  • Back to reality – equine systemic proteoglycan accumulation

    image

    There’s been a bit of a quiet patch on the site with no new articles for a while. The Mighty Hobo came temporarily out of retirement and I pared down all other activities to spend as much time with him as I had, and we loved every minute that we got to spend doing our favourite thing. Below is the last jumping round we ever did, two months ago now. If you look carefully you can see he has too much extension in his fetlocks, indicating too much ligament laxity – subsequently confirmed as Equine Systemic Proteoglycan Acculumation (ESPA, also known as Degenerative Suspensory Ligament Desmitis). He is also losing his jump a little but this is hard to spot if you’re unfamiliar as he tries so very hard. He was immediately re-retired and is currently enjoying (OK hating) some time with his pony in the field where we hope to keep him comfortable enough for a little while longer. 

    The little buck through the finish isn’t resistance or pain, it’s because I allowed him to lock on to the wrong final fence – he’s a professional so he only bickers with me once he’s got us over the jump. Hobo pretty much only jumped clear rounds and I never carried a whip. The freeze frames below make the hyperflexion issue a little easier to see as his fetlocks hit the deck even in canter (as opposed to take off or landing, where it is not so abnormal). Apologies that the video is not great quality due to it’s circumstantial nature.

    Below is a video of a comparative, unridden canter & trot in the field over a year ago but with hindsight already a little suspect.

    Ultrasonic evaluation of suspensory ligaments can confirm or rule out lesions or degeneration,

    and it is usually the suspensory ligaments that fail first. The main reason, though, for the change of name to ESPA is that it is a systemic disorder so all connective tissues may be affected, including the ligaments, tendons, heart and eyes (e.g. Halper et al., 2006). These horses will not improve, we do not currently have a way to stop or reverse proteoglycan accumulation, they can only be managed in their deterioration until the time comes for euthanasia. It appears to be hereditary, so breeding must be avoided, although it is no longer thought to be restricted to certain breeds. Symptoms may become apparent from birth and Hobo was lucky to manage his condition for as long as he did, given that we didn’t even realise what we were up against. 

    With my boy on his way out I’m planning to throw myself into some more articles, videos and demos and would be very happy to hear your requests. We currently have a few series to continue including rider exercises, the equine back, and horse gear and gadgets. There may also be the odd mention of the glamorous Mr Remus (below) who is doing his best to step up, but they’ll never be another Hobo, and the Hobo updates end here.

  • Hobo update: can the mighty have fallen?

    An update on Hobo, since my last piece on my grieving over him. I know that many are waiting for the next biomechanics piece, but right now all I really think about is Hobo. In truth my boy did not cope with retirement and neither did I. He was bored, angry, frustrated, and causing a lot of trouble in the field. So in March I began the painstaking process of bringing him back into work and trying to keep him sound or at least produce either a lameness that was manageable and still allowed him some stimulation, or a prognosis so clear that a tough decision could be made.

    I brought him back into work thinking I was signing his death warrant and to start with every time he shoved his head into the bridle I cried. However with a lot of work and obsessive monitoring he became sound, pretty much stayed sound, managed to return to hacking and a little jumping, and became a relaxed, happy horse once more. He was a little intermittent and I was very cautious, but underneath I allowed my little hopes to soar again. Out came my favourite phrase: nothing is difficult because the steps are so small. He attended a clinic in April (clip below), where Blyth Tait declared him “probably the best five year old in the country”. Hobo’s 12, but I didn’t correct him; everyone likes a compliment. He went back into the ring (video also below), just over little jumps, because subconsciously I’m still saving him for some glorious future. Excuse the videos’ brevity & quality, my cameraman is 11.

    A couple of weeks later, in May, Hobo developed a serious hoof crack when the ground suddenly hardened and I was reluctant to push him in case an altered movement affected his ability to cope with everything else, so he was back on holiday. That break cost me 3 rugs and a fence, and his waistline ballooned dramatically in only a couple of months. He came back into work last week and we’ve had to switch from the fat girth to the ridiculous.

    At the same time there was a lump. A little lump on his shoulder that had done nothing all his life began to grow in about February this year. Nobody likes lumps, and I certainly don’t like change. Whilst Hobo was already against the odds I pretty much ignored it, and pulled out my second favourite phrase: not the crocodile nearest the boat. A couple of different vets passed through, had a look and we all agreed to ignore it together. We ignored it for months but it didn’t go away. In defiance of my dismissal it has continued to grow, now rapidly. It’s on the shoulder of the leg that has caused all the trouble, the leg with the tight tendon, with the sore navicular bone, with the giant splint, with the serious hoof crack, and these things are not unrelated. Once one part of a linkage causes a limitation other parts must compensate and will eventually struggle or even break down, particularly in a horse that doesn’t do rest, even under sedation.

    On Monday Hobo had his annual vaccination and a terrible reaction has made me worry that his immune system is already struggling. He and I have decided that we are ready. Tomorrow morning (Friday) he will go under the knife and we will see what is there, how long he has, and if there’s anything else that can be done.
