Lamella Wedge & other nasties.
Now THIS is Lamella wedge!!! No Frog, No Hoof, No Horse I found this photo on this facebook site. It’s the only photo of lamella wedge I have seen. I’m not a member but I was able to read it anyway. It’s Ove Lind’s site. Many people seem to not like this guy but he certainly has cut a lot of cadaver hooves up to see what’s inside. There is a lot more info in the various sections. He had a different take on how to solve ‘distal decent’ or thin soles. He says to get the weight off the walls altogether & let them sort themselves out. He maintains that the ground is pushing the walls up which distorts the inner structures & gives the appearance of P3 dropping or sinking. By relieving the pressure on the walls, it allows the top of the walls (the coronet) to drop down the bone tower a bit, (because a ‘bit’ is all it has tho drop) He said a horse with thick soles can’t have it but he wasn’t so clear about how the horse gets thin soles to start with. He does say that some horses have flat P3 with no dishing anyway so impossible to create a hoof with concavity. Which makes sense to me. But what came first the flat bone or the flat sole?? 
Also I was very interested in the position of what I suspect is toe callous or the ridge of sole under the tip of P3. When I conpared it to my photos of Sonny's toe callous they are in different positions. This requires further investigation I think. But it has been really good to find this lamella wedge photo which is so clear. His website is www.SwedishHoofSchool.com His webshop is www.SlowFeeding.com & has a very good looking set of slow feeder hay nets. www.GoodHoofCare.com There was a link to Pete Ramey's site so I looked at it in relation to what Ove was on about http://hoofrehab.com/ Near the top of the middle column is a link to a power point presentation which Pete says is a BIG file. Yes it is, but ok for anyone on broadband. I also went through this presentation with a fine tooth comb, going over & over each slide. It was good to see the various views of each hoof right under each other in rows. Easy to make comparisons. However the presentation has some problems in it that make it hard to read & I had to keep backing up the slides because they went through way too fast. I took copious notes & many screen prints for reference. What I’m learning is that Sonny’s feet weren’t all that bad to start with & I was probably led astray a bit regarding the need to do a cetain trim. It’s obvious that he had far better feet at the beginning of my ‘barefoot trim journey’ than he has now. So once I get this infection problem under control I will be aiming at getting his feet back to where they were before & leaving it at that. But that doesn’t mean I haven’t learned a hellova lot along the way.

Re: Lamella Wedge & other nasties."He had a different take on how to solve ‘distal decent’ or thin soles. He says to get the weight off the walls altogether & let them sort themselves out."(This is the same thing that Pete Ramey says.) "He does say that some horses have flat P3 with no dishing anyway so impossible to create a hoof with concavity. Which makes sense to me." I could be wrong and you DIDN'T mean that 'horses have flat P3' from BIRTH. But, if I understood correctly, and he means flat p3 from birth...This (above statement) makes no sense to me. I have never heard of a horse being born with a P3 that is incapable of performing correctly. It would be the way the horse is raised that causes various pathologies; not an inherent inadequacy of the bone. Sure, P3 can subsequently be damaged and that would impair the hoof's ability to restore itself even if the horse one day is given appropriate care. Going back to the shape of P3, have you held in your hand a 3- dimensional P3? The entire ventral surface is concave! So how can flat soles be a result of a 'flat' P3? (unless the P3 has been severely deteriorated; which again is not from birth) Here's a good coffin bone video that shows how the ventral surface of the coffin bone is concave. Only the outer/bottom 'lip' touches the table, the rest is lifted off/vaulted. It is the sinking due to laminitis to whatever degree that brings the various parts of the hoof down to the ground and thus squishes the hoof's sole flat down to the ground. The sole thickness is thus compromised; it can 'afford to be.' (obviously still not without negative consequence!!!) With continued inadequate care, yes the coffin bone will dissolve into a flatter shape. Then, depending on the degree, full recovery to a concave state is impossible. http://www.youtube.com/watch?v=gNa6K8TTY7E |

do you have radiographs of your horse's feet showing that the coffin bone is fully intact? is he rotated at all?
edit: nevermind I see the radiographs! |

What did you think Erin about his xrays? Did you read the vet's comments I put in blue? re the flat soles referred to in my above post:- My comment was "But what came first the flat bone or the flat sole??"
So I agree with you Erin, it's hard to know at what point the horse's P3 goes flat. Take Sonny's xrays as an example. Vet said the bone still looked ok although he noted they appeared to be flattish. So at that point his feet had lost their shape for about a year. Would that have been enough time to make the P3 flat or was the P3 going flat anyway. It's like chicken & egg.
Anyway I was really chuffed to find this photo of the lamella wedge to be able to see for sure what the inside should look like. It would be really hard to just imagine & hope you didn't cut right into the live tissue at tip of P3 by taking too much off. But if you don't take enough off you don't fix anythin. That's where I was at wondering just how much to remove. I was also very interested in the position of the toe callous in relation to the length of the lamella wedge. I wish I could find several more photos on that topic for comparison. One photo does not a library make.

This is a great article about long toes. The xray image is very interesting not only because it supports the article but because the P3 is actually past parallel which I found extrodinary. "These horses tend to 'stand under themselves' with their hind feet, meaning that at rest the foot is placed further forward than normal in relation to the vertical axis of the limb and the main mass of the hind quarter, giving the horse a sickle-hocked appearance." Armed with that information, the research team set out to determine if long toes could be a cause of gluteal pain in horses (the muscles that run along the back of a horse's hindquarters on either side of the tail), and if corrective trimming and/or shoeing could correct the problem and eliminate the pain. The article goes on to explain about the average length of breakover of the group of evaluation horses before & after corrective trimming. Mansmann explained that most horses in need of a hind end evaluation will display behavioral problems including not performing as expected, not being willing to move off the leg, or stopping at jumps. He also noted that these horses might display signs of a sore back. Additionally, "any horse where their hind foot coronet is slanted such that an extended line (following the coronary band line) hits them behind the elbows should be evaluated," he said. Very interesting article. |
