328 THE PRACTICE OF VETERINARY MEDICINE. 



QUITTOR. 



Definition. — A fistulous opening at the upper portion of 

 the hoof, extending down between the sensitive and the 

 insensitiv^e lamina', and sometimes penetrating deeply and 

 involving the bone. It is a serious condition, and especially 

 so when occurring in an animal having a heavy, strong hoof. 



Causes. — It occurs as a result of neglected caulks, pricks,, 

 etc., and is more especially liable to follow punctured 

 M-ounds in the region of the frog. Suppurating corns may 

 also produce quittor. Suppuration occurring in the foot^ 

 from any cause whatever, may result in quittor, for the 

 reason that the pus, being unable to escape, extends in 

 various directions, destroying the tissues in its course, in- 

 creases in quantity, until, finally reaching the head of the 

 hoof, and being no longer confined by the horny wall, it 

 bursts forth, making an outlet for itself at the coronet, when 

 it becomes known as a quittor. 



Symptoms. — Usually the first symptom to attract atten- 

 tion is lameness, which is generally well marked. On 

 examining the parts, a hard swelling is discovered at the 

 head of the hoof; this swelling in a day or two becomes soft, 

 and finally a discharge of pus takes place ; but a sinus 

 remains, and the wound shows no disposition to heal. 

 Sometimes the irritation extends and involves the whole 

 coronary substance, and perhaps a half-dozen or more 

 openings may be present at one time : such a case is very 

 serious. 



Treatiaent. — Quittor once well established is veiy diflftcult 

 to treat successfully, and in all cases the treatment is tedious, 

 and occupies a long time. Nothing short of the most ener- 

 getic treatment will prove successful. The original cause of 

 the trouble should be ascertained, if possible. If taken in 

 time, remove the shoes, and cut down the wall immediately
