CHAP. XXXV. Of the dislocation of the Wrist.
* 1.1WEe understand by the Wrist, a certain bony body, consisting of a composure of eight bones knit to the whole Cubit by Diarthrosis: For the Wrist considered wholly in its self, is knit and articulated with the Ell and Wand: with that, against the little finger; with this, against the thumb: for thus as it were by two connexions the joint is made more firm: Yet may it be dislocated inwardly, outwardly, and towards the sides. We say it is luxated inwardly when the hand stands up∣wards, but outwardly, when it is crookt in and cannot be extended: But if it chance to be disloca∣ted sidewayes, it stands awry either towards the little finger, or else towards the thumb, as the luxa∣tion befalls to this or that side. The cause hereof may seem to depend upon the different dearticu∣lation of the ell and wand with the hand or wrist: For the Wand, which is articulated on the lower part with the wrist at the thumb, by its upper part, whilest it receives the outward swelling or con∣dyle of the Ell in its cavity, performs the circular motions of the hands: But the Cubit or Ell, which in like sort is connected on the lower part by Diarthrosis at the little finger with the Wrist, being articulated on the upper part with the shoulder-bone, bends and extends, or stretches forth the hand. There is one way to restore the formerly mentioned dislocations: The arm on one side and the hand on another must be extended upon a hard resisting and smooth place, so that it may lye flat; and you must have a care that the part whence the dislocated bone fell, be the lower in its site and place, and the part whither it is gone, the higher: Then to conclude, the prominencies of the bones must be pressed down by the hand of the Surgeon, untill by the force of compression and site the luxated bones be thrust and forced into their places and cavities.
