Is made with a Band five Ells long, and two Fingers broad, roll'd with one Ball: The Application of it is begun with a Circumvolution at the lower part of the _Humerus_, it is pass'd over the Fold of the Arm; a Circumvolution is also form'd in the upper-part of the Elbow, and the Figure of KY in its Fold. Afterward the Rollers are continu'd upon the Elbow, and the KY's in the inside of the Arm, till the Elbow be entirely cover'd: The Band is likewise carry'd up to the top of the Arm with Rollers, and stay'd round about the Body. The Patient must be oblig'd to keep his Bed, or else his Arm may be put in a Scarf, after the same manner as in the Fracture of the Arm. * * * * * {308} CHAP. XI. _Of the Luxation of the Wrist._ If the Luxation be Internal, the Hand is turn'd back to the outside, so that for the Reduction thereof, it wou'd be requisite to cause the back of the Hand to be laid upon a Table, and the Extension to be made by drawing the Elbow and Hand, whilst the Surgeon takes care to press the Prominence. If the Luxation be External, the Hand is bended on the inside; so that to reduce it, the inside of the Hand is to be laid upon a Table, and the Surgeon is to press it after the Extension. If the Luxation be on the sides, the Hand is turn'd to one side; so that the Extension must be made, and the Hand turn'd on the side opposite to the Luxation. But the Fingers are usually drawn one after another, to the end that the Tendons may be set again in their Place. The eight Bones of the _Carpus_ may be in like manner dislocated both on the inside and without; and to set 'em right, the Hand is to be laid upon a Table, and the Extension to be made, so as to press the Protuberances on the inside, if the Luxation be internal, and on the outside if it be external. {309} _The Bandage_ Is prepar'd with a Band six Ells long, and two Fingers broad; so that three Circumvolutions may be made upon the Luxation; as also divers Rollers in passing thro' the inside of the Hand between the Thumb and the Forefinger, and in forming the Figure of KY upon the Thumb, after having made many Rollers upon the Wrist. Two Pieces of Paste-board are also to be laid on the sides of the Wrist, which are bound with the same Band in making Rollers; and the Hand is to be trimm'd with a Linnen-Ball, to keep the Fingers in their mean Situation. Then the Band is to be pass'd above, to strengthen it, and carry'd up with Rollers along the whole length of the Elbow, to be stay'd below the same Elbow. * * * * * CHAP. XII. _Of the Luxation of the Fingers._ If the Fingers be luxated, it is necessary to make an Extension to reduce 'em, and afterward to use the following _Bandage._
