I just looked up in my book about "lamness" the word "founder" of course it says to see "laminitis" the definition it gives for Laminitis is as follows
Laminitis:Painful foot condition in which the blood supply to the hoof wall is interupted, and the hoof wall - pedal bone bond breaks down; founder.
When you go to the section on Laminitis it goes into a great deal of explanation about the process and the different ways it can occur.
In short the condition beings with a reduced blood flow to the "sensitive Laminae" of hoof wall. This then results in cell death and the breakdown of the bond between the hoof wall and the pedal bone.
They seperate Laminitis into 2 different categories 1.) acute and 2.) chronic
Acute is the active stage - within the first 72 hours of the disease and then Chronic laminitis is characterized as persistent changes in the hof wall structures and the blood supply which results from the disruption or interuption of that blood supply.
This book also gives a list of different types of contributing factors that can cause the reduced blood flow to the foot.
It is a very interesting book with lots of information about all sorts of illnesses and different lamnesses.
It talks about the digital pulses and how to locate and find them, how to tell if your locating it and other reasons why the digital pulse may be interuppted etc. This book discusses treatments, signs and symptoms, relieving pain, different types of shoeing options and what the shoes do and how they effect the hoof. It goes into detail with the chronic form of laminitis and also shows pic of x-rays etc. Discussion of the management of Chronic laminitis is discussed, but with every horse ...just as humans certain things work well on one but not as great on another.
I think this is such an important part of horse lamness research! It really was something I started readin about a lot when Barbaro was injured in the Kentucky Derby a few years ago. Much time and effeorts and research has now been dedicated to this issue that con happen to anyones horse....but there are many ways to prevent this from becoming an issue.
I hope this helps...
It just breaks my heart when laminitis / founder becomes an issue for a horse...
If there was anything in the horse world that I wish I could wave a wand over and have more insight, and research done on it would be Laminitis....
