This is half of the elbow joint from a jumping pony. We are looking at the humeral side of the joint.
In the top photograph you can see what a normal joint surface should look like — smooth, white and glistening. That glossy layer is articular cartilage. It protects the bone and allows the joint surfaces to move over one another with minimal friction.
The lower photograph is from the pony.
He had previously jumped happily in competition, but then began to refuse. After many investigations — and a lot of money spent on body workers, farriers and even communicators — he did not improve.
After euthanasia, I was given the opportunity to examine his joints.
This is what I found.
The surface that should have been smooth and glistening had been worn away. Instead of healthy white cartilage, there was exposed, reddened and ragged bone. The protective layer had failed.
This is not a training issue. This is not naughtiness.
This is pathology.
