A Bolster and Paste-board are to be laid upon the _Sternum_, almost of the same Figure with the Part; and the Bandage is to be prepar'd with a Napkin supported with a Scapulary. Or else the Bandage call'd _Quadriga_ may be made with a Band roll'd with two Heads, five Ells long, and four Fingers broad: The Application of this Band is begun under the Arm-pit; the Figure of KY is form'd under the Shoulder; the Band is carry'd downward with the two Balls, once before, and the other behind; it is pass'd under the other Arm-hole; the Heads are cross'd upon the Shoulder, and it is brought down backward and forward, forming a KY before and behind. Afterward the Bank is roll'd about the Breast in making Rollers or Bolsters; these Rollers are continu'd till the Band be terminated; and it is stay'd by a Cirumvolution round the Breast. * * * * * CHAP. VII. _Of the Fracture of the _Vertebra_'s._ The _Apophyses_ of the _Vertebra's_ are commonly broken, and their Bodies but seldom: It may be known that the Body of the _Vertebra_ of the Neck and Back is fractur'd by the Palsie of the Arm, accompany'd with the loss of Feeling; by the suppression of Urine; {282} and by the Palsie of the _Sphincter_ of the _Anus_; so that the Excrements cannot be any longer retain'd. If these Symptoms appear, it may well be conceiv'd that the Marrow is compress'd, and prickt with Points; for the removing of which, it is necessary to make an Incision upon the Body of the _Vertebra_ in the fractur'd Place. If the _Apophyses Spinosæ_ are only fractur'd, these Accidents will not happen, only some Pain will be felt: To reduce 'em, the Patient is to be laid upon his Belly, and the Surgeon must use his utmost endeavours to raise up the Bone again, and to set it in its Natural Situation. _The Dressing and Bandage._ If the _Apophysis Spinosa_ were fractur'd, it wou'd be requisite to apply to each side of it a small long Bolster, which is to be cover'd with a Paste-board of the same Figure with the Bolster; another Bolster lying upon each Paste-board. The Bandage is to be made with a Napkin sustain'd by its Scapulary; or else the _Quadriga_ may be prepar'd, according to the manner we have already describ'd in the Fracture of the _Sternum_. * * * * * {283} CHAP.
