I am looking for serious help from the Hunter/jumper group. I have an ultra fancy and well known show horse that was given to me. I knew that he had been nerved in one half of his front right foot. He was serviceably sound July 2012 when I got him through December 2012 and then stepped on his shoe and drove a clip into the sole. No bleeding. Immediately put on antibiotics. Oddly his leg was thick and it looked like a suspensory injury. Xrays all looked good and ultrasound showed some inflammation but no tears or lesions. Treated with some injections just to be sure. Still just not quite right but able to be turned out and not head bobbing. Vet blocks and seems it is not the foot nor pastern but mid leg. Vet suggests stall rest for a few weeks to see if it helps. In actuality it worsened. Horse is barely able to walk on that leg. Will put pressure on foot when it is soft like shavings or grass. The pastern is think and hard. So I start to think maybe he has an abscess because he did have a deep bruise in the hoof. I am thinking abscess that can’t find its way out. Ultrasound the pastern and no obvious issues. Maybe a slight calcification but hard to tell. Start horse on antibiotics and sweat the pastern with special stuff. In three days the pastern went from rock hard to slightly hard and soft in some areas. You can see the nerving scars from the past. Horse is walking a tad better. Xrays show clear. I am hopeful some other hunter/jumper person has experienced this and can offer some additional thoughts.
We don’t have snakes or varments so no bite would cause this. No puncture wounds anywhere.
OP - you might want to transfer this to horse care; no reason to limit input to just hunter people when all horses get lameness issues...Sounds like you've done a lot to figure out the problem; is there any thought that the nerves have regenerated? Other than that, no brilliant ideas, except you may want to try a different vet - is there a vt school in your area? Any lameness specialists?
We don't get less brave; we get a bigger sense of self-preservation........
I did know a horse that was nerved and then soon developed enlarged, deformed, firm pasterns. Not my horse, but my understanding was that it was from extensive low grade soft tissue damage that worsened over time.
