| This model of laminitis is based on the proposal that
the triggering events known to cause laminitis do not act directly on
the laminae but instead cause the heel region of the hoof capsule
to grow quicker than normal. When horn grows at different rates it will
curve in the direction of the slower growing horn, in
laminitis towards the toe, so faster growth at each heel will cause the
hoof capsule to distort in the toe area, eventually distortion advances
to a point when it exerts a pulling force B (extension)
onto the laminae at the toe which will traumatise and damage the
underlying laminae. The distortion process peels away the dorsal hoof
wall from the distal phalanx (pedal
bone). In other words, damage to the laminae is
directly the result of hoof capsule distortion.

A Compression at the
coronary band, B Dorsal hoof wall is peeled from the distal
phalanx (pedal bone), C Sole is pulled upwards onto the distal
border of the distal phalanx. |

This interpretation of the role of the hoof capsule in laminitis
offers new opportunities for treatment of this condition. Presently I'm trying to
minimise the distortion process early in the laminitis cycle by cutting deep
vertical grooves into the hoof wall.
This procedure is not painful and many grooved animals soon show a reduction
in pain levels, when implemented at a very early stage hoof capsule
distortion is also minimised. This procedure should not be implemented
without full veterinary approval.
Abnormal hoof growth has previously been associated with the chronic
phase of laminitis. It seems that the question of when
abnormal hoof growth commences has never been asked before.
All this is explained in greater detail on these pages.
