Which term describes a crack that traverses the hoof wall?

• A. Toe crack
• B. White line crack
• C. Sole crack
• D. Wall fissure

Answer: (D)

A crack that traverses the hoof wall is called a wall fissure. The term specifically describes a crack that runs through the thickness of the hoof wall itself, not just at a particular region or along a boundary. Toe cracks are localized to the toe portion of the wall, white line cracks occur at the junction between the wall and sole along the white line, and sole cracks occur in the sole beneath the wall. So when the crack crosses through the wall, wall fissure is the correct description.
