Dislocation of the wrist is reduced by gentle extension from the hand and counter-extension from the forearm, and dislocation of the fingers by a similar manipulation.

After so full a consideration of the surgical injuries of the head, trunk and upper extremities, we are somewhat surprised to find Gilbert's discussion of the similar injuries of the lower extremities condensed into a single very moderate chapter entitled "De vulneribus cruris et tybie" (f. 358a b).

In this, Gilbert, emphasizing the importance of wounds of the patella and knee-joint and the necessity for their careful treatment, also declares that wounds of both the leg and thigh within three inches of the joints, or in the fleshy portion of the thigh ubi organum est (?), involve considerable danger. He then speaks of a blackish, hard and very painful tumor of the thigh, which, when it ascends the thigh (ad superiora ascendit) is mortal, but if it descends is less dangerous. Separation of the sacrum (vertebrum) from the ilium (scia), either by accident or from the corrosion of humors, leaves the patient permanently lame, though suitable fomentations and inunctions may produce some improvement. Sprains of the ankle are to be treated by placing the joint immediately in very cold water ad repercussionem spiritus et sanguinis, and the joint is to be kept thus refrigerated until it even becomes numb (stupefactionem); after which stupes of salt water and urine are to be applied, followed by a plaster of galbanum, opoponax, the apostolicon, etc.

Fractures of the femur are to be treated like those of the humerus, except that the ends of the fractured bone are to be separated by the space of an inch, and a bandage six fingers in width carefully applied. Such fractures within three inches of the hip or knee-joint are regarded as specially dangerous.

Dislocations of the ankle, after reduction of proper manipulation, should be bound with suitable splints. If of a less severe character, the dislocation may be dressed with stupes of canabina (Indian hemp), urine and salt water, which greatly mitigate the pain and swelling. Afterwards the joint should be strapped for four or five inches above the ankle with plaster, ut prohibeatur fluxus.

It should be said that the brevity of this chapter of Gilbert is modeled after the manner of Roger of Parma, who refers the treatment of injuries of the lower extremities very largely to that of similar injuries of the upper, merely adding thereto such explanations as may be demanded by the differences of location and function of the members involved. Thus in his discussion of dislocation of the femur Roger says:

Si crus a coxa sit disjunctum, eadem sit cura quam et in disjuncturam brachii et cubiti diximus, etc.

The general subject of fistulae is treated at considerable length on folio 205b, and fistula lachrymalis and fistulae of the jaw receive special attention in their appropriate places. As a rule, the fistula is dilated by a tent of alder-pith, mandragora, briony or gentian, the lining membrane destroyed by an ointment of quick-lime or even the actual cautery, and the wound then dressed with egg-albumen followed by the unguentum viride. Necrosed bone is to be removed, if necessary, by deep incisions, and decayed teeth are to be extracted.

The elongated uvula is to be snipped off, and abscesses of the tonsils opened tout comme chez nous.
