326 THE CONDITION OF HUNTERS 



THOROUGHPIN 



A thoroughpin, if present, is situated at the back 

 of, and just above the point of the hock. It shews 

 itself as a bulging or slight distension, either upon the 

 inner or outer side, but when manipulated with the 

 finger, the latter by pressure causes the bulging to 

 grow larger to either one side or the other. In plain 

 language, the fluid can be pressed through from side 

 to side, hence the name — thro-pin, from whence 

 the term thoroughpin has been derived. Sometimes 

 both sides bulge. It constitutes unsoundness, but 

 very rarely causes lameness, yet nearly all veterinary 

 surgeons reject horses having it. 



Far too much importance is attached to this simple 

 matter. 



BURSAL ENLARGEMENTS 



Wind-galls 



Puffy swellings in the neighbourhood of joints 

 and tendon sheaths have been, though erroneously, 

 termed wind-galls. 



Such swellings are specially common at or about 

 the fetlock joints, but by no means confined to these 

 situations. It is very seldom that a bursal enlarge- 

 ment causes lameness. Horses that are prematurely 

 worked, or horses that are hard-worked, commonly 

 show swellings of this nature about the joints. 



The hock and knee are frequently affected. If 

 large, the movement of the joint, etc., is hampered.
