A new and powerful concept for equine laminitis
One frequently over-looked aspect of laminitis is abnormal hoof growth, but recently hoof growth has been attracting a lot more interest. In his PhD thesis Ramzi Al-Agele(1) observed while conducting in vitro experiments on horn producing keratin cells extracted from different areas of equine coronary band tissue, that cells from the quarter region divided more rapidly when exposed to higher levels of insulin, while the same cells from the front of the hoof were not affected in the same way.
Combining Ramzi Al-Agele’s observations with a greater understanding of equine metabolic syndrome (EMS) which is known to have an undefined relationship with laminitis, raises an interesting possibility, could EMS be affecting how the hoof capsule grows?
...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.
In short – the laminae are innocent victims of abnormal hoof growth which causes hoof capsule distortion.
