62. Extension is now made in the mode already pointed out (29 and 30), and then the application of the apparatus is begun, for which the surgeon must be situated on the external side of the fractured thigh, while an aid, placed on the other side, gives him assistance.
1st, On the thigh, next to the skin, are first applied the long and circular compresses, accurately spread out so as to have no wrinkles in them, and previously wet with vegeto-mineral water. Around it are then applied, in succession and from below upwards, each strip of the bandage (EE) moderately tight.
2dly, The lower end of the leg is now covered with a thick compress, intended to prevent the impression of the roller (L), which is fixed in such a manner, that its middle is first laid on the tendo Achillis, a little above the heel, while its two ends, crossing each other on the upper part of the foot, are carried on each side to its sole, where crossing again, they are then laid down till the close of the application of the apparatus.
3dly, Along the thigh are placed laterally two bolsters, which, from their thickness being easily increased or diminished in consequence of the moveable nature of the chaff, mould themselves to the inequalities of the limb.
4thly, Around the two lateral splints, the surgeon and his assistant roll, each on his respective side, the two edges of the junk-cloth, so that both splints, by being accurately applied on the bolsters, may make a uniform compression on the whole part.
5thly, The third bolster (d d d d) is then applied on the anterior part of the limb, and over it the splint (CC).
6. The bits of tape passed under the apparatus to the number of four for the thigh, and three for the leg, are tied in succession on the external splint, lest the knots, should they correspond to the thigh, might, by their contact, prove troublesome. That one next to the fracture is tied first, and they are all drawn as tight as the patient can bear them without uneasiness.
7. The body-bandage is now fixed on the pelvis, in such a manner, as to secure laterally the external splint, and is itself retained by the sub-femoral bandage (H), that is, the bandage passing under the thigh.
8. A thick compress placed beneath the tuberosity of the ischium, serves as a cushion or bolster to protect the part from the pressure of the roller (g g) which, being passed first under the apparatus, and drawn afterwards obliquely from within outwards, and from above downwards, takes its points of bearing or action, in one part, on the tuberosity of the ischium, and in the other, on the upper end of the external splint, and is tied in the fold or hollow of the groin.
