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

by P.-J. Desault

53. Between these two extremes (50 and 51), it remains to choose a middle course, and that position will be best, in which the fore-arm shall be, so to speak, in a state between semi-flexion and extension. By this the fragments, being brought into perfect contact, will experience no obstacle to a reunion, which will be therefore both speedy and uniform.

54. But it would be useless to place the limb in a proper position, if no means were made use of to retain it there. Being immediately submitted to the action and influence of a multitude of causes, it will lose its position, and the work of nature being interrupted, the consolidation will be retarded.

Hence appears, both the necessity of placing a solid body, as Desault did, before the whole of the limb, to prevent its flexion, and the insufficiency of the apparatus proposed by Duverney and others, who directed to lay a thick compress on the fracture, to surround the elbow then by a circular one, to secure the whole by a kind of figure of 8 bandage, similar to that used in blood-letting, and, finally, to place the limb on a pillow, without further precaution.

55. Position alone evidently acts only on the lower fragment, which it directs towards the upper one. But it is also necessary to draw the upper fragment towards the lower one, and fix it there, and this is certainly the most difficult point; because, the triceps muscle having a constant tendency to contract, opposes its action to the approximation of the fragments, and indeed prevents it, if, as in the means usually proposed and adopted, the pieces of the bandage glide easily over each other.

56. These considerations determined Desault to search for some means which, being more efficacious than those already in use, might better fulfil the indications of the fracture. He accordingly invented the apparatus which we are about to describe; some ideas of this apparatus are indeed borrowed from other bandages. The success which attended the use of it at the Hotel-Dieu, will, without doubt, introduce it generally into rational practice, where the insufficiency of the old forms of apparatus is acknowledged.

1st, The fore-arm being placed in the position already directed (53), two assistants retain it in that situation, while the surgeon applies on its lower part the end of a roller five or six yards long, and about four inches wide, wet with some discutient liquid, making with it, at first, one or two circular turns to fasten it. Then ascending from below upwards, he covers the whole of the fore-arm with oblique and reverse turns moderately tight.

2dly, Having arrived at the joint, he stops, and makes an assistant draw the skin of the elbow upwards, lest, being loosened and wrinkled by means of the extension, it might get between the fragments, and create an impediment to their reunion. Then, taking hold of the olecranon, he draws it down towards the ulna, and passes behind it, as a substitute for his fingers which have hitherto kept it firmly fixed, a cast of the roller, which he brings from the anterior part of the fore-arm above the elbow. Descending again with the roller along the external side of the arm, and returning across the anterior part, he pursues again the same course, so as to make the casts of the roller lie on each other, and surround the elbow like a kind of figure of 8.

3dly, The surgeon proceeds now by oblique turns, to the upper part of the arm, where he fixes the roller, by a circular turn, and gives it into the hand of an assistant. He next applies along the arm and fore-arm, a splint very strong, but a little bent at the place which corresponds to the joint, in order to prevent too great an extension of the limb: then, resuming the roller, he employs it, in a descending direction, to secure the splint.

4thly, The apparatus being applied, the limb is placed on a pillow, so as to be equally supported throughout its length, and is protected by hoops from the weight of the bed-clothes.
