A new and powerful concept for equine laminitis

How the laminae become damaged in equine laminitis has never been established. We already know that laminitic hooves become visibly distorted after time, but no consideration has been given to why and when distortion starts or its impact on the laminal structures.

It’s likely that abnormal hoof growth at the quarters commences during the development phase and the resulting changes in hoof shape will traumatise the underlying laminal bond at the dorsal hoof wall. 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 innocent victims of abnormal hoof growth which causes 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. More >

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.
