enlargement for a short time; treatment is usually 

 unsatisfactory, pressure by the use of a bog spavin and 

 thorough pin truss being the best. 



Thoroughpin is rarely absent when bog spavin exists, 

 and is due to the pressure of the fluid constituting the 

 bog spavin on the bursce of the perforans tendon, which 

 is thus pushed out of place. This lesion appears as a 

 swelling at the back part of the hind leg, just above the 

 point of the hock and in front of the hamstring, it can 

 be pressed from side to side with the finger, the treat- 

 ment is the same as for bog spavin. In draft stallions 



may be due to a sprain of 

 the tendons, a serious con- 

 dition. 



Curb is an enlargement (a 

 bowing out) at the back 

 part of the hock, about six 

 to eight inches below its 

 point, usually it is de- 

 scribed as a sprain of the 

 ligaments at the back of 

 the hock, quite often the 

 bones of the part are af- 

 fected also, the enlarge- 

 ment being due in many 

 cases to the pushing out- 

 ward of the ligament by 

 the inflamed bone. To de- 

 tect the enlargement it is 

 often necessary to stand to
