And in the change from the state of distention, the muscles, veins, nerves, and bones, when properly arranged and secured, will preserve their relations to one another while the limb is raised or placed.
16. The extension should be most powerful when the largest and thickest bones, or when both are broken; next when the under-bone, and least of all, when the upper. When immoderate, it is injurious, except in the case of children. The limb should be a little elevated. The model by which we judge if the part be properly set is the sound part of the same name, or the part which is its pair.
17. Friction can relax, brace, incarnate, attenuate: hard braces, soft relaxes, much attenuates, and moderate thickens.
