EXCISION OP LATERAL CARTILAGE IN QUITTOR. 1073 



This avoids the necessity of stripping the wall, which is very painful. 

 The parts are then soaked in sublimate, and if operation should 

 not immediately follow, the hoof may be surrounded with wood- 

 wool, and kept wet with sublimate solution for twenty -four hours. 



The horse is cast and anaesthetised, and the diseased foot may 

 be attached to the cannon bone of the diagonal upper limb or removed 

 from the hobble and held extended. An Esmarch's bandage is 

 then applied from the- coronet to the knee, the dressing removed, 

 and the foot rinsed with sublimate solution. 



An incision is next made with a special curved knife (see Fig. 569),

following the lower border of the coronary band, and corresponding 

 to the size of the cartilage : any horn which has been left at this 

 point is removed. The object of this incision is to separate the 

 coronary band from the sensitive lamina?, with which it is continuous. 

 The incision should not at this stage extend beyond the inner surface 

 of the coronary band, and particular care must be taken not to divide 

 the band, especially near the bulb of the heel. 



The edge of the coronary band is now drawn upwards with one 

 or more retractors, and the double-edged knife passed cautiously 

 in a perpendicular direction between the coronary band and the 

 face of the cartilage so as to separate the two structures. Starting 

 in the centre of the cartilage the operator first exposes the posterior,
