172 LAMENESS OF THE HORSE 



poured on a layer of cotton, and this is confined in contact with 

 the inflamed parts by means of a bandage. 



Where normal resistance to infection obtains, the subject usu- 

 ally suffers no suppurative disturbance when the surface struc- 

 tures are not broken; and daily applications of the antiseptic 

 lotion above referred to stimulates complete resolution. This 

 may be expected in from four to ten days depending upon the 

 extent of the injury. 



If a calk wound has been inflicted, the adjoining surface struc- 

 tures are freed of hair and the parts cleansed in the usual man- 

 ner, (which in wounds recently inflicted, should be done without 

 employing quantities of water) and after painting the wound 

 surface with tincture of iodin and saturating its depths with the 

 same agent, the wound is cleansed, if it contains filth, by means 

 of a small curette. By using a small and sharp curette, one is 

 enaliled to cleanse the average wound quickly and almost pain- 

 lessly. 



In such cases, equal parts of tincture of iodin and glycerin 

 are employed. The wound is filled with this preparation and a 

 quantity of it is poured upon a suitable piece of aseptic gauze 

 or cotton and this is contacted with the wound. The extremity 

 is carefully bandaged and this dressing is left in position for 

 forty-eight hours unless there occurs, in the meanwhile, evidence 

 of profuse suppuration — which is unusual. 



One is to be guided as to the progress made by the degree 

 of lameness present. If little or no lameness develops, it is 

 reasonable to expect that infection has been checked; that the 

 wound is dry and redressing every second day is sufficiently fre- 

 quent. 



Where cases progress favorably, recovery (unless infectious 

 arthritis results) should occur in from ten days to three weeks. 

 Where extensive sub-coronary fistulae result, either from lack 

 of prompt or proper attention, the condition is then one requir- 

 ing a radical operation to establish drainage and to disinfect 

 if possible, the suppurating tissues.
