Thoroughpin In Horses

The Body of the Horse
This section is all about what happens in and on the horse from nose to tail. It is divided into systems.

If you can;’t find a topic you are looking for, drop me a note in the contact section.

These photos have captions to express any thoughts I have on the picture. The idea here is for YOU to get ideas, so grab a cup of coffee, darken the room, grab a pen and paper to write notes, and sit back and enjoy. I have more shots and I’ll add them later as I have time.

The hallmark of identifying this is the ability to move the fluid from one side of the hock to the other. The cause is usually strain to the limb and it is usually just in one hock. They appear suddenly but without any lameness. It is considered a blemish but some believe it is a warning of bad things to come due to poor confirmation. I don’t agree and believe it is just an accidental strain such as a slip.

I recommend no treatment but some vets will tap it with a needle, drain the fluid, and inject a steroid. This works only if acted upon immediately AND a pressure wrap is applied. Think of the sheath recently injured as a fluid filled space easily drained. But in a short period of time, it no longer is a just fluid but laced with fibrin turning the empty space into something more like a sponge. It becomes very hard to drain an inflamed fluid sack such as a tendon sheath.

Wrapping the injured sheath is important because without it, the fluid will continue to leak creating a continued enlargement. Even after wrapping with pressure the injected sheath may enlarge again, but if treated early, this enlargement will subside.

Here is a video I shot and I’m sorry for the poor quality, but you will get the idea.
