46, RESECTION OF THE LATERAL CARTILAGE 



The Bayer Q,uittor Operation 



Figs. 60, 61 



Object. The cure of quittor or necrosis of the lateral 

 cartilage. 



Instruments. Elastic ligature, drawing knife, scissors, 

 razor, hoof rasp, hoof plane, craniotomy or other heavj' for- 

 ceps for the removal of the horn, artery forceps, elevator or 

 long bone chisel, right and left sage knives, curette, needle 

 holder, thread, needles, antiseptic gauze, tampons, absorb- 

 ent cotton, bandages. 



Technic. For a few hours before the operation place the 

 affected foot in a bath of creolin or other antiseptic solution, 

 after having first rasped the diseased quarter lightly and 

 having made a semicircular groove in the horn of the lateral 

 ■wall and quarter down to the horny lamina, as shown at s 

 in Fig. 6o. It is essential not to materially thin the horn on 

 the quarter with the rasp since by weakening it, it yields 

 and breaks and cannot be properly detached from the sensi- 

 tive laminae. The rasping of the wall should merely suffice 

 to remove the very hard external layer and facilitate the 

 •cutting of the groove with the hoof knife. 



The operation is performed upon the recumbent, anaes- 

 thetized animal, in such a position that the diseased carti- 

 lage of the affected foot lies upward. The operating table 

 constitutes incomparably the best means of confinement in 

 every respect. 



The hair on the coronary band is clipped or shaved and 

 the entire foot up to the fetlock joint thoroughly cleansed 

 with brush, soap, creolin or sublimate solution and 50 per 

 cent, alcohol. The fetlock and pastern are carefully 

 wrapped in a towel saturated with sublimate solution or 

 other disinfectant. The hoof should be similarly wrapped
