1
Posterior to the position we have named, the only structure to be injured is the plantar cushion.
2
Now, with the animal shod, the plantar cushion does not itself, as normally it should, receive concussion.
3
Each incision thus made should be carried deep enough to cut through the substance of the plantar cushion.
4
The inferior border is attached in front to the basilar and retrossal processes, behind which it blends with the plantar cushion.
5
We shall readily understand this when we bear in mind the anatomy of the parts concerned, especially that of the plantar cushion.
6
The sole is produced by the velvety tissue, a thin membrane covering the plantar cushion and other soft tissues beneath the coffin bone.
7
By the shoeing the frog is lifted from the ground, and the plantar cushion, together with the cartilage, taken largely out of active work.
8
When the frog is severely bruised the injury is followed by suppuration beneath the horn, and at times by partial gangrene of the plantar cushion.
