This is a roping horse with canker, who had sloughed the digital cushion in three hooves.
We have included photo collages of all three affected hooves.
Treatment started 1-28-2004
The focus photos are of the back right hoof, which was in the worst condition.
Day 1 - Applied Lacerium to the front left and rear right feet. We also applied Lacerum II to the front right foot. The back
right foot appeared to be in worse condition than the others. The rear left foot appeared to be unaffected.

The owner had been treating this horse since November with Formaldehyde and 10% Iodine, Bleach, and other Caustic
agents. The surface tissue was dead and dry but the tissue sloughed out 1 1/2 inches into the digital cushion.

The areas were debrided except on the right front hoof and wound wash and gel were applied to the right rear and left
front.  Lacerium II was applied to the right front.  

Day 4 - All treated hooves had formed a new granulation bed. The granulation bed was more extensive in the left front
and the right rear.  Note : Left front and right rear had a black pigment present with bad odor that was 1/8th of an inch
thick. (Suggest presence of Proteus)

Also present is a yellow rim of ossified Lateral Cartilage.

The right rear hoof had a creamy odoriferous material that was not present in the others.  

We debrided the dead and blackened tissue on the hooves and found good granulation beds on the front left and the back
right hooves. The granulation bed on the front right hoof was not as good but present.  The back left hoof still appears

Right Rear Hoof
Day 11 - Four days after our last treatment; the bandages had come off of left front and right rear allowing the
wound surface to become dryer.  After washing with wound wash, the developing granulation bed was healthy.  
The right rear hoof appeared to possibly have a betahemaletic strep
infection.  There was no evidence of new growth of black pigment on the granulation surface. There did appear to
be new penetrating cracks between the sole layers, these were cut out and medicated. There was no odor present
on any of the three feet.  The horse was reshod with
queen's plate shoes and in order to get to a depth on the frog surface, a large amount of the heel was removed. The
treatment at this point was a mixture of RemX and Lacerum I plus activator.   
Day 15 - Versalon Gauze packed into wound sites with Platelet Derived Growth Factors applied. Lacerum
Ointment was applied around the edges. The hooves were then wrapped and this process was repeated every
third day.

18 Months later, the canker has not returned. This horse returned to full performance level, and he and the
owner won a saddle and $8,000 after the horse was treated.
