Welcome

All current theories for equine laminitis are based on an unknown insult arriving at the lamina tissues via the blood supply. This concept is challenged on these pages, instead it is proposed that hoof distortion starts earlier than was previously thought, before all evidence of pain. The main proposal is that hoof distortion alone is capable of damaging the previously normal laminae.

A model of early hoof distortion is the basis of the Dorsal Wall Lifting Theory of laminitis. It offers a new insight on laminitis which offers a better understanding what is really happening within the laminitic hoof.

If hoof distortion is responsible for damaging the laminar bond, this is good news for the laminitic equine because the hoof is an external structure and is available for procedures that could minimise any adverse effects of distortion on the underlying laminae, like the grooving procedure on the right.

Practical experience with this model for equine laminitis since 1998, has been very positive, the grooving procedure has been used on over 250 cases, all cases being veterinary referrals form vets in my area, as I will not consider grooving a hoof without veterinary approval.

By inserting a groove on each side of the toe, pain levels have been reduced and the progression of the condition has hopefully been impeded in approximately 80% of cases.

This theory reconciles many of the inconsistencies seen in laminitis, but there is a long way before this model can be scientifically accepted.
