Summary
# Editorial Summary: The Pathophysiology of Developmental and Acute Laminitis Hood's comprehensive review examines the underlying mechanisms of both developmental laminitis (the subclinical phase preceding clinical signs) and acute laminitis (the rapid onset inflammatory stage), acknowledging substantial progress in understanding this condition whilst highlighting persistent knowledge gaps. By synthesising current evidence on the pathophysiological processes involved, the author illustrates why prevention and early intervention remain challenging: the developmental phase produces no observable clinical symptoms, creating a critical window during which tissue damage progresses undetected, whilst the acute phase itself is characterised by a compressed timeframe that limits diagnostic opportunity. The primary implication for equine professionals is the necessity of understanding these disease mechanisms to develop more targeted preventive strategies, as conventional reactive treatments struggle once clinical signs emerge. Importantly, Hood emphasises that subacute and chronic laminitis—the longer-term sequelae following acute episodes—will continue to present significant management challenges regardless of acute-phase interventions, underscoring why addressing the earliest pathophysiological changes remains paramount. For farriers, veterinarians, and nutritionists particularly, this underscores the importance of identifying and modifying risk factors during the developmental phase, before irreversible laminar damage occurs.

Practical Takeaways
- •Improved understanding of laminitis mechanisms will lead to better preventive and therapeutic strategies, ultimately reducing laminitis impact
- •The asymptomatic developmental phase presents a significant clinical challenge—focus on risk factor management and monitoring in susceptible horses
- •Subacute and chronic laminitis management will remain problematic without earlier detection methods; long-term case management strategies are essential for practice planning
Key Findings
- •Knowledge of developmental and acute laminitis pathophysiology remains incomplete despite advances in understanding
- •Developmental phase of laminitis lacks clinical symptoms, making early detection difficult
- •Acute phase of laminitis is short in duration, limiting intervention opportunities
- •Subacute and chronic laminitis sequelae are likely to remain major clinical problems due to diagnostic and timing challenges
