Project Dexter results so far

Project Dexter is our research project into rehabilitation of horses with "navicular", caudal hoof pain, DDFT/collateral liagment injuries.

Every horse who comes to Rockley with these diagnoses is included in the project, which runs entirely due to the help, goodwill and support of Prof. Peter Clegg at Liverpool and numerous horse-owners and their vets, to whom I am eternally grateful! Horses are assessed by their own vets, and 10 different (and sceptical!) vets have been involved so far.

The preliminary results for Project Dexter are shown below. The research project started in February 2008, with Dexter and horses are listed chronologically.

As at June 2010, 13 horses are included - 10 have completed their rehab, 3 are ongoing. 8 out of 10 horses are in full work, including jumping and hunting; 1 horse returned to light work; 1 horse (which had severe bone damage) improved but did not return to full work. 7 out of 10 horses have been re-assessed by their referring vet, confirming the improvement or return to soundness.

I have had to shrink the table to fit it onto the blog - if anyone is interested in the full details, please email me: nic@rockleyfarm.co.uk and I will send you a copy.

Frankie update

Frankie goes home this week - he is a French TB ex-racer who arrived following MRI with a diagnosis of DDFT, DSIL and collateral sesamoidean ligament damage.

Although he is only a young horse, he is a completely laid-back TB with perfect manners :-) Unfortunately he does have an under-developed digital cushion, probably originating from the fact that he would have been shod at 2 yrs old. His feet have improved a lot, but aren't as good as they would have been if they had been allowed to fully strengthen before they were shod.

His video footage is up here: http://www.vimeo.com/12913304

RF June 2010

Lexus 19th March 2010

Two pieces of good news for a Thursday - its turning into a wonderful week ;-)

Firstly, Lexus went home yesterday, and I've uploaded his footage which is here: http://www.vimeo.com/12796301

There aren't many horses who would be given a second chance barefoot by their owners having gone lame at 19, but Lexus is one of the lucky ones, and I have to say he deserves it - he is an absolute gent.

We don't have a magic wand at Rockley, so we can't turn the clock back and get rid of 19 years of wear and tear, but we can help horses improve their feet, and boy was Lex keen to improve his! Its lovely to see his footage now, and watch a short-striding, toe first landing horse transformed into a heel first landing, big-striding horse :-) Lex still finds hard uneven ground a struggle, but he picks his way and copes admirably. Across the fields and on good ground he looks half his age.

Now for the second bit of good news :-)

Some of you may remember Paul, who was with us for rehab over last winter. There is more info about him and links to his film footage in the "Rehab horses" tab at the top of the page (scroll down to the bottom to see him) and on here:

http://rockleyfarm.blogspot.com/2010/02/comparisons-paul-before-and-after.html

http://rockleyfarm.blogspot.com/2010/01/paul-again-just-for-completeness.html

http://rockleyfarm.blogspot.com/2009/12/good-job-paul.html

He went home in February and yesterday was the day his vet came to see him for the first time since he was lame at the end of last year.

Paul is one of the horses in "Project Dexter", and as part of that, we ask that the horse's own vet assesses its lameness before coming down here and again following rehab so that we have an objective record (often from a sceptical vet) of whether the horse has improved. Sometimes horses are re-vetted down here, or immediately after they go home; on other occasions the vet visits the horse once its been home a few months.

When I went to see Paul last month he was looking magnificent, and he is working 6 days per week, but its always a slightly nerve-wracking wait to see if the vet (in this case Ollie Crowe at Willesley Equine Clinic) agrees. The fantastic news though is that Paul trotted up completely sound and passed with flying colours.

Before he came here, he was 3/10 lame LF on a straight line and 4/10 on a circle, so thats quite an improvement :-)

More pages, more horse info

I am a bit slow on the uptake with the old technology, though swapping to a Mac has helped no end, but its taken me till now to work out that you can have extra info on yer blog...I only realised because I saw some other blogs which had nifty additional pages across the top, but it took a couple of days before I mastered how you put them there.... :-0

So now, there are some handy little tabs at the top of the blog where I've put info about our own horses and the rehab horses, so that if you come across a name you can check out the horse's potted history, plus pics and links to film clips. I've only put up details about a selected few past rehabs at the moment, but will add to the list as we go along - I hope you find it interesting!

Its summer...and a Lexus update

For the first time in 2 years we are having a real summer - blue skies and warm weather day after day - its hard to believe but its happening (!)...I would start worrying about water shortages normally, as the ground is now so dry, but with Wimbledon and Glastonbury both running over the next 2 weeks, surely we are guaranteed some rain?

Today was Lexus' day, however, and after a very busy weekend, with owners here both days and Lady going home, we decided that Monday morning was a good time for him to have a special trip out.

Lex not only came here with a lameness problem but was also a reluctant traveller. True to his gentlemanly nature, he would load willingly, only to start crashing about and being generally very unhappy once in motion. Luckily, this was easily solved by travelling him in our big trailer with no partitions, so he could spread his weight and shift about if he felt unsteady.

