Any ideas on strange lameness

I currently own a 13yo 17hh TB gelding and have had him since he was 4yo. He has always been 'accident prone' with many things go wrong.

13 months ago I put him out in a paddock (40 acres, grassed with a small creek) and when I grabbed him the next day he was severely lame on his hind near side leg. He would put the foot down on the toe and then 'snap' the heel down. I have seen him do this previously but it was only the odd time, not prolonged.

I pulled him out of the paddock and called the vet. The vet was stumped as during the consult he started doing it on the other hind leg also. Flexion tests were performed and the vet went over him and concluded that he thought it was spinal somewhere with nerve involvement and reccommended taking him to another vet that specialised in strange lameness.

However, the lameness was intermittent and came and went and so when I took him to this other vet I was told there was nothing wrong with my horse in a very abrupt way. Just to note that unlike the first and third vet this vet never walked or moved my horse around to see the lameness, he just went on feel and stated that it was just the way the horse moved. However, having owned the horse for a long time I knew this was incorrect as he had never walked like this before.

I also took him to a third vet who told me that he agreed with my original vet that it was nerve damage but it was out of his area of expertise and he recommended spelling.

So I took him home and put him back out in the paddock and in January he got extremely bad abcesses in both back feet that resulted in him being stabled for 6 weeks and then corrective shoeing. He seemed to get better throughout all of this rest and so finally when his feet were healed I decided I'd try leading him off of my other horse.

He started working OK being ponied and we were walking up to 8km a day so I decided to get on him again. The day I got back on him he dragged his feet along the road and would not walk without dragging both back feet. By the time I walked him home he was bleeding from the front of both back feet but did not seem to realise it. It was as if he couldn't feel the feet.

So I called my farrier and had the shoes moved forwards and brought him to a chiropractor I had used previously as the two vets I trusted had both believed it to be nerve damage in the spine. She treated him for 6 weeks with no improvement.

Throughout all of this he has been getting steadily worse to be lame permanently now though the type of lameness changing. Sometimes he will be 'traditionally' lame ie just put the hind legs down for as short a time as possible, sometimes he will snap the fetlock, sometimes he will refuse to move.

The last few weeks he has been deteriorating rapidly, often refusing to move or walking with his feet almost crossed underneath his body, as if he can't hold his legs straight under him.

Anyway, I got the farrier out to him a few days ago and the near side hind he could only pick up directly underneath himself and the off hind he wouldn't bend the fetlock or hock and kept his leg completely straight, as if on a pendulum.

And today he tried to canter across the paddock and wont put the off hind on the ground at all in canter but looks pretty good on it in walk.

Basically, I am running out of ideas to try with him and am trying to avoid the necessity of having to put him down - I am more than happy for him to retire as a paddock pet if I know he's not in much pain.

Does anyone have any ideas on what the problem may be or any treatments?

Since the problem has got so much worse over the last few weeks I am getting the vet back out and am going to ask for tests as no xrays or blocks were done due to everyone thinking its nerve damage. Is there any specific tests anyone would recommend or things to watch for?

Any ideas or help would be most appreciated...
 
Mmm, can't be of much help I am afraid but I didn't want to read and run so I'll bump this for you.

For what it's worth R had neurological problems due to the saddle pinching his spine. It took ages to diagnose (18 months) but it was solved when we changed his saddle to a treeless which put pressure on his spine in a different way. His symptoms were slightly different but I suppose anything goes with neurological problems. He was unable to track up, getting progressively much, much worse and also he would suddenly spin and take off (we think because of the sudden pain).

Hope you get to the bottom of it but I think you may need some more investigations. A scintigraphy might help if not to eliminate other possibilities?
 
Thanks.
He has only been under saddle the once in 13 months though - would symptoms still be showing?
Ive been reading more on this and other sites and have noted that maybe symptoms have been around a lot longer as he's always been really grumpy to collect or work in an outline. He does it but very very grudgingly and then as soon as you let him out he puts his nose on the ground and is quite happy.
Anyway - Im just running out of ideas...
 
You should get further tests done but have you had a physio to look at him,they are often more hands on at dealing with these unusual problems and if he has been moving awkwardly for some time there could also be muscle damage.

A GOOD equine physio should be your first stop now - the vets you have used have been of little help!!

It sounds like it could be severe sacro-iliac problem - perhaps with stifle involvement - and it will probably need a mujlti-disciplinary approach. I have a filly with sacro-iliac problems (guessed at by a good equine vet) and confirmed by physio.) The physio sent horse back to vet for steroid injections into back and SI to ease inflammation so he could work on the area. She is ow much improved - though still a 'work in progress'! Your chap is older - and from sounds of it - has had the underlying problem for a long time, so there will be LOTS of consequential problems to deal with too!
 
Hello,
My horse is currently undergoing lameness investigations. She had been absolutely fine going really well then i thought her back was sore laid her off for a couple of weeks until physio came and said slight sore back nothing to be worried about but she is slightly lame behind. Got vet to check her quickly whilst on the yard saw bilateral lamenesss (lame in both back legs) and maybe one in front. Suggested on that initial quick assesmen macybe arthritic hocks. Horse went to vets for lameness work up this week lame on both behind, mildly and intermittantly lame in front. Weakness in back end and ataxia (not quite noing where her ffeet are) very slightly. They blood tested, clear. X-rayed neck saw slight artrhritus but no narrowing of the spinal cord space. They thought this might indicate the lameness. Also x-rayed hock while at it as most common cause of hind lameness (11yo horse hocks of 2yo) They have said that they can't nerve block her very effectively when lameness is intermittant very mild so i am to ride her to make lameness worse!! Also suggested bone scan to see areas of bony changes/ confirm neck is problem. Then we could steroid inject neck.
Slight simularities to yours in a way?
 
So the flexions got no positive response and this is why they did not proceed with nerve blocks of the legs and then diagnostic tools?

A friend of mine recently had her horse's sacro-iliac blocked (at least I think this happened) and the hores's back too I think. And this is how she knows her horse's issues are in the back/sacroiliac etc. As well she had some xrays and ultrasounds where they could get images. This got her well on the way to a diagnosis. So your vets did nothing like this so far, but it sounds like it is what you will do next from your post. Like you, I'd want to "isolate" the problem to some area and then try and figure out what it is.
 
Thanks for all of your suggestions. I will get the vet to do some more tests, maybe blocking his back if he thinks it would be useful and see how we go.

Id just hate for it to keep getting worse until he can't walk
