Summary
# Editorial Summary: The Lamellar Wedge Chronic laminitis in horses results in a characteristic pathological horn structure within the lamellar region—the lamellar wedge—which fundamentally compromises normal biomechanics of the foot and significantly impairs the animal's capacity to return to work. Collins and colleagues examine the aetiological mechanisms driving wedge formation, recognising that this abnormal tissue develops as a consequence of disrupted lamellar integrity and altered weight-bearing forces during the acute and subacute phases of laminitis. Understanding precisely how and why the lamellar wedge develops is critical for farriers, veterinarians and rehabilitation specialists to tailor effective supportive foot management strategies during both the acute crisis and the long recovery phase. The clinical implication is substantial: interventions specifically designed to prevent or minimise wedge formation—whether through targeted hoof care protocols, appropriate therapeutic shoeing, or carefully managed rehabilitation—may fundamentally improve functional outcomes and prognosis in affected horses. This work underscores that managing chronic laminitis effectively requires more than controlling pain and inflammation; it demands proactive mechanical management aimed at the structural integrity of the lamellar apparatus itself.

Practical Takeaways
- •Recognition of lamellar wedge pathology should inform your foot management strategy in chronic laminitis cases, as it directly impacts functional recovery
- •Farriers and veterinarians should work together on preventive foot care approaches, as managing the development of this structure before it fully forms may improve prognosis
- •Understanding how lamellar wedge affects foot mechanics is critical for setting realistic performance expectations and recovery timelines with horse owners
Key Findings
- •Lamellar wedge is an abnormal horn structure that develops in the lamellar region during chronic laminitis in horses
- •Lamellar wedge adversely affects normal foot function and compromises return to previous performance levels
- •Understanding the pathologic process of lamellar wedge formation is essential for appropriate supportive foot management
- •Prevention or reduction of lamellar wedge formation may improve clinical outcomes in laminitis cases
