SIDE BONES.
—On either side of the coffin bone there is a cartilage which may in certain cases become hardened by deposits of mineral matters, which may thus lead to lameness. Side bones are situated on one or both sides of the leg and bulge above the upper portion of the hoof. They may be the result of inflamed conditions, bruises or troubles like corns or hoof cracks. Slipping on the stony pavement is a frequent cause, as well as the great weight of the bodies in heavy horses. If the wagon tongue falls on the foot at this point, the cartilage may be injured and induce the disease. The swelling is first noticed just above the hoof or near the heel. Lameness soon follows.
SIDE BONES
When the cartilages on either side of the foot of a horse just at the top of the hoof and close to the heel turn to bone, side bones are the result.
The treatment usually recommended for side bones consists in the free use of cold foot baths or cold water bandages for a week or more. Tincture of iodine applied to the swollen parts is very good. A blister applied after the water applications have been made for a week or so, is used by many veterinarians. The blister is made of 2 teaspoonfuls of cantharides mixed with 4 tablespoonfuls of lard. It is rubbed in well with the fingers and allowed to remain for 24 hours, when it is washed off and applied a second time the following week. These applications are continued until the lameness disappears. If this does not bring permanent relief, then firing of the injured parts and several months’ rest will be necessary.
