706 SHOEING. 



shoe of an equal thickness all the way round, with perhaps the 

 inner part straightened a little. Raising the inside heel, which 

 is the method in general use, while it tends to throw the ankle 

 out, tends also to throw the foot in, as it is carried forward. It 

 also brings such unequal strain upon the ankle joint as to some- 

 times cause serious injury to it. Fig. 552 is introduced to show 

 the bad effect of this. The inner condyle of the joint is worn 



down or eroded over one-eighth of 

 an inch, and, by its friction, cut in 

 through the cartilage of the oppos- 

 ing part so as to conform to the an- 

 gle shown in the bones as represent- 

 ed. There is also a large accumu- 

 lation of bony deposit on the outside, 

 grown by the inflammation excited, 

 showing the extremely bad effect of 

 forcing an unequal bearing on the 

 joint, and throwing the foot out of 

 line.

badly ; in such a case the ankle must be protected. In all cases 

 when the ankle is cut, the swelling and soreness increase the dif- 

 ficulty, and should be guarded against by covering. If the irri- 

 tation is kept up, and this is not done, it may result in perma- 

 nent enlargement of the part, which ivould afterward increase 

 the liability to be hit. This can be prevented only by coverings, 

 or by being protected by the ordinary simple means, until the in- 

 flammation subsides and the injury heals. I include here Prof. 

 McLellan's directions : 



"Treatment for interfering, to be rational, must take into account 

 the causations. Thus, if the toes turn out a very common cause 

 of interfering they should be inclined in all that is possible. This 

 can be accomplished by bending the outside web of the shoe from 

 its inner to its outer border, making the edge through which the 

 nails are driven, quite thin. Or if calks are used, the toe calk can 

 be welded nearer the inside than the outside toe, and the toe calk 

 beveled at the expense of its outer extremity. If the kneo is 

 banged, but light shoes are indicated. Lightness in the shoo is al- 

 ways desirable in the hind feet, and if the season of the year per- 

 mits, tips will he found very effective in prevention of interfering.
