From a frog to a prince

As I posted earlier in the week, rehab is all about growing a healthier foot. I also posted last week about how important the back of the foot is in maintaining soundness - its a very, very common place for injuries to occur.
Most of the horses who come here for rehab have a lameness which blocks to this area and on MRI have tendon and ligament damage within the hoof capsule. Externally these horses have weak frogs, under-run heels, collapsed digital cushions and unbalanced feet and as a result they typically land toe first rather than heel first on a flat, hard surface. 
Step forward Alfie, who had most of these issues although his feet had already started improving in the few weeks he was out of shoes before he came to Rockley. Nevertheless, they weren't attractive feet as you can see from his original photos. 

Rehab of feet like these has to start at the back of the foot because this where the injuries have occurred and its the source of pain for the horse. Improve the health of the back of the foot and the horse can start move more comfortably, allowing injured tissue to heal and strengthening a previously  weak foot. 
Alfie's foot today looks a lot different. This is due to a combination of factors but essentially a healthier frog has allowed him to rebuild the back of his foot resulting in a better landing, longer stride and improved soundness. 
One of the biggest problems with improving frog health occurs when you have (as Alfie did) a deep central sulcus split in his frog (sometimes known as a sheared heel). You can just about see the line in this photo as it extends from his frog and divides his digital cushion. 

Splits like this are painful and can be enough to stop a horse landing heel first. They are also a source of infection and are very, very persistent. 
Generally a combination of a topical treatment (at the moment I favour manuka honey) and a better landing improve splits sufficiently for the horse to change to a heel first landing but I have known horses where the damage to the digital cushion was so deep-rooted that they never fully healed. 
These photos show the progression fairly clearly - when he arrived Alfie had a thick pad of frog which quickly shed as he started doing more mileage on his bare feet. 
A few weeks in the frog is rebuilding and his heels are also becoming less contracted. 
Today he has the outline of a much stronger frog which still has some development to go. You can also see from these shots the much greater depth at the back of his foot (indicated by the deeper collateral grooves either side of the frog) which are a clear sign of a foot becoming stronger. 
This foot also had a central sulcus split which, with hindsight, is visible on day 1 but which was concealed by the thick pad of frog which overlay it when he arrived. Now we are getting on top of it but we are lagging a little behind with this foot, although not for much longer I hope!
Its always interesting looking at feet from this angle because the changes in wall height and digital cushion depth are much more obvious this way. Compare the distances from hairline to hoof wall, for example, and then the distance from the top of the hoof wall to ground level, bearing in mind that this foot is only about halfway through growing a stronger hoof capsule and there will be an equal amount of improvement still to come.

Growing a healthier hoof

Rehab is all about taking an unhealthy hoof and improving it. This is quicker and easier without a shoe on the foot and that's the main reason the horses here are barefoot - its about hoof health, pure and simple. 
Bruno arrived here 12 weeks ago with weak, contracted frogs and was of course landing toe first because his palmar hoof wasn't strong enough to support him. He was just out of shoes on arrival and photos show a hoof which is compromised.
His feet today are starting to look more like functioning hooves. His palmar hoof is becoming stronger and that starts with a healthier frog and more supportive heel and digital cushion. 
 As you can see from this angle, the frog is much stronger, more centred in the foot and the digital cushion is developing too. Rather than the heels being long and under-run they are very slowly coming back as the palmar foot is gaining strength.

Looking at the lower photo you can see that there is a steeper angle of new growth immediately below the hairline. This is clear at the toe but the improved growth is also happening at the back of the foot. This is why the hoof pastern axis is better in the more recent photo. 
Bruno's hoof looks pretty strange right now as the stronger hoof capsule is not yet at ground level. The trick with a photo like this is to project an imaginary line which continues the angle of the new growth to the ground; this gives you a clearer idea of where the new hoof capsule will be.

In Bruno's case the toe will be shorter, the foot less under-run and the palmar hoof more supportive.
As with the other foot the biggest change here is to his frog. His heels and bars, which had folded over, are much stronger and his foot is beginning to develop some much-needed concavity. 
Lots of other things need to happen as well, not least a shorter toe and the heels becoming less under-run, but a healthier frog is the essential first step.
This foot was nowhere near as weak as his other but there were still balance issues and its nice to see the foot becoming more evenly loaded.

14.2hh Dales gelding with fantastic feet

Quick blog post for Freya, who is staying with us at the moment as her Dales pony (who is also here at the moment) is looking for a new home - he is for sale or loan with view to buy and can be seen and tried here.
"Yartleton Liquorice 14.2 9 yr old Dales Gelding (Section B) is looking for a new home. 

