STRAIN OF THE BACK SINEWS. 231 



lateral or side motion. The injury we are considering consists 

 in a strain of the capsuhir ligament of the joint, by the foot 

 being forcibly thrown to one side, which is most likely to occur 

 from the horse treading on a stone, or getting his foot fast in 

 the mud, and bringing it out in a twist. 



Spnjjfoms. — Lameness of the foot affected is the most notice- 

 able symptom of strain of the fetlock, but, as lameness occurs 

 in many other injuries, it furnishes but little evidence of the 

 locality of the difficulty. There will be found heat and tender- 

 ness, and perhaps swelling, at the point injured, and these, 

 with the absence of the symjotoms of other injuries, must be 

 relied on in determining the case. 



Treatment. — Soon after the strain occurs, or while there is 

 active inflammation, known by the heat, swelling, pain, and 

 soreness, apply a flannel bandage around the part affected, and 

 keep it constantly wet with the following: 



Take — Tincture of arnica 1 to 4 ounces. 



Cold water 1 quart. 



Mix. Continue this treatment until the inflammation is all out of the part. 



But if the case has been neglected for a number of days, 

 apply a blister over the part most affected, but not so as to go 

 clear around the leg. After the first is well, another may be 

 applied at the other side. The blister may have to be applied 

 several times over the affected part. The liquid blister may be 

 used, being careful not to let it run on the heels, or the paste- 

 blister will answer. 



STRAIN OF THE BACK SINEWS. 



This is an inflammation of the sheath of the tendons, or 

 sinews, at the back of' the cannon-bone, between the pastern 

 and back of the knee. It is not correctly named, for the 

 tendons are incapable of being sj^rained, as they are not 

 elastic. The sheath in which these strong tendons work is 

 composed of a dense, fibrous substance, and is moistened on
