When Does Ringbone Happen?
Types of Ringbone
When a bone or joint is put under uneven stresses or wear the joint compensates by producing more bone in that area to help to stabilize the area. With ringbone this can be problematic if it interferes with the joint itself as it will limit the movement of the joint.
- High Ringbone - This is a bony growth that forms around the lower edge of the long pastern or the upper part of the short pastern.
- Low Ringbone occurs around the lower part of the short pastern and the upper part of the pedal or coffin bone.
- With High ringbone the bony growth can be felt and sometimes seen around the pastern joint.
- With low ringbone it can only be felt if it is around the coronet band otherwise the ringbone will be hidden under the hoof wall.
