COW: Quarter Crack Repair

This is a collection of images showing how I like to repair quarter cracks. Quarter cracks appear in the hoof, usually as a resulf of too much heal compression, causing the quarter to bulge out. The repetitive loading and unloading of the foot, causes a crack to form at the point of the bulge. It can be challenging to get these cracks stopped because of the repetitive motion they sustain. Consequently the best strategy is to 'lace' them up. This repair method is one of the best ways to stabilize the crack so that it can grow out. Here is how it is done.

This picture is of the hoof at the start of the repair. The crack has been cleaned out with a small rotary burr. It is very important to get these thoroughly cleaned.

Here apposing eye hooks have been placed on each side of the crack.

The next step is to weave wire in between the eye hooks, lacing it up much like a shoe lace. This provides a very strong, stable repair. Also note, that an antiseptic wax has been placed in deep crevice of the crack.

Once the wire is placed, the 'eye' portion of the eye hooks is cut off. The remaining stem is peaned over to hold the wire firmly in place.

Finally, the patch is covered and held together with a hoof adhesive.
