RESECTION OF THE LATERAL CARTILAGE. 191 



granulations. By means of an incision through the carti- 

 lage parallel to the long axis of the foot, divide it into 

 anterior and posterior halves and extirpate the latter first 

 by dissecting it out on the inner side from the parachondrial 

 tissue with the double-edged sage knife. The point of the 

 knife must be constantly directed against the cartilage. 

 Since the inner surface of the anterior half of the cartilage 

 lies immediately against the capsular ligament of the corono- 

 pedal articulation the latter should be sharply extended by 

 which means the capsular ligament is-drawn away from the 

 cartilage during its extirpation. The anterior half of the 

 cartilage, k, is then removed in the same way, except with 

 the greatest possible care to avoid puncturing the corono- 

 pedal articulation. Remnants of cartilage at its juncture 

 with the retrossal process of the os pedis, and granula- 

 tions are to be removed with the curette. Cut away with 

 the scissors and knife any remnants of cartilage adherent 

 to the flap, /, thin if necessary the entire flap and excise the 

 fistulous openings, g. After thorough disinfection of the 

 entire field of operation sprinkle it over thickly with 

 powdered iodoform and return the flap to its former position 

 and retain it there by a sufficient number of interrupted 

 sutures as shown in Fig. 2. The first sutures to be applied 

 should be at the border line between the skin and coronary 

 band so as to insure accurate apposition at this point. 

 Sprinkle the wound surface with iodoform and cover the 

 parts over with iodoform gauze and tampons which rest 

 firmly upon the perpendicular wall of horn. Finally invest 

 the hoof and pastern up to the fetlock joint with an abund- 

 ance of oakum saturated with i-iooo sublimate solution 

 and lay a heavy tar bandage over it, the tvirns of which 

 must completely invest it at every point and render the 

 dressing impermeable to moisture. Remove the elastic liga- 

 ture. If the animal is free from fever, feels and eats well, 

 the bandage, is left in position from 12 to 14 days. Healing 

 by first intention.
