Chronic laminitis: strategic hoof wall resection.

This study discusses a method for treating chronic laminitis, a severe foot condition in horses, by partially removing the upper part of the hoof wall to reverse damage caused by inflammation and tissue compression. It emphasizes the importance of careful monitoring and management to ensure successful recovery and growth of new, healthy tissues.

Introduction

• Chronic laminitis is a serious disease that affects the hooves of horses. It is characterized by soft-tissue compression and compromised circulation within the hoof, which can lead to osteitis (bone inflammation) and sepsis (a serious blood infection).
• Additionally, this condition can induce coronary corium (the tissue layer that generates the hoof wall) to swell, drain, or separate from the hoof capsule within about eight weeks of the onset of laminitis.

Pathology and Consequences

• Slow-onset cases of this condition can induce soft-tissue impingement, often secondary to displacement of the distal phalanx (the bone within the hoof) due to a lack of attachment of the hoof wall.
• In both presentations of laminitis- fast-onset and slow-onset- the common treatment is partial resection, or surgical removal, of the upper hoof wall. This process aims to reverse the compression and vascular impingement caused by the hoof capsule.

Treatment and Recovery

• If the pathology of the disease is not too severe, the area from which the hoof wall was resected can heal, or reepithelialize, and grow new, attached tubular horn (the hard outer covering of the hoof).
• The paper emphasizes the importance of rigorous aftercare for the affected horse. This involves using firm bandages on the healing area and restricting the horse’s exercise until the new tubular horn has fully regrown. This aids in the recovery process and helps in the development of a strong, healthy hoof.
