The New International Encyclopædia/Spavin, Bone

SPAVIN, Bone. An inflammation of and bony deposit on the flat bones of the lower and inner part of the hock-joint of the horse. At first there is tenderness, local heat, swelling, and lameness, but as the inflammatory stage passes the lameness is less perceptible, although the horse still continues to go stiffly. If the lameness is only slight it usually disappears after a little exercise. The animal should be given rest.
