Wow! How interesting!

Skeletal atavism is an inherited throwback to an earlier evolutionary stage. It's often found in shetlands and miniatures, usually affecting the ulna and/or fibula.
Here's the radius and ulna of a miniature horse with dwarfism compared with that of a Thoroughbred (not to scale... but you knew that). The olecranon is the point of elbow, so we're looking at the upper foreleg from elbow to knee.
From the UC Davis's Veterinary Genetics website: "Horses with skeletal atavism typically display short legs, a low rectangular shape body, narrowing at the knees, clubfoot, and impaired movement. The angles of the legs and pattern of movement progressively worsen as the foal ages..."

While experienced farriers are worth their weight in gold as far as being a part of a team keeping your horse sound, sometimes they need help. As miraculous as it seems to be able to visualize from external cues what is going on inside the foot, they do not, in fact, have X-rays vision. This is where your veterinary team can come in handy evaluating and monitoring progress with what is actually happening inside of a foot, and that can have so many implications and effects on your horse’s soundness.
The images here are excellent examples of getting as close to perfect balance through the joint spaces with appropriate palmar angles of th coffin bone, all of which sets the foot and soft tissues associated with the lower limb to not be over worked. If there is too much toe or shoe in front of the point of balance, there is excess leverage created on the lamina of the hoof and the tendons and ligaments of the lower limb are stretched too much, like a rubber band that has been stretched too much and no longer has appropriate elasticity.
The amazing thing is that horses are awesome at healing, if these issues in the foot are addressed, unless there is significant damage and injury, the soft tissues can also recover with appropriate rehabilitation and treatments.

Why is defining an ideal model for hoofcare so challenging?

In hoofcare, many approaches are closely tied to philosophy, training lineage, or personal success stories. That makes it difficult to agree on the most basic goals for our hoofcare work.

The horse is not a collection of parts to be managed independently, but a complex, adaptive system—physical, neurological, emotional, and environmental factors constantly interacting and reorganizing in response to load, stress, and experience. The hoof reflects this complexity rather than existing apart from it. Posture, movement, behavior, and hoof form are all expressions of how the whole system is coping in that moment.

Which makes it difficult to be objective and scientific about the outcome of our day-to-day decisions for the horse.

An ideal model doesn’t replace professional judgment—it sharpens it. At ISIH, we use a model for the horse's hoof based on supporting the whole horse and structural integration with gravity.

Our Ideal Hoof Model isn’t based on opinion, tradition, or geography—it’s based on patterns that repeat across horses, disciplines, and environments worldwide. By studying and documenting a large, diverse database of horses that consistently demonstrate square posture, functional movement, and long-term stability, the same hoof characteristics show up again and again.

That’s the key. When a model holds true across climates, footing types, workloads, and breeds, it stops being a theory and starts becoming a reliable reference. The ideal hoof isn’t something we force onto the horse—it’s something the horse creates when load is balanced, posture is supported, and the system is allowed to organize efficiently. That’s why this model works globally: it’s grounded in how horses function on the most basic biological level.

Without a defined model, how do we objectively evaluate whether our decisions are helping the horse—or just aligning with our preferences?
