_Of the Luxation of the _Vertebra's. In the Luxation of the _Vertebra_'s of the Neck, the Head stands to one side, and the Face is swell'd and livid, with a difficulty of Respiration. To reduce this Dislocation, the Patient is to be set upon a low Seat, an Assistant leaning on his Shoulders, to keep his Body steady, whilst the Surgeon or Operator draws his Head upward, and turns it from one side to another: Then if the Accidents or Symptoms cease, the Cure is perform'd; so that Fomentations may be apply'd to the Part; and the Patient being laid in his Bed, must take care to avoid moving his Head. When the _Vertebra_'s of the Back or Loins are luxated on the inside, a sinking of the Bone is soon perceiv'd; whereupon the Patient being laid on his Belly, the Extension is to be made with Napkins pass'd under the Arm-Pits, and upon the _Os Ileum_, whilst the Surgeon with {301} a strong Extension makes some Efforts on the Spine, endeavouring to draw back the _Vertebra_. If that be not sufficient, an Incision is to be made upon the _Apophysis Spinosa_ of the _Vertebra_; so that after having laid open this Process of the Bone, it may be taken out with a Pair of _Forceps_. Then the Wound is to be dress'd with Pledgets, a Plaister, and a Napkin, which must not be bound too close, for fear of pushing back the Spine. When the _Vertebra_ is luxated on the outside, a Prominence appears; so that to reduce this Dislocation, the Extension is to be made as before, the Patient lying in like manner upon his Belly; but in order to push back the _Vertebra_, two little Sticks trimm'd with Linnen-Cloth are to be prepar'd, and laid along the two sides of the Spine of the _Vertebra_; yet these Sticks ought to be thick enough to remain more elevated than the _Apophysis Spinosa_; and a large wooden Roller is to be often roll'd upon 'em, which by its turning backward and forward, may thrust the _Vertebra_'s inward; so that when all the _Vertebra_'s are of an equal height, the Reduction is finish'd. If the _Vertebra_'s are luxated on the side, the same Extensions are to be made, and the Prominence is to be push'd, to re-establish the _Vertebra_ in its place. _The Dressing and Bandage._ The Dressing is prepar'd by laying two thin Plates of Lead on each side of the Spinous Process of the _Vertebra_, to maintain it in its Place, and a long Bolster over 'em. The {302} proper Bandage is the _Quadriga_, which hath been before describ'd, in treating of the Fractures of the Breast-Bone. * * * * * CHAP. V. _Of the Luxation of the _Coccyx_ or Rump-Bone._ If the _Coccyx_ be sunk on the inside, it is to be rais'd with the Fore-finger of the Right-hand put into the _Anus_; and if the Luxation be on the outside, it may be gently thrust back again. An Account of its proper Dressing and Bandage hath been already given in the Fracture of the _Coccyx_. * * * * * CHAP. VI. _Of the _Bunch_._
