Hmm - not sure I agree with Ute. The ground surface of the pedal bone
is
covered in solar corium which produces the sole horn in a downward
and
forward direction. (The upper surface of the pedal bone and
lateral
cartilages are covered with a laminar corium which produces
the laminar
horn). Bowker has postulated a role for the bar corium in
solar horn
production but the extent of this is not yet fully
established. It isn't
correct however to say the bars produce the sole.
If the pedal bone rests
on the solar corium (all round as in sinking,
or at the toe as in classic
founder) it causes bruising of the highly
vascular solar corium and over
time can cause pressure necrosis -
tissue death.
The sole follows the
shape of the ground surface of the pedal bone and
it is this which gives it
concavity. Because the pedal bone is very
light it is can erode with
unphysiological pressure; if it lacks a
good suspension within the hoof
capsule or the sole cannot draw flat
on weightbearing, the concave surface
can wear flat. When the bone has
lost its concavity the sole also loses its
concavity.
However, sometimes when there is inadequate movement for the
sole to
exfoliate, the sole becomes very full and 'flat' in appearance.
Too
full a sole can inhibit hoof mechanism.
