42. RESECTION OF THE LATERAL CARTILAGE. 



The Bayer Quittor Operation. 



Plate XXXIV. 



Object. The cure of quittor or necrosis of the lateral 

 cartilage. 



Instruments. Elastic ligature, drawing knife, scissors, 

 razor, hoof ra.sp. hoof plane, craniotomy or other heavy 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, iodoform ether, iodoform gauze, 

 tampons, absorbent 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 /z^^/*/}/ 

 and make a semicircular groove in the horn of the lateral 

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

 in Fig. I, Plate XXXIV. It is essential to not materially 

 thin the horn on the quarter with the rasp since by weaken- 

 ing it, it yields and breaks and cannot be properly detached 

 from the senitive laminae. 



The operation is peformed upon the recumbent, anaes- 

 thetized animal, in such a position that the diseased cartilage 

 of the affected foot lies upward. The operating table consti- 

 tutes incomparably the best means of confinement in every 

 respect. After the application of the elastic ligature in the 

 metacarpal or metatarsal region the groove in the horn is 

 deepened with the drawing knife down to the sensitive 

 laminae without injuring them. The groove must be so 

 located that it extends beyond the anterior and posterior 

 borders of the lateral cartilage, and downwards to within i 

 or 2 cm. of the margin of the os pedis and approximately 

 perpendicular to the surface of the horn wall so that it will 

 form a secure support for the dressing to be later applied. 

 The hair on the coronary band is clipped or shaved and the
