Background: 8YO gelding. Always been very sound. Does low level work jumping under 2’6” with me about 2x a week and usually teaches a lesson or two also.
On the 19th we warmed up at the walk and then picked up the trot. About 100 feet into the trot it was like his whole hind end just broke. Really, really lame, and felt horrible. I got off, got the lunge line, and lunged him both ways (video 1 and 2) but weirdly he was sound again. Maybe ever so slightly lame in the right hind, but no way near what it was previously. I assumed he stepped on a rock, got back on, and finished the ride, which included jumping. Interestingly he is very picky about jumping, and if he is in pain at all will refuse and throw me to the ground, so the fact that he happily jumped around the course tells me he was not in pain.
Two days later I rode him again. Same thing happened with trot warmup. Now clearly this was not a rock so I got off immediately after video 3. It’s filmed by my PIVO, so excuse the part where it videos the sky; it does capture the lameness towards the end pretty well.
Vet came out Monday. He was so horribly lame at the trot that she had a hard time deciding exactly what part was lame, but narrowed it down the the right hind. I elected to start nerve blocking. We really thought it was going to be something higher up, but wanted to eliminate the possibility of it being lower down, so his first block was in the fetlock. He trotted off pretty much completely sound on that block. So I elected to X-ray it.
I’ve included all the X-rays here, but I’ll be putting them in the next post so I don’t overwhelm the COTH uploader. My vet really expected to see a broken coffin bone or something with how lame he was, but there was just nothing.
He also has no swelling or heat in the leg.
Ideas? Thoughts? Currently our next steps are waiting two weeks to make sure it’s not an abscess, and then going in for an MRI
