36 LAMENESS IN THE HORSE. 



clinical standpoint, it is well to classify this lameness 

 according to its approximate seat, extent and nature. 



DISEASED CONDITIONS OF THE SHOULDER JOINT 

 AND ITS NEIGHBORHOOD. 



Inspection. — Swinging-leg lameness or mixed lameness. 

 Turning the animal suddenly upon the lame leg may increase 

 lameness. In cases of long standing, atrophy of the shoulder 

 muscles is noticed. 



Palpalion. — Pcri-articular exostoses may be felt about the 

 scapulo-humeral articulation. Eaising and lowering the 

 foot may cause pain or show limited motion. 



INFLAMMATORY SWELLINGS AND NEW GROWTHS. 



Anatomy ; Glands. — The prescapular r^lands form a kind 

 of chain along the ascending branch of the inferior cervical 

 artery, beneath the mastoido-humeralis muscle, descending

 brachial glands c-o situated inside the arm, one group near 

 the ulnar articulation, the other near the insertion of the 

 teres major and latissimus dorsi muscle. (Chauveau.) 



Inspection. — Lameness is most noticeable during the

Palpation. — Tumefaction of the axillary and prescapular 

 glands may be felt, as in glanders, strangles and local 

 infection. 



THROMBOSIS OF THE BRACHIAL ARTERY. 



History. — Lameness appears regularly as soon as the 

 animal is sharply worked for ten or fifteen minutes, the 

 horse sometimes being in danger of falling; after resting