Today definitely a grand day out for Lex, as we and Chris, his owner, decided to box him, Jacko and Felix to a different part of Exmoor for a ride Andy and I had never done. Lex travelled perfectly, and so we set off on a spectacular ride which took us out along the cliffs near Lynton. The sea was flat calm and Caribbean blue, and although Jacko once or twice thought about spooking on the narrow paths, his sense of self-preservation fortunately stopped him from throwing himself down a sheer 300ft cliff (!). Felix and Lex of course behaved as if it was a walk in the park...

Lex finished the 2 hr ride in fine form, despite having had to deal with some very stony tracks, and boxed just as calmly back here, so all in all an extremely successful day.

Storm update - the photos

Storm's left front after 4 weeks

Storm's left front on arrival a month ago

I posted Storm's footage here on Friday: http://rockleyfarm.blogspot.com/2010/06/storm-update.html and both his owner and I think he has made progress over the last month.

Over the weekend, I took photos of his hooves, and it became much clearer just why he is landing better - his caudal hoof has beefed up (technical term ;-) considerably, particularly the frog.

What you can't see from this photo is that his frog is now actively weightbearing; when he arrived, when you laid a rasp across his hoof the frog was well below his heel buttress but now heel buttress and frog are almost level.

Its very ironic that some of the typical treatments for his type of condition (a serious DDFT lesion) try to relieve the caudal hoof, whereas in fact with these injuries the caudal hoof is always weak, under-utilised and desperately needs to strengthen...More on that tomorrow!

Storm update

Storm's owner came up today, so that we could film him and see whether he had made progress over the 4 weeks that he has been here.

I've updated his footage and its below, and I've uploaded it here in high definition as well. We think he has improved - see if you agree...(!)

Horsefly heaven...

Its happened, we have the most fabulous weather here at the moment (I am enjoying it now, but will start to get twitchy about running out of water if it goes on for more than another week or so...perverse I know!), and the horseflies have arrived.

Poor Felix was absolutely mobbed by them last night and the little blighters have obviously hatched out in huge numbers - the more you kill the more there seem to be, and to add insult to injury they've added humans to their "to eat" list already...

As always, I've been taken by surprise, even though I know this happens every June, and so am off to search the UKNHCP forum for the most effective horsefly repellent, and then stocking up in large quantities...

Artists' impression...

As part of their course, the UKNHCP students were revising their anatomy today, and how better to test it than by drawing it onto a horse...

There was a certain amount of artistic licence, and revision was eventually halted by us running out of paint..Still, if I ever need a horse to be an extra in the next Dances With Wolves film - or to go trick-or-treating on at Halloween - at least I know who to use ;-)

The anatomy of a barefoot horse...!

I'm running a course for UKNHCP students this week and as part of that I was updating the course material. I was going through THE anatomy book on the horse's hoof - "The Equine Distal Limb" by Jean-Marie Denoix, for the hoof anoraks amongst you - when I realised there was something odd about some of the photos.

The book is incredibly well illustrated with photos of hooves and limbs at every possible stage of dissection and with reference images from MRI and ultrasound , with every anatomical structure clearly labelled.

The odd thing comes in the initial photos of the hoof, in the basic cross-sections. The hoof is shown half dissected, so that you can see the inner and outer structures, but along with the outer hoof capsule, the shoe has also been carefully cut in half (left on the hoof of course). Even more bizarrely, the shoe is numbered and labelled as another part of the hoof(!).

Initially I thought this was a one-off, then I realised it crops up routinely, and that where the outer hoof wall is shown, there is a shoe attached. The numbering for each illustration states: 1, Distal phalanx, 2, Ungular cartilage, 3, Corium limbi...9, Hoof wall, 10, Sole, 11, Skin, 12, Shoe - and don't forget this isn't a shoeing book, its a reference manual for functional anatomy...

Its as if a medical text book listed the parts of the human body and then went on: gloves, hat, shirt, trousers - but of course that would be unthinkable(!)...

Its a great illustration of something that Sarah and I wrote in Feet First, bemoaning the dearth of research on barefoot - that vets and academics "concentrate on looking at how hooves function with metal shoes, almost as if it would be unthinkable to assess bare hooves".

It also illustrates the massive mental block built into the teaching system which vets, more than most of us, have to overcome.

More from Horse & Hound!

Well, here's an astonishing bit of news for a Friday - and its not even April 1st! This week's Horse & Hound have published the letter I wrote in response to their "Do horses slip barefoot?" query, and you could have knocked me down with a feather - in fact I told people on the UKNHCP forum that I would eat my rasp (Sarah's expression!) if it was published...so there are now plans to find me a toffee rasp... :-)

I was surprised and pleased in equal measure, and all credit to them for publishing. I had to smile though, because accompanying the letter is the editor's comment that (of course!) not all horses can cope barefoot, and that it must be lovely to save £70 per set on shoes(!)...I haven't the heart to break the news that there is a little bit more to having barefoot horses which are capable of season after season and hundreds of miles over Exmoor than simply not bothering to book a farrier ;-)

In my original letter I also offered to lend their showing commentator a horse for a days' hunting, if she was interested in finding out what horses can cope with out of shoes. It was edited out of the magazine, understandably, but I still hope she might take me up on the offer. The only problem is that according to her column, again in this week's H&H, she wouldn't be confident on an unshod horse over any but the most perfect going, so I suspect Exmoor, with its selection of rocks, bogs, 1 in 3 gradients and granite wouldn't really appeal... She might also be a bit shocked if she saw the footage on this post(!): http://rockleyfarm.blogspot.com/2010/06/some-horses-dont-need-studs.html

Lady's progress

Lady hasn't had many updates so far, mostly because she has progressed so quickly! She is a great little mare who was diagnosed with lesions to the DDFT following MRI and I've put details up about her before here http://rockleyfarm.blogspot.com/2010/05/loading-how-shoes-affect-even-good.html and here http://rockleyfarm.blogspot.com/2010/05/sometimes-its-complicated.html.

