Ongoing saga with my horse/ vets..

Hello, I'll try to keep this short.

Some of you may remember that I admited my horse to have a performance work up at my local vets. (Note : not my usual vets but the only local one to offer this work-up). I was originally concerned with his lack of ability to engage his quarters, he humps his back / does very small bucks if really asked to move forwards, his canter is POOR with no engagement and he more often than not is disunited. He equally is very on the forehand and generally just seeming to lack any real gusto, which considering his history and breeding - something just doesnt add up! I was concerned with his back - thinking KS or SI.

On unloading at the clinic , he was instantly written off as being neurological with Grade 2 ataxia. He had the standard neuro tests which they felt that he was very poor on - and so he was the taken for x-rays, which came back clear. He was then admitted for a bone scan, of which there were no compressions but there was 'irregular uptake to both sacroilliac joints.' This was ignored, and he stayed down there for a further 4 days to have a tail biopsy to which it again came back clear.

He then was sent off for 6 weeks on steroids and had a re-exam. He was by no means significantly improved in this time, but definitely a marked improvement. After the 6 weeks however they said whilst there was improvement, there was still neuro issues and with an exaggerated HL action in trot. Given 6 weeks now just to do nothing and 'see what happens.'

After this I was a bit disappointed - and so sought a second opinion with the head vet at ''my'' vets. He said there was no way he was neurological, just perhaps a bit green and with muscle wastage behind - and so we bute trialled and 'cracked on.' This was 5 weeks ago and again, he was better on the bute but not anything majorly to write home about.

Finally, he has since moved yards to an area with lots of hill work and no school. I hired a school recently and he was back to being very backward etc and has since struggled with walking down hills. He has regularly been seen by chiro's/saddlers and is otherwise deemed 'fine.'

I just feel that some sort of issue with his sacroiliac is staring me in the face!!

I am going to ring ''my'' vet and seek to taking him down to their practise today, but I just wondered whether there is anyone else out there who had issues with a similar diagnosis?!

I tried. :o
 
It's a b***r when you can't get to the bottom of things.

I've no idea about the SI problems and how much they are affecting him.

But from a different angle, there were various things you mention which are problems with my gang. These include:

- lack of ability to engage his quarters (2 of mine have a very stilted hindlimb action, and 4 of them do not power forwards)

- humps his back / does very small bucks if really asked to move forwards. Yes, I've had this too. Max kind of concertinas and threatens to buck if told to move forwards (but with him it's even from walk to trot that he has a problem). Fox used to have a problem going into canter, and this gradually got worse til she could barely walk on - she was retired 2 years ago.

- his canter is POOR with no engagement and he more often than not is disunited. Fox had the disunited canter. Rose and Max have the lack of engagement in canter. (Fox was diagnosed with SI problems among other things)

- exaggerated HL action in trot. Yes, Fox does that. She has a gait more like a fibrotic myopathy horse, though she only has a small amount of FM in one hamstring (and her odd gait is remarkably symmetrical bilaterally)

- very on the forehand. Yes, similar with 4 of mine. At least with that, it seems reasonable to say they are trying to take weight off their hind end for whatever reason IMHO.

- seeming to lack any real gusto. Ah yes, that'll be work intolerance, lethargy or something. Max, Rose, Rock and Fox have been very good at that.

Was the tail biopsy for EMND? If so, what made them suspect it? And in particular, has he had blood tests done, do you have full copies of the report and do you know the exact values for the muscle enzymes (AST, CK and LDH)? Any previous blood tests...... and the same enzymes?

The only reason I ask that is because all the guys I've mentioned above as having at least some similar signs, turned out to have higher than normal muscle enzymes, indicating ongoing muscle damage.

High muscle enzymes can be caused by lots of things, but include genetic causes, inappropriate diet/exercise and lack of vitamin E/selenium. I'm pursuing it as being a lack of selenium in my guys, but no proof at the moment that it is that which has caused the signs.

- muscle wastage behind - that can be indicative of some muscle diseases, so again I'd look out any/all bloods he's ever had drawn

So the long and short from me (and I'm only a pony owner, I don't have any special knowledge) is that at least some of what you mention could be muscular stuff. But like I say before, I have no idea on the SI side of things.

Good luck however you pursue things. Oh, and if you think of having any bloods done, make sure they are done at home, when he's totally relaxed and hasn't been worked that day (or ideally for a few days beforehand) so that you can discount more common reasons for muscle enzymes being elevated by recent travel/work/stress.

Mine was treated for SI problems - his symptoms were reluctance to canter and jump and not wanting to go forward. He was diagnosed with a bone scan - unfortunatley he had other issues aswell. Feel free to pm me for more info
 
Thankyou both for your replies!

fff - thanks for your replies, I'm glad that someone else has the same problems as I've had so I'm not just plucking at thin air! The tail biopsy was done to establish how healthy the nerves were to his back legs (going back to the ataxia) but they were reaching fine. He holds his tail to one side - we suspect from a fall as he was a graded SJ'er before I had him so there is muscle damage there - but whether it extends like you say I've no idea!

He did have blood tests done when he was vetted, but that was back in August last year and up until now I've never doubted he was doped or similar so have never thought to check them! I expect they aren't obtainable now though! I have his animal history somewhere, so I'll check the values for his enzymes now!

foxy - Thanks, I'm positive there is some SI issues - especially as that is the one thing that the bone scan has indicated!
