Lameness in Horses.

"blemish caused by firing it would always be considered the more satisfac- 

 tory treatment. It is of a surety always the most certain. Point firing 

 is to be preferred before line firing, and the punctures, of which from three 

 10 five will usually suffice, should be sufficiently deep as to penetrate into 

 the bony growth. 



While complete rest is not absolutely essential, any work which imposes 

 a strain on the hock will retard the completion of the bony union. Conse- 

 quently it is advisable to turn the horse out for a spell of two or three 

 months, during which time the foot of the affected limb should be shod 

 with a high-heeled shoe, so that strain on the hock may be lessened. 



Jarde. 



This condition, sometimes designated " false spavin," is a bony enlarge- 

 ffnent of the head of the outer splint bone corresponding in situation on 



Figs. 97 and 98. Jarde 



the outer aspect of the hock to spavin on the inner aspect. (Figs. 97 and 98.) 

 Though unsightly it is a condition of little importance as it is seldom or 

 never associated with lameness. 



Curb. 



Curb is the common name given to an enlargement situated at the back 

 and lower part of the hock. (See Figs. 85, 100, and ici.) It is best seen 

 from the side, and appears as a Imlging (about three to four inches from the 

 point of the hock) in an otlherwise straight line from the point of the hock to 

 the back of the fetlock. The enlargement is consequent on a sprain (with 

 swelling) of a ligament (the calcanco-ciihoid ligament) which runs down- 

 wards from the point of the hock and is inserted into the lower liones of 

 the hock and the up])er part of the cannon bone posteriorly. 



One function of this ligament is to keep the hock bones in position, and 

 in severe cases of curb when it has been inordinately sprained the lower 

 bones of the hock, particularly the cuboid and small cuneiform bones, 

 tmav be actually displaced and spring backwards.