To my great delight, she has been a second Paul - one of those horses who makes very rapid progress, to the joy of me and her owners!

She is also a very pretty mare, and definitely plays Ginger Rogers to Felix's Fred Astaire - he adores her(!)... These lovely photos were taken by her family when they came up to visit and show her at her best, on a very happy day.

What we do, and what we don't do...

I'm not entirely sure whether its a good thing or not, but Rockley is being mentioned a fair bit on T'internet at the moment. I keep half an eye on it, and although I obviously can't monitor everything, generally it seems to be interest in, or positive comments about, the research programme or people wondering whether we can help their horses or owners giving updates about horses who have been here - all of which are great.

Now and again, however, I see people making statements about what we do or don't do, or about our facilities, or about horses who have been here. I'll make it plain, that unless statements are coming from me or from the horse's owner, then they should be taken with a pinch of salt as they are quite likely to be untrue ;-) So, to set things straight:

• If you have a horse who has been diagnosed with navicular, DDFT or collateral ligament damage or other soft tissue damage within the hoof, then the best option (if you are after more info about rehabilitation) is to email me via www.rockleyfarm.co.uk If you send X-rays/MRIs/photos that can be helpful too.
• For rehabilitation, we take horses with the problems listed above or who have hoof issues such as poor medio-lateral balance. Usually these horses have been diagnosed on the basis of nerve-blocks to the caudal hoof or pedal bone. Typically (but of course there are no guarantees) we can improve soundness over about 3 months - some horses are quicker and some are slower, thats just a very rough guide.
• I will not normally take horses for rehabilitation if their problem is primarily a metabolic disorder, such as chronic laminitis, insulin resistance, Cushings etc. Its not because you can't help horses like this - far from it, as dietary changes can make huge improvements. However, it wouldn't be appropriate, or professional, for me to have those sorts of horses here because even if they do well at Rockley, they will be back to square one at home. Far more effective for the owner to keep the horse at home and make the necessary changes there.
• By contrast, "navicular" horses and those with the types of injuries listed above respond extremely well to a short period of rehab over the surfaces we have at Rockley. We aim to kick-start improvements to the hoof, and get the horse to the point where it is back in its normal level of work and happy on the terrain it will encounter at home (whether that is roads, tracks etc). From then on, owners can usually carry on successfully without needing the sorts of conformable surfaces we have here. Thats because, once the correct biomechanics are solidly in place, the horse tends to stay on a "virtuous circle" of improvement.
• The only people who train at Rockley are UKNHCP students and practitioners. Anyone else who says they have "trained" here is being a bit naughty, to say the least - they may well have visited but unless they are listed on www.uknhcp.org.uk they are not one of our practitioners and may have little or no training. I don't run courses here other than for UKNHCP members and never have ;-)
• Finally, horses coming here for rehab need to come on vet referral. I don't mind in the least if a vet is sceptical - the best ones usually are, initially! In those cases I normally speak to them and explain what we do and we agree a timescale by which we need to see improvement in the horse.

Hope thats helped to clear things up! Normal service will resume tomorrow ;-)

Some horses don't need studs...

One of the common questions about barefoot is how you cope without studs. In fact (ironically!) in the same edition of Horse and Hound which I talked about here: http://rockleyfarm.blogspot.com/2010/05/horse-and-hound-verifies-barefoot.html there was a comment by a showing judge who was worried about unshod horses being more prone to slipping on grass than shod horses.

Lots of us (including me) wrote to H&H confirming that we've not found barefoot horses more prone to slipping - in fact often the opposite - but for anyone who still isn't sure despite all the evidence from sound barefoot horses, here is Felix's video from last week - of course all the horses who went round shod had studs in, but despite that he beat all but 2 of them ;-)

Ghost's video

I've uploaded the video footage Sam took of Ghost on Friday here, because its too big to post directly onto the blog: http://www.vimeo.com/12344074

Hope it does the job for a grey Monday morning!

What do you do with a 25 yr old "navicular" horse?

...take him XC, of course ;-)

We had a belter of a day at the EFH hunter trial today - gorgeous weather, horses on top form, and Ghost back being the centre of attention, with everyone marvelling at him - just as he likes it :-)

Sam took some fun footage of him and Felix which I will upload next week, but for now, the photo says it all!

Mooching on the track...!

Eight o'clock last night...the equine equivalent of taking some beers down to the beach with the boys? ;-)
