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.

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.
