Fig. 32. 



the least deviation from the straight line proper to the limb 

 will be at once detected. 



The seat and true character of Curb will perhaps be more 

 satisfactorily explained and understood bj reference to the 

 annexed engraving. 



The engraving represents the 

 outer side of the left hind limb of a 

 horse, dissected. The figure is partly 

 diagramatic. In describing the en- 

 graving, I shall merely refer to those 

 letters which relate to the structures 

 more or less involved in Curb ; a the 

 tendo achilles, two tendons of great 

 strength which are situated above 

 the point of the hock and behind the 

 limb ; h the os calcis, or the bone 

 which forms the prominence of the 

 hock ; e the head of the outer splint 

 bone ; df the flexor tendons — these 

 tendons are a continuation ofthe tendo 

 achilles ; c the calcaneo cuboid liga- 

 ment. This ligament arises towards 

 the top of the os calcis bone 5, and 

 is inserted into the back of the small 

 bones of the hock, and also to the 

 head of the outer splint bone. Now, 

 Curb is simply a sprain of this liga- 

 ment; sometimes, however, ib is 

 associated with sprain of the flexor 

 tendons at the point d, in which easel 

 the swelling will be more prominent,'"""''^ 

 and the lameness will also be more apparent.
