- n. A morbid growth or deposit of bony matter and at the sides of the coronet and coffin bone of a horse.
from The Century Dictionary and Cyclopedia
- n. The hip-bone.
- n. An abnormal ossification of the lateral elastic cartilage in a horse's foot. Side-bones occur chiefly in the fore feet of draft-horses, and are an occasional cause of lameness.
- n. The disease or disordered condition in horses which causes the lateral cartilages above the heels to ossify. See the quotation under ring-bone.
- n. In carving, either half, right or left, of the pelvis of a fowl, without the sacrarium; the hip-bone or haunch-bone, consisting of the coalesced ilium, ischium, and pubis, easily separated from the backbone.
There is a wide margin of difference in respect to the degrees of severity which may characterize different cases of sidebone.
A sidebone consists in a transformation of the lateral cartilages found on the wings of the coffin bone into bony matter by the deposition of lime salts.
"Here, waiter! bring me a sidebone of chicken, some green pease, string-beans, pickled beets, boiled cabbage, a plate of macaroni, and any other vegetables you may happen to have; and don't be all day about it," said the passenger on the other side of Major Billcord.
There are no miraculous cures for either condition, but like many other arthritic states, it's possible to manage ringbone and sidebone once you understand what you're dealing with.
Ringbone and sidebone, two closely related orthopedic problems of the lower limbs, used to be considered almost inevitable hallmarks of the working harness horse, and they are still distressingly common in horses which deal with heavy-duty concussive forces and those with certain conformational problems.
Poor conformation and / or poor shoeing can put a horse at risk for sidebone.
"In terms of shoeing, I usually ignore sidebone -- it's something that doesn't look particularly good on a radiograph, but it's not a major issue as far as I'm concerned."
Like ringbone, sidebone tends to develop in older horses; in fact, it's considered almost a normal rite of passage for the lateral cartilages to ossify to some degree over time, and the process is only designated as sidebone when it is premature or happens abnormally fast and leads to lameness.
The good news is that sidebone doesn't usually result in major lameness.
I have to say I've never seen a diagnosed sidebone that caused lameness on its own.
