Explain the developmental phase? |
Time from the triggering event until the
evidence of pain, varies but don't know why. |
The time from the triggering event, which
starts hoof capsule distortion, until the time when hoof capsule distortion
causes pain. Duration of the developmental phase is dependent on
the shape, strength and rate of horn growth at the heels. The
faster the heels are growing and the stronger the hoof capsule,
the more severe the case will be. |
|
Why is it the laminae in
the toe are mostly damaged while heel laminae generally stays
intact? |
Err... got me there! |
Hoof capsule
distortion is primarily in the toe region, where the laminae
are oriented in the same direction as the hoof capsule is
distorting. |
|
Why is it that Cobs, Arabs and Warmblood types
seem to suffer more severe laminitis, foundering more frequently? |
They are good doers! |
They have stronger hooves which can exert
greater force onto the laminae and are less tolerant to rapid
heel growth (can't
dissipate). The hoof wall in these cases can
be 'popped' off the distal phalanx. See
No laminar wedge.

|
Why do some pedal bones sink and others rotate? |
Sinkers just have worse cases of
laminitis. |
Round hooves distort more generally which
damages a larger area of laminal bond leading to sinking, while
long narrow hooves
distort mostly in the toe causing the pedal bone to rotate. |
|
Why can some ponies be very fat but not get
laminitis? |
Don't really know why. |
Their heels may not have started to grow
faster yet (not laminitic) or the heels are growing faster but they have weak flaring
dissipating heels, so it's not so painful (potentially
laminitic). |
