If the Luxation be in the first Articulation or Joint, the Bandage _Spica_ is to be apply'd, being made of a Band roll'd with one Head, an {310} Ell long, and an Inch broad: It is begun with Circumvolutions round about the Wrist, and brought over the Luxation in passing between the Fingers. These Circumvolutions are also continu'd to form a _Spica_ upon the Luxation; and the Band is stay'd at the Wrist. If all the first _Phalanges_ were dislocated, it wou'd be requisite to make as many upon every _Phalanx_, and with the same Band: This sort of Bandage is call'd the _Demi-Gantlet_. * * * * * CHAP. XIII. _Of the Luxation of the Thigh._ The Luxation which most commonly happens in this Part, is the Internal; so that a Protuberance appears on the Hole of the _Os Pubis_; the indispos'd Leg is longer than the other, and the Knee and Foot turn outward; neither can the Thigh be any longer bended, nor drawn near the other. If the Luxation be External, the Leg becomes shorter than the other, the Knee and Foot turning inward, and the Heel to the outside. When the Luxation is on the fore-part, a Tumour ariseth in the Groin, so that the Patient cannot draw this Thigh toward the other, nor bend the Leg; his Body resting only upon the Heel. {311} If the Luxation be Posterior, a Tumour is felt in the Buttocks with great Pain, and the Legg is shorter than it ought to be: There also appears a sinking in the Groin, the Leg is lifted off from the Ground, and the hurt Person is apt to fall backward. To reduce the Internal Luxation, the Patient is to be laid with his Back upon a Table, to which is fixt a thick Wooden Pin, about a Foot long, which is to be set between his Thighs, to detain his Body when his Legs are drawn down; then a Strap is to be pass'd above the joynt of the Thigh, to draw the _Ischion_ upward; and the Thigh is to be drawn down with another Strap fasten'd above the Knee: In the mean while the Surgeon thrusts the Thigh upward, to cause it to re-enter its Cavity, the Straps being somewhat loosen'd in the time of the Reduction to facilitate the Operation. To reduce the External Luxation, the Patient is to be laid upon his Belly; and the drawing to be perform'd after the same manner as we have even now shewn, whilst the Thigh is thrust from the outside inward, to cause the bone to re-enter its Cavity. In reducing the Anterior Luxation, the hurt Person is to be laid upon the side opposite to the Luxation, and Extensions are to be made, by drawing both upward and down-ward, as before: Then the Head of the Bone is to be forc'd, by the means of a Ball thrust strongly with the Knee, in drawing the luxated leg toward the other. {312}
