Can the cannon bone rotate? The skull is a bone. Can it rotate? Bones articulate at their joints during movement, but never at any other time.
With a laminitic horse there cannot be — nor is there — rotation of the coffin bone. We have always been taught that the coffin bone in a laminitic horse rotates downward, and our concept of shoeing the laminitic horse is based on that idea: to support the bony column in an attempt to stabilize the so-called rotation.
Bones don’t rotate, but the hoof capsule can be displaced and thereafter distort (Figure 1). Mike Wildenstein, FWCF hons, CJF, the resident farrier at Cornell University’s School of Veterinary Medicine, first introduced me to this concept of upward displacement of the hoof capsule. At that time, I could not or would not allow my mind to fully grasp the concept. It went against everything I had ever been taught or read. I did extensive research and found little or no information to support this theory. Since I love to think outside the box, I began to reason it out logically. Interestingly, it took a very…
