The essentials of bandaging /

by Berkeley Hill

4. Strapping plaster, and some ends of bandage.

Step 1. The limb is washed and dried, and the short pad fitted to the foot-piece, which is furnished with some hooks at its lower surface, where ends of bandage or tape can be fastened, for fixing it to the wire frame. The frame is next prepared by passing strips of bandage across it from side to side at short intervals, to make a support on which the limb is laid; if there is no wound, a soft pad may be put on the frame first, but if one be present, the limb should rest immediately on the strips of bandage, which can be changed whenever soiled, and replaced by clean ones without disturbing the limb. These strips should be tacked on with a needle and thread, that, when the limb is placed on the apparatus, they can be shortened or lengthened till the leg bears evenly on them (see fig. 53).

Step 2. The foot-piece is adjusted and fastened to the foot by straps of plaster carried round it and up each side of the leg, as was done for the stirrup extension in the “long splint” (p. [76]).

Step 3. The limb is next placed in the cradle formed for it, to the lower end of which the foot-piece is tied securely; the ropes are rove through the pulleys and tightened till the limb swings easily. The point of attachment of the ropes must not be just above the limb, but beyond it, that the leg may be drawn away from the body along its own axis. The weight of the body makes counter-extension sufficient to remove all shortening in a few days. The relief from the constraint attending the absolute immobility of the long splint, renders this apparatus a particularly easy one for the patient; and union is found to take place without any shortening of the limb. Where there is no wound, the limb and frame may be kept together by a roller bandage carried round them from the toes to the knee, after the limb has been adjusted in the splint.

Continuous Extension in the straight position is employed for fractures of the femur and in hip-disease. It is procured as follows. A stirrup is fastened to the leg in the way described at page [76]; to this a cord and weight are attached below the sole of the foot, and passed over a pulley fixed to a tripod frame (fig. 54), or any convenient object below the bed, in a line with the axis of the limb. The weight should balance the contraction of the muscles, and usually varies between 2 and 6 lbs. A perineal band fastened behind the patient’s head keeps the body from following the limb. The weight may be a common scale weight, or a bag with a hole at the bottom closed by a string, and filled with shot or sand, or a can with a tap at the bottom filled with water: these arrangements allow increase or lessening of the weight, without slackening the cord and moving the limb. This apparatus requires no bandages, which are so difficult to keep clean in children, and exerts a very even and continuous strain on the limb.

The perineal band may be often dispensed with, by laying the patient on a flat mattress and raising the foot of the bedstead a few inches higher than the head; the body then sinks towards the head of the bed and resists the extension of the leg.
