Flash - Navicular Rehab Case Study

I purchased Flash in August of 2020 to be one of our school horses used during our trimming courses and because he had been diagnosed with Navicular Syndrome by the previous owner's Vet and I wanted to both help improve his condition and study him.

I am somewhat skeptical of the diagnosis as it was made without radiographs to confirm, and was only based on the Vet's opinion of how he was moving at the time. If you look at his initial photos and hoof conformation I struggle to understand how a diagnosis could have been made solely by assessing his movement with his hooves in that condition.

Either way I am moving forward under the assumption he may have Navicular Syndrome and treating him as I would treat any horse; with proper frequent trims, a good diet and turnout 24/7 on my track with my herd. 

August 25 Initial Set Up Trim 

​The following video is from Aug 25 2020 and was taken immediately before pulling the shoes and trimming.

Though it's not the best video to showcase his movement, you can see that he us kicking forward sand with his front hooves. This is due to toe first landings.

​August 27 2020, 2 days after trim with Easyboot Cloud boots.

He is still pretty stiff through the body, and if landing flat, avoiding using his heels.

This is by far the best I have seen him moving. Still landing flat and with hesitation, but overall significantly improved from before. 

March 25 before and after trim pics

After this trim Flash was sounder then he has been since he arrived. I have also noticed a huge change in his behavior over the last month. He has finally settled into the herd and has started to approach me and ask for attention. Something he was never interested in before. After this trim I even rode him lightly in the arena for a few minutes, this was his first ride since we brought him home, and probably his first ride in over a year. 

I would still like to see him grow in more hoof wall connection as well as stronger digital cushions. As he grows in more wall connection I also expect that his concavity will increase and his soles will thicken, resulting in less bruising. 

April 19 Trim and Composite Application

Flash has been doing well, he has gone from unsound to sound on the track where he lives and sound in the sand arena. Because of his progress we have started riding him and I have found he is tender on rocks and hard surfaces. I wanted to try a composite application to see if we can build more sole thickness and continue to ride him. I glued on Easyshoe Performance Shoes, with a soft sole packing underneath and topped the application off with a thin layer of 3M casting.

December 2021 Update

Watching Flash improve has been very emotional. He has gone from a very shut down horse to an in your pocket and really friendly guy. He is a favorite among the youth that I work with and has been sound enough to use in the program since the August 2021. He spend most of the summer in Easyshoe Versa Grip Lights glued on with the 11 finger tab system. This product packed with dental impression material both protected and stimulated the back of his hooves and caused his frog to grow in wider and thicker, as a result of the improving health of the digital cushion. 

Even though I was watching his soundness and comfort improve I was feeling a bit discouraged with the progress of his hooves until I put these pictures from the beginning of his journey along side the current hoof pictures. I can see that the overall angle of the hooves has changed dramatically and the heel is much farther back underneath the hoof. Also the entire back of the hoof has changed. The frog is wider, but the heel bulbs are also wider and more "full", with a much stronger digital cushion under there. 

While there is still improvement to be made I am much happier with Flash's progress having looked at how far he's come.
