A new and powerful concept for equine laminitis
How the laminae become damaged in equine laminitis has never been established, the dorsal wall lifting theory for the first time proposes a viable explanation for laminal failure. We already know that laminitic hooves distort, but no consideration has been given to why and when distortion starts or its consequences on the laminal structures. I am proposing that abnormal hoof growth commences before all evidence of pain or discomfort. That after several days of abnormal hoof growth, the changes in hoof shape will be enough to traumatise the underlying laminal bond. At this stage hoof capsule distortion will not be visible and will only become apparent several months later. This lack of understanding the role of hoof distortion has hampered our progress in understanding laminitis and its treatment.
In short – the laminae are a victim of hoof capsule distortion.
...hoof distortion is not the result of laminitis, it's the cause. Tom Ryan FWCF
The Dorsal Wall Lifting model for equine laminitis states that abnormal hoof growth induces hoof capsule distortion in the developmental phase. As the hoof capsule distorts, it induces pain in the underlying laminal bond, signaling the start of the acute phase. The severity of a particular laminitis case will depend on the shape and strength of the hoof capsule, the stronger the hoof the more severe the case. (Click here for a quick overview of this theory)
The idea that the dermal laminae are being destroyed by hoof capsule distortion has never been considered before. The factors known to cause laminitis may be altering the way hoof is grown and not directly insulting the dermal laminae.
