The photos shown present
a technique used by Swiss farrier Aaron Gygax while he was
working at Rood & Riddle’s Equine Podiatry Clinic (~2004
thru early 08). It is one of several techniques that can be
successfully used to stabilize a crack and pre-supposes the
crack is dry and no longer weeping or suppurating. This
technique does not require the farrier to drill holes in the
hoof wall in cases where the hoof wall is compromised & may
not support the loads imposed by a conventional lacing
process.

Non-Penetrating Method
-- Bolster applied to wall |
Hoof with original quarter crack repair shown.
-- Crack is dry & not weeping or suppurating.
Start with braided Spectra or Poly-Vectran fabric and pieces
of stainless welding rod or bar (~ 1/16 inch dia)
Saturate the fabric with standard acrylic adhesive, fold
over the bar and apply to one side of the crack..
Stretch wrap the fabric bolster to hold it in place while
the acrylic adhesive cures. Repeat this process to build a
similar bolster on the other side of the crack. The foot can
be placed on the ground during this cure period.
Remove the stretch wrap. You now have two “bolsters” that
will distribute the suture tensile load over a large surface
area on either side of the crack. In addition, you will
drill holes for lacing behind & under the metal rod &
bolster. The hoof wall is NOT penetrated.
Drill holes for the lacing sutures. A 1/16 inch diameter
drill will be suitable. No risk to hoof wall.
Insert the suture wires using the backing plates.
Secure the sutures with a backing plate. It is not necessary
to over-tighten as the wires are twisted in the center like
a turn-buckle for accurate tension control.

turnbuckle for accurate tension control
Once the sutures are accurately tightened, fill the center
of the repair area between the bolsters to encapsulate the
wires. A simple mixture of acrylic & fibers will secure the
repair.
At the same time you are filling the center of the repair,
apply a saturated layer of repair fabric to add strength. –
CobraSox braid is shown here --Kevlar- Carbon Fiber.
Apply multiple layers of stretch-wrap over the repair to
secure the work and accelerate the acrylic adhesive cure.
The acrylic adhesive is radiolucent and will allow
radiographs to document the suture positioning.
