702 OPERATIONS ON THE FOOT. 



of this affection in its simple form. An operation, often recom- 

 mended, has been that of neurotomy, upon the posterior branches 

 of the plantar nerves, repeated at intervals of at least fifteen days, 

 in order to remove the lameness wholly, without entirely depriv- 

 ing the foot of the sensibility of feeling. Berger, Brauell, Bou- 

 ley. Gross, Mandel, and others, have obtained real success by it; 

 but it is attended with serious dangers ; at any rate the benefit is 

 not of long duration, or about one year. The animal then stumbles 

 more readily, and is more exposed to traumatic lesions, etc., and 

 it is probable from this cause that double neurotomy is seen to be 

 followed by softening of the deep parts of the foot, suppuration, 

 sloughing of the foot, whUe the animal has previously shown no 

 signs of pain. Consequently, neurotomy is an operation which 

 finds its appUcation only in peculiar and exceptional cases, and 

 animals thus operated upon remain fit for light work only. 



QUITTOE. 



Synonyms. — Fesselgeschwur, German ; giarda, Italian ; gialarrs, 

 Spanish ; javart, French. 



A name of unknown etymology, by which old hippiatrics desig- 

 nate various affections of the inferior regions of the legs of the 

 horse, donkey and mule, and even of bovines. These possess the 

 common character of a degeneration of a portion of the tissues, 

 that is expelled by the efforts of nature under the form of a slough 

 {iourbillon). There is a softening of the mortified structures, 

 and an elimination by suppuration. In several old works, these 

 sloughs are called quittors (Javars), and this name has been ex- 

 tended to the disease itself. 



This name having been preserved by use, notwithstanding the 

 efforts of Yatel in opposition, we shall also employ it, and with 

 Girard, recognize : 1st. The s*mpZe or CMtoneows quittor, which 

 is only the furuncle which occurs in the thickness of the dermoid 

 structure nearest to the coronary band. 2d. The tendinous quit- 

 tor, which greatly resembles the felon of man, where a portion of 

 the sub-cutaneous cellular tissue, and of a tendon sloughs out. 

 3d. The sub-horny quittor, the furuncle of the cutidura of the 

 coronary band itself, the slough involving the superior portion of 

 laminated tissue. 4th. The cartilaginous quittor, or the limited 

 caries of the lateral fibro-cartUage of the os pedis, and which old 

 writers compounded with the horny quittor. We might join to
