OPERATION FOR PICKED-UP NAIL. 45 1 



On the 8th the temperature was 38*3° C. Occasional lancinating 

 pain was still noted. 



On the gth pain had ceased ; the temperature and principal 

 functions were normal. On the following days the animal began to 

 place weight on the foot. 



On the 14th the dressing was removed ; the wound was granulating 

 throughout, and visibly disposed to heal. A shoe and dressing were 

 applied. Weight was readily placed on the limb, and lameness was 

 trifling. 



On the 25th the dressing was again renewed. Healing was almost 

 complete, and lameness scarcely noticeable at a walk. 



OPERATION FOR PICKED-UP NAIL. 



155. A ten-year-old gelding suffering from picked-up nail in the 

 middle zone of the near hind foot. Treatment by thinning the horn 

 and poulticing had only resulted in the condition becoming aggravated. 

 The horse was sent to hospital on the 14th April, 1896. 



No weight was placed on the diseased limb, the animal walking on 

 three legs. The injur}- in the sole traversed the anterior part of the 

 external branch of the frog, which was very prominent at this point 

 in consequence of swelling of the subjacent tissues. The sinuous 

 wound discharged a large amount of yellowish viscous pus. The 

 flexure of the pastern was swollen ; temperature 3g'o^ C. 



Treatment. — Thinning of the sole and frog ; immersion of the foot 

 in warm carbolic solution for twenty minutes ; application of peat 

 wool compresses soaked in the same solution. 



Next day the animal lay continually. The affected limb was moved 

 spasmodically in consequence of darting pain. 



The horse having been cast, and the limb fi.xed in a convenient 

 position, the partial operation for picked-up nail was performed. A 

 portion of the plantar cushion was removed ; the sinuous tract laid 

 open in front and behind, and an elliptical piece removed from the 

 margins of the plantar aponeurosis, so as to produce a button-shaped 

 aperture three eighths of an inch in length. 



The small sesamoid sheath, being full of purulent synovia, was 

 irrigated with warm 2 per cent, lysol solution, powdered with calomel, 

 and enveloped in a cotton-wool dressing. 



Next day the animal showed evidence of acute pain. It only rose 

 to eat, and even then left a portion of its food. Temperature 38'6° C. 

 Less signs of lancinating pain. 



During the following days the condition remained stationary ; 

 temperature 387° to 395° C. 



On the 22nd the dressing was renewed. The operation wound 

 had commenced to granulate ; there was little pus ; the parts were 

 irrigated with lysol solution, and dressed with calomel. 



From the 23rd to the 30th the animal remained lying for the 

 greater portion of the time ; temperature 38"5° to 39*3° C. 



On the ist May the dressing was changed. The flexure of the 

 pastern was swollen in consequence of an abscess having developed.
