There is, in the application of this bandage, an essential precaution to be observed; which is, that as each turn of the roller passes over the graduated compresses, the surgeon ought to press on these compresses with the thumb and fore-finger of his left hand, in order that the muscles, by being forced into the interstice between the radius and ulna may prevent their approximation, which would produce an inequality in the compression made by the apparatus. 21. After the application of the apparatus, if the patient be obliged to keep his bed, the fore-arm is to be extended on a pillow, taking care to keep it always half-bent, and guarded by hoops from the weight of the bed-clothes. But if the fracture be not a compound one, and if the fall has done no injury to the system in general, it is unnecessary to confine the patient to a position wearisome, and oftentimes insupportable to many persons. Then the limb is to be suspended in a sling, which is always sufficient to support it, without having recourse to the kind of hollow case recommended by Bell, which is seldom at hand, and the use of which must be extremely inconvenient. 22. The subsequent treatment to be adopted in such fractures is simple and easy: to wet the apparatus daily, for a few days, with vegeto-mineral water, to obviate, by proper means, the accidents that may occur; to renew the application of the roller at the end of eight days, or perhaps later, according to the degree of its relaxation; to repeat this application two or three times during the course of the treatment; to allow, at first, but light diet, which may be afterwards more solid, and given in larger quantity, and to admit finally of a return to the patient’s usual mode of living: such was, in cases of fracture, the practice of Desault, which was always attended with happy effects. 23. Sometimes a considerable swelling occurs, after the application of the bandage, on the back and face of the hand; small blisters appear between the fingers; the patient experiences sharp pains along the fore-arm; and other small blisters rise on its surface. It is then necessary to remove the apparatus, to open the blisters by pricking the cuticle, and dress the part with cerate spread on linen rags; replace the apparatus, making it less tight than before, taking care to renew it every day, till the excoriation be entirely gone. This accident, of no great consequence in itself, has frequently occurred to Desault, although the rollers were applied at first with but a moderate degree of tightness.
