CHAP. XXVII. Of a DISLOCATION of the HEEL-BONE.

I. IT is called in Greek, 〈 in non-Latin alphabet 〉〈 in non-Latin alphabet 〉. in Latin, Dis∣locatio vel Luxatio, Ossis Calcis vel Calcanei; and in English, A Dislocation or Luxation of the Heel, or Bone of the Heel.

II. 〈 in non-Latin alphabet 〉〈 in non-Latin alphabet 〉, Os Calcis vel Calcanei, The Heel-bone is the second Bone of the Tarsus, and the greatest of the seven Bones which compleat the instep: it lyes under the Talus, with which in its upper side it is articulated, being joined thereto by Cartila∣ginous Ligaments.

III. In its fore-end, it is re∣ceived by the Os Cubiforme: Be∣hind it receives the great Tendon called Nervus Hectoreus, or that great Chord, which is compo∣sed of the Tendons of the three Muscles which extend the Foot.

IV. On its inside it has a large Sinus or Cavity, by which the Ten∣dons and larger Vessels descend to the under side of the Foot: and on its outside, it is uneven with several Protuberances, for the firmer Connexion of the Liga∣ments and Tendons.

V. The Causes. The Heel is for the most part luxated from the Ankle, by leaping or falling from an high place, the Patient falling upon the Heel; sometimes also it has been dislocated in Dancing.

VI. The Signs. It is easily

known by the great Pain, depra∣ved figure of the Part, and hurt of the Action.

VII. The Heel-bone lying under the Ankle, is often dislocated, but more especially forward or back∣ward: very seldom to the Sides, whether inward or outward.

VIII. The Prognosticks. A Luxation of the Heel is very dan∣gerous, because the Arteries, Veins, and greater Nerves which it re∣ceives, and also the Tendon con∣joined with it, are easily drawn into consent; whence may arise acute Fevers, Tremblings, Ra∣vings, Convulsions, Swoonings, and many other pernicious Sym∣ptoms.

IX. The Cure. It is reduced into its pristin condition by a light Extension, putting with your Fingers the Bone into its right place.

X. When it is reduced, it must be so bound up, that the Humors abounding may be driven from it to other Parts; and the Sick must so long rest himself, till the Joint is fully confirmed.

XI. If there is a great Weak∣ness in the Part, or a Flux of Hu∣mors, Astringent and Strength∣ning Topicks are to be applied, renewed, and continued so long as you see need shall require.

XII. And the abundance of Hu∣mors flowing to the Part are to be diverted, by a daily and constant giving of proper Emeticks and Ca∣tharticks, according as the Strength of the Sick will permit; such are Tartar Emeticum, Infusion of Crocus Metallorum, Wine and Vinegar of Squills, for Vomiting: and Syrupus Catharticus, Pulvis Catharticus, Pulvis Cornachini, and Our Family or Panchyma∣goge Pills, for Purging, with other things of like-nature.
