364 DISEASES OF THE HORSE'S FOOT 



until the whole of the diseased portion is removed, and a 

 healthy surface is felt. After-dressing must then be carried 

 out as in other cases. 



The treatment of ossified cartilage will be found under 

 treatment of side-bones, and the methods of dealing with 

 penetrated articulation and purulent arthritis are treated 

 of in Chapter XII. 



;, Surgical Shoeing in Quittor. — In the case of simple or 

 cutaneous quittor, no alteration in the shoeing is necessary. 



When the condition becomes sub-horny, however, and 

 particularly when it is situated in the region of the quarters, 

 ease is afforded to the diseased parts by removing the bear- 

 ing of the shoe in that position. 



Should there be no dependent opening at the sole, 

 then the best shoe for the purpose is an ordinary bar 

 shoe (Fig. 68), with the bearing eased under the affected 

 quarter. 



If, however, there is a dependent orifice, or one is ex- 

 pected, then it will be necessary either to leave the animal 

 unshod or to provide him with a shoe that admits of dress- 

 ing the lesion. In the latter case the most suitable shoe will 

 be found to be either a three-quarter shoe (Fig. 102) or a 

 three-quarter bar shoe (Fig. 103). Many operators, how- 

 ever, keep the animal unshod. We must say ourselves that 

 we consider a shoe useful after either of the operations 

 for removal of the cartilage, if only to assist in maintaining 

 the bandages and dressings in position. 



In this case a very useful shoe will be the three-quarter 

 bar shoe. With a little manipulation the bandages are 

 easily run under the bar portion of the shoe, and a few of 

 their turns every now and again wrapped round the bar in 

 order to keep the whole firmly in position. 



In connection with tendinous quittor, when septic matter 

 has gained the sheath of the flexor tendons, there is, for a 

 long time after healing of the fistula, a marked tendency 

 for the animal to go on his toe. To a large extent we 

 judge this to be due to slight adhesions between the two 

 tendons brought about by the growth of inflammatory
