Case Study - Ribbo
This horse had a lameness in his right front leg that improved each time he was rested in his stall, but just a little exercise brought back the limp. When I examined him he was markedly worse when turned to the right, so I anesthetized the nerve that went to just the outside part of his foot (a nerve block that lasts for about two hours). Ribbo went completely sound in about 5 minutes so I knew his pain came from the outside part of his foot.
I then concentrated on taking multiple xrays of the outside parts of his hoof. The radiographs showed he had fractured the lateral wing of his coffin bone very close to the joint.

I elected to apply fiberglass casts to his foot and keep him from exercising on it. I changed his cast every 4 or 5 weeks and trimmed his foot each time.
The casts conformed very well to his foot and gave a very rigid support as can be seen by the imprint in these removed casts. I took radiographs every other cast change to evaluate any healing.

The separation in the coffin bone was not so clear each time so it was healing. We started casting in March and removed the last cast in late July when we could no longer see a fracture line. In his third cast Ribbo once broke out of his stall and ran around the farm. His owner said he never took a "bad step", and was sound the days after his romp. It attests to the strenght of the fiberglass casting material.
Two months after the last cast was removed Ribbo was back in full work getting ready for a Preliminary Horse Trial.
