Special Injuries of Bones, Joints and Muse les. 441 



ness to pressure on the seat of tlie sprain. Swelling and 

 heat are rare because of the depth of the lesion. In cases 

 of any standing the muscles of the quarter waste. 



Treatment. Long continued rest, with at first fomenta- 

 tions, and later, active and repeated blisters, or eyen the 

 hot iron applied in points. Some chronic cases do well 

 under a combination of exercise and counter-irritants as 

 follows : rub the affected quarter with oil of turpentine, 

 then take out and exercise in a circle until covered with 

 perspiration ; then return to the stable, rub down and 

 clothe with a doiible wet blanket over the lame quarter. 

 Repeat daily for some time. 



DISPLACEMENT OF THE ABDUCTOB PEMOEIS. 



Lean cattle are subject to a peculiar form of nip lame- 

 uess, from displacement backward of the large muscle 

 which plays over the prominence at the head of the thigh- 

 bone. The high, bony process presses on the anterior 

 border of the muscle, preventing it from resuming its 

 natural position. The anterior border of the muscle forms 

 a prominent painless cord extending from behind the hip- 

 joint to below the stifle. Li moving, the toe is dragged 

 along the ground, being extended backward, and the limb 

 is flexed with effort and often in a sudden and convulsive 

 manner, and accompanied by a dull sound. These symp- 

 toms are most marked if the animal is made to step over 

 a bar of six or eight inches high as he leaves the stable. 



Treatment. Some recover under good nourishment with 

 or without blisters, but usually it is best to make an incis- 

 ion over the front of the cord an inch or two below the 

 head of the thigh-bone and cut the border of the muscle 

 across with a narrow-bladed knife. The animal may be 

 kept quiet by the bull-dog pincers in his nose, and by 

 drawing the opposite limb forward with a line passed 

 through a collar.
