If the Fracture be only on one side, a Bolster sow'd to a piece of Paste-board is to be laid upon the flat side of the Jaw, both being of the Figure and Size of the Jaw it self. The Bandage of this Fracture is call'd _Chevestre_, i.e. _a Cord or Bridle_, by the _French_ Surgeons, and is made by taking a Band roll'd with one Head or End, three Ells long, and two Fingers broad; the Application of it is begun with making a Circumvolution round about the Head in passing over the Fore-head; then the Band is let down under the Chin, and carry'd up again upon the Cheek, near the lesser Corner of the Eye in passing over the Fracture; afterward it is rais'd up to the Head, and brought down again under the Chin, {275} to form a Roller or Bolster upon the Fracture: Thus three or four Circumvolutions and Rollers being made upon the Fracture, the Band is let down under the Chin, to stay and strengthen its several Turns, and is terminated round the Head, in passing over the Fore-head. If the Jaw be fractur'd on both sides, it wou'd be requisite to apply thereto a Bolster and Paste-board, perforated at the Chin, and of the Figure of the entire Jaw; the Bandage which we have even now describ'd, may be also prepar'd in making Rollers on both sides of the Jaw: Or else the double _Chevestre_ may be made with a Band of five Ells long, and two Fingers broad, roll'd up with two Balls, that is to say, with the two Ends. The Application of this Band is begun under the Chin, from whence it is carry'd up over the Cheek, cross'd upon the top of the Head, and brought down behind the Head, where it is cross'd again; then it is let down under the Chin, cross'd there, and carry'd up over the Fracture; afterward the Band being pass'd three or four times over the same turns, in making Rollers upon the Jaws, is turn'd upon the Chin, and stay'd upon the Forehead round about the Head. * * * * * {276} CHAP. III. _Of the Fracture of the _Clavicle_._ The Patient is to be set in a Chair, and his Arm is to be drawn backward, whilst an Assistant thrusts his Shoulder forward: In the mean time the Operator sets the Bones again in their place, by thrusting the Protuberances, and drawing out the sunk Bone. Or else a Tennis-Ball may be taken, and put under the Patient's Arm-Pit, whose Elbow is then to be press'd against his Ribs, whilst the Surgeon reduceth the Fracture. Otherwise, the Patient may be laid upon his Back, putting a Convex Body under both his Shoulders, as a Bowl, or large wooden Porrenger; and then the Shoulders may be prest, to raise up the two ends of the Bones, which the Surgeon must take care to reduce. _The Dressing and Bandage._
