Vertical wall cracks that usually don't result in lameness are described as which thickness?

• A. They can be partial thickness or full thickness
• B. They are always full thickness
• C. They are always partial thickness
• D. They have no thickness classification

Answer: (A)

Vertical wall cracks vary in how deep they run. The hoof wall is made of multiple layers, so a crack that only affects the outer, non-sensitive layers is considered partial thickness, while a crack that goes through the full wall thickness to the sensitive tissues is full thickness. Since these cracks often don’t reach the sensitive structures, they usually don’t cause lameness. This depth distinction guides treatment: shallow, partial-thickness cracks can be trimmed, cleaned, and sealed, while full-thickness cracks require more thorough debridement and stabilization to prevent infection and pain.
