OPEKATIONS ON BONES. 



the parts involved, complications are apt to be present which are 

 likely to disable the animal for life. 



If there is no displacement a simple adhesive dressing, to 

 strengthen and immobilize the parts, will be sufficient. A coat of 

 black pitch dissolved with wax and Venice turpentine, kept in place 

 over the region with oakum or hnen bands, will be all the treat- 

 ment required, especially if the animal is kept quiet in the shngs. 



Displacement cannot be remedied, and reduction is next to 

 impossible. Sometimes an iron plate is applied over the parts 

 and retained by bandages, as in the dressing of Bourgelat (Figs. 

 266, 267) ; and this may be advantageously replaced by a pad of 

 thick leather. In smaller animals, and also in larger ones, the 

 parts are retained by figure-8 bandages, embracing both the nor- 

 mal and the diseased shoulders, crossing each other in the axilla 

 and covered with a coating of adhesive mixture.

Fractures of the Humerus. — These are more common in small 

 than in large animals, and are always the result of external trau- 

 matism. They are generally very oblique, are often comminuted, 

 and though more usually involving the shaft of the bone will in 

 some cases extend to the upper end and into the articular head. 

 There is ordinarily considerable displacement in consequence of
