sidebone


Also found in: Dictionary, Wikipedia.

sidebone

ossification of the alar cartilages of the third phalanx of the foot of horses. Attention is usually drawn to the disease by lameness but it is possible for the lesion to be far-advanced and the gait to be normal. There may be obvious enlargement at the site and the cartilages can be felt to have lost their flexibility.
