264 VETERINARY SURGICAL THERAPEUTICS,

reported two observations of rupture of this muscle: in a twelve-year- 
old horse destroyed for dissection, he found on both legs a cicatrized 
rupture of the long flexor of the forearm; in a seven-year patient which 
was very lame in the left fore leg, he found in that muscle five cystic 
pouches, evidences of previous ruptures, and also the cicatrix of a com- 
plete rupture of its inferior tendon. Nesbit has made the post-mortem 
examination of a horse in which on both legs the coraco-radialis muscle 
was torn from its scapular attachments.’ Peuch records the following in- 
teresting observation: A horse running away struck against the angle of 
a wall, fell down and had some difficulty in getting up. On examination, 
he found that “a little below the right scapulo-humeral articulation, in 
the middle part of the long flexor of the forearm, there was an oblong 
tumor the size of the fist extending to the middle of the anterior brachial 
region; it was hot and painful.” The animal rested only on its toe. 
The general symptoms were such that two days afterwards it was de- 
stroyed. At the autopsy, there was a diffused hemorrhagic center, a 
partial rupture of the mastoido-humeral muscle and on the bicipital 
groove a rupture of the width of two fingers; also a transverse solution of 
continuity of the coraco-radial muscle. At the autopsy of a horse that had 
hown symptoms of sprains of the loins, Rigot found the great psoas 
swollen, softened and partially torn. In tears of the g/udeal muscles, of 
the superficial (long vastus) especially, the diseased leg is dropped, its bony 
supports half flexed; in walking, the step is shortened, the motion of 
the leg is limited, the toe drags on the ground; later there is a local 
simple depression, or a deformation of the region brought on by the 
atrophy of the muscle. The troubles of locomotion last sometimes for a 
long while. Ina horse cast on the left side for castration, Raynaud 
observed, on the right gluteal region, near the origin of the tail, a some- 
what large swelling, though not very painful; in walking, the muscles 
of that region contracted with difficulty, the leg was dragged along and 
moved in abduction. The author made a diagnosis of rupture of the long 
vastus and middle gluteus. There remained a slight motion of abduction 
and a depression at the point of rupture. Partial ruptures and those of 
the patellar muscles are not rare. Delwart, Haubner, Schmidt, Hoffmann, 
and Bassi have recorded instances of them in horses; Hollmann and 
Meyer, in cows. Delwart says he has observed the laceration of the 
* Professor Robertson has an animal destroyed because of severe osteo poro- 
sis. There wasa great deformy, his body hanging between both fore legs, it 
the scapulz having a horizontal position. At the post mortem it was found 
that on the right side the coracoid process had given way and on the left the 
tendon of the coraco radialis had ruptured about three-quarters of an inch from 
its attachment. (Amer. Vet, Review, vol. 21, p. 623.)
