CHAP. VII. Of the fracture of the lower Jaw.

THe lower Jaw runs into two, as it were, horns or tops: the one whereof ends sharp, and receives a tendon from the temporal muscle; the other ends blunt and round un∣der the mammillary process, and it is there implanted in a small cavity; it is joyned together in the middle of the chin by Symphysis, and is marrowy within: The Fracture, which happens thereto, is restored by putting your fingers into the Patients mouth, and pressing them on the inside and outside, that so the fractured bones put together may be smoothed and united: But if they be broken wholly athwart, so that the bones lye over each other, extension must be made on both sides on contrary parts, upwards and downwards, where∣by the bones may be composed, and joined more easily to one another: The teeth in the mean while, if they be either shaken or removed out of their sockets, must be restored to their former places, and tyed with a gold or silver wyer, or else an ordinary thred, to the next firm teeth, untill such time as they shall be fastened, and the bones pefectly knit by a Callus: To which purpose, the ordered fragments of the fractured bone shall be stayed, by

putting a splint on the outside, made of such leather as shoe-soals are made; the midst thereof being divided at the Chin, and of such length and breadth as may serve the Jaw: then you shall make ligation with a ligature two fingers broad, and of such length as shall be sufficient, divided at both the ends; and cut long-wayes in the midst thereof; that so it may engirt the chin on both sides. Then there will be four heads of such a ligature so divided at the ends; the two lower whereof being brought to the crown of the head, shall be there fastned, and sowed to the Patients night-cap. The two upper drawn athwart, shall likewise be sowed as artificially as may be, to the cap in the nape of the neck. It is a most certain sign, that the Jaw is re∣stored and well set, if the teeth fastened therein stand in their due rank and order. The Pa∣tient shall not lye down upon his broken Jaw, lest the fragments of the bones should again fall out, and cause a greater defluxion. Unless inflammation, or some other grievous symptom shall happen, it is strengthened with a Callus within twenty dayes; for that it is spongious, hollow, and full of marrow, especially in the midst thereof: yet sometimes, it heals more slowly, according as the temper of the Patient is, which takes also place in other fractured bones. The agglutina∣ting and repelling medicin, described in the former chapter, shall be used; as also others, as occasion shall offer it self. The Patient must be fed with liquid meats, which stand not in need of chewing, untill such time as the Callus shall grow hard, lest the scarce or ill-jointed fragments should fly in sunder with the labour of chewing. Therefore shall he be nourished with water-grewel, ponadoes, cullasses, barley-creams, gellies, broths, rear-egs, restaurative liquors, and other things of the like nature.
