Which term best describes a long-standing form of laminitis?

• A. Chronic laminitis
• B. Acute laminitis
• C. Inflammatory laminitis
• D. Non-inflammatory laminitis

Answer: (A)

Chronic laminitis describes a disease course that lasts for an extended period after the initial event. When the acute crisis passes but the hoof laminae have suffered lasting damage, the condition is classified as chronic. This phase is marked by persistent lameness and clear structural changes to the hoof, such as coffin bone rotation or sinking, hoof wall deformities, and long-lasting changes in hoof growth. These changes reflect remodeling and ongoing instability of the distal phalanx within the hoof capsule, which can persist for weeks to months and may lead to founder in severe cases.

The other terms don’t fit the scenario of a long-standing form. Acute laminitis denotes a rapid-onset, severe episode that requires urgent management. Inflammatory laminitis emphasizes active inflammation as the defining feature, which is more about the process than the duration. Non-inflammatory laminitis would misrepresent the typical disease process, since inflammation is commonly involved.
