CAPPED ELBOW, OE SHOE BOIL. 



This is commonly called Shoe Boil,, and consists of an enlarge- 

 ment at the point of the elbow, due to an injury. Capped elbow 

 is a very common condition,, and varies considerably in character, 

 size, etc. (See Fig. 35.) 



Causes. The most common cause of this condition is the 

 elbow coming into contact with the shoe when the animal is ly- 

 ing down. It may also be caused by the elbow coming in con- 

 tact with the hoof, the ground, or the belly band, etc. 



Symptoms. At first there is only a slight irritation of the 

 part, producing more or less enlargement. In some cases there 

 is considerable inflammation, which terminates in a collection 

 of fluid. In aggravated cases this fluid solidifies and forms a 

 hard tumor on the point of the elbow, and in some cases an ab- 

 scess may form.
