OF FRACTURES. THE FIFTEENTH BOOKE. (Book 15)
CHAP. I. What a Fracture is, and what the differences thereof are.
A Fracture, in Galens opinion, is the solution of continuitie in a * 1.1 bone, which by the Greeks is called Catagma. There are many sorts of hurting or offending the bones: as the drawing them a-sunder, luxation, or putting them out of joynt; their unnaturall growing together, their cutting or dividing a-sunder; contusion, abscesse, putrefaction, rottennesse, laying bare the periostium being violated or lost; and lastly, that whereof we now treate, a Fracture. Again, the varieties of Fractures are almost infinite. For one is complete and perfect, another imperfect; one runnes long-wise, another transverse, another oblique; one while it is broken into great peeces, another while into little and small scales, which have eyther a blunt, or else a sharpe end, and pricke the adjacent bo∣dies of the muscles, nerves, veines or arteries. It somtimes happens, that the bone is not broken into splinters, that is, long-wayes, but together, and at once into two peeces overthwart, which Fracture is called Raphanedon, that is, after the maner of * 1.2 a Raddish.
A Fracture is made Caryedon, or like a nut, when as the bone flyes into many * 1.3 small peeces, severed each from other, as when a Nut is broken with a hammer or mallet upon an Anvile: Which fracture is also termed Alphitidon, by reason of the resemblance it hath to meale or floure; and such is often seene in fractures made by bullets, shot out of guns and such fiery engines. Contrary to these are those fra∣ctures which are called Schidacidon, as rent into splinters, or after the manner of * 1.4 a boord or peece of timber, that is, right-downe, and alongst the bone: and these fractures are eyther apparent to the eye, or else not apparent, and therefore called Capillarie, being so small, as that they cannot be perceived by the eye, unlesse you put inke upon them, and then shave them with your Scrapers. Sometimes the bone is only pressed downe by the stroke, sometimes on the contrarie it flyes up, as if it were vaulted. They call it attrition, when the bone is broken into many small fragments, and as it were scales or chips. The fragments of fractured bones are somtimes smooth and polished, otherwhiles unequall, and as it were sharpe and rough with little teeth, or prickes. Some fractures touch onely the surface of the bone, fetching off only a scale; othersome change not the site of fractured bones, but only cleaves them length-waies, without the plucking away of any fragment; othersome penetrate even to their marrow.
Furthermore some Fractures are simple and alone by themselves; othersome are accompanied with a troop of other affects and symptomes; as a wound, haemorrha∣gye, inflammation, gangrene, and the like. Hereunto you may also adde the diffe∣rences
