A Treatise on Fractures, Luxations, and Other Affections of the Bones

by P.-J. Desault

19. It was from these different considerations, that Desault modified, as I am about to mention, the apparatus for fractures of the fore-arm. To a great degree of simplicity, this apparatus unites, when thus improved, great ease to the patient, and its advantages are proven by the freedom in the different movements of the arm always experienced by the numerous patients, whom he was called to attend. The pieces of the apparatus are, 1st, Two graduated compresses, one of them of such a length as to extend from the elbow to the wrist, and the other from the wrist to the fold of the arm on the inside. They are to be formed each of a single piece of linen, folded seven or eight times on itself, in such a manner, that the lower fold may be an inch wide, while the others, laid on top of each other, gradually diminish in width to the last. The thickness of these compresses ought to be less in very fat persons, where the anterior and posterior surfaces of the arm are more convex. 2dly, A roller about four yards and a half long, and four inches wide. 3dly, Four thin but stiff wooden splints, long enough to reach, one, from the fold of the arm to the wrist, the second, from the interval or hollow space between the olecranon and the condyl to the same part, the third from the internal condyl of the humerus to the styloid process of the ulna, and the fourth from the eternal condyl to the styloid apophysis of the radius. The breadth of the two first ought to be double that of the other two, as the latter occupy a space of but half the width of that occupied by the former.

20. Every thing being arranged, the reduction is to be executed as already directed (11–13); and while the extensions are still continued, the surgeon wets with vegeto-mineral water, or some other discutient liquid, the graduated compresses, and places them on the anterior and posterior part of the fore-arm, (which must be firmly supported in a state between that of pronation and supination, 11), in such a manner, that their broadest part or base may be in immediate contact with the limb. He then secures them with a roller wet with the same liquid, the casts of which, being first fixed at the place of the fracture, descend obliquely to the wrist, and are secured at the hand by being passed between the thumb and the fore-finger. Running across the back of the hand, the roller then reascends, either by oblique or reverse turns, according to the inequalities of the fore-arm, till it reaches the elbow. Here the surgeon relinquishes the roller, giving it into the hand of an assistant, and places the four splints on the parts already mentioned (19), while the hands of a second assistant secures them, by grasping them all at their lower end, next to the wrist. The surgeon then resumes the roller, and, in order to fix the splints immoveably, descends with it along the fore-arm by circular casts, till he reaches the hand, where he finishes.

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.

24. The consolidation being completed generally in twenty-four or twenty-five days, leaves, at this time, a little stiffness in the joints, in consequence of their having remained so long without motion: the movements of pronation and supination are performed but imperfectly. Their return is facilitated and hastened by frequent exercise of the limb, as well at its junction with the os humeri, as in its own proper joints; and, in general, by the fifteenth or twentieth day from the removal of the apparatus, things are in the same state in which they stood before the fracture.