Always cheerful and pleased to see you, marches straight into the lorry and is really enjoying his first season hunting with the EFH, great over all terrain and loves watching hounds. 

Snaffle mouthed, good in traffic and not a spooky character. 

Would ideally like a home where he could continue to hunt or do something equally as fun. Barefoot with great feet. Home more important than price."

Louie's first 4 weeks

Louie has been here nearly 4 weeks and as Karen came to visit him last weekend we are overdue a photo update. He arrived in shoes and with his main problem being a toe first landing and a nasty central sulcus infection which was worst in his RF.
This is his better foot and as you can see out of shoes he has been in a hurry to start using his frogs and strengthening his palmar hoof. Its less contracted and he is already landing heel first which is great. The long to you can see in the lower photo is his old hoof and he will soon shorten that of his own accord now that he is landing better. 
Apologies for the mud but we had just got back from exercising when I took these photos. Although the split hasn't healed yet his improved landing has made for a much healthier frog and digital cushion.

Its also interesting I think to compare the hoof wall which was fairly unbalanced and long in the initial photo. A healthy hoof has fairly short walls which should be wider at ground level than at the hairline (so level or sloping slightly outward when viewed from this angle).
 

Louie's LF had a better frog from the start  - unfortunately I don't have a photo of him shod but despite the slightly muddy photo I took immediately after his shoe came off you can see that the frog and sole are more robust today. 


Again, there are changes to the hoof wall and digital cushion visible from this angle. Although this foot was not so distorted or as compromised as the LF there are still areas where he needs to grow a stronger foot. In particular I would expect his digital cushion to beef up even more now he is landing heel first.

The most important part of the hoof

This is a quick post but an essential one because its all about the most important part of the hoof - the back of it. 

This is the part of the hoof on which the horse lands. Its provides crucial shock-absorption and its health is fundamental to soundness and good movement. The back of the foot is where most lameness problems originate simply because its such an important structure and once its compromised the horse is vulnerable to tendon and ligament damage, abscesses and even bone damage. 
So contrast the feet on these 2 horses - clear examples of a healthy versus unhealthy foot. Your eye is drawn to the hairline - diving downwards and indicating the collapsed frog and digital cushion on the horse below but level and strong on the horse in the top picture.
Although both horses are unshod the horse in the lower photo had been shod at an early age and up until a few weeks before this photo was taken. As a result of his weak planar hoof his hoof/pastern axis is poor - after all if the back of your foot is collapsing its hard to stand up straight.
This is always a telling angle for assessing and observing hooves. It tells you almost everything you need to know not only about how healthy or otherwise the back of the foot is but also about the media-lateral balance of the foot. 
The upper photo shows a 2 year old horse who isn't in work but his foot is balanced. He has a sound digital cushion and lands well and this will become even stronger as he matures and comes into work.

The lower photo is a different story - unbalanced, collapsed feet with vanishingly small, contracted frogs and of course a toe first landing and media-lateral imbalance. 

Its my experience that shoes seriously and in some cases irrevocably weaken the back of the foot not only because they remove stimulus from the frog (and hence digital cushion) but also because they restrict the essential expansion and contraction of the hoof.

I have many photos of horses where the back of the foot becomes healthier out of shoes and I'll post a follow-up of today's photos shortly.

However, despite the widely-held myth that shoes "support" hooves I've never seen a series of photos showing a frog and digital cushion becoming healthier in shoes. Maybe they exist but I very much doubt it...

Goofy's 10 week update

Goofy's update is a bit overdue but I've had a very busy start to the year and I'm not as up to speed with the blog as I should be - apologies.
As ever his original photos are at the top and his latest are the lower of each set. As you can see, the biggest changes are in his frogs and in the concavity in his feet - from flat soles with no depth to much more functional feet with reasonable collateral groove depth.
This is important because collateral groove depth is a good indicator of how capable the foot is of working on tough ground and shock-absorbing. 

This angle provides a good demonstration of how the frog and digital cushion have developed. In the initial photos the digital cushion is rather pinched and distorted but 10 weeks later its much stronger. 

This is his worse foot and it has as well as a weak frog a central sulcus split which is improving but still apparent. 

His bars are also changing a lot - he has less than half a good foot at the moment so there is a lot of improvement still to come. 
From this perspective you can clearly see the angle change which marks the difference between the old and new hoof capsule. 
The old abscess hole which you can just make out in the initial photo is now halfway down his hoof capsule and clearly marks the rate of hoof growth.
An improving picture - but a way to go till his feet are as good as they can be.
