Summary

# Editorial Summary Hoof conformation fundamentally influences limb biomechanics and injury risk, yet the specific morphometric parameters that predispose horses to lameness remain incompletely characterised. Mata and colleagues examined 73 horses across three activity types (show jumping, dressage, and riding school) to establish associations between lameness presence and two key measurements: dorsal hoof wall angle (DHWA) and coronet band circumference (CBC). Their logistic regression analysis revealed that lameness risk increases in two distinct conformational patterns—either acute DHWA combined with enlarged CBC, or conversely, more upright feet (larger DHWA) paired with smaller CBC—suggesting that hoof balance exists within a relatively narrow optimal window. Show jumping and dressage horses demonstrated significantly higher lameness prevalence than riding school horses, and the authors propose that maintaining a DHWA of approximately 50 degrees supports proper hoof-pastern axis alignment and reduces injury risk in these disciplines. For practitioners, these findings underscore the importance of regular hoof assessments and timely podiatric intervention, as systematic monitoring of DHWA and CBC may prove instrumental in preventing lameness, particularly in competition horses where biomechanical demands are greatest.

Practical Takeaways

•Monitor hoof morphometry regularly in performance horses, especially those in dressage and show jumping, as specific conformation patterns predict lameness risk
•Maintain a target dorsal hoof wall angle of approximately 50 degrees with balanced coronet band circumference through consistent, evidence-based trimming and shoeing protocols
•Schedule regular podiatric interventions as preventive maintenance rather than waiting for lameness to develop, particularly when abnormal hoof-pastern axis alignment is detected

Key Findings

•Horses with acute dorsal hoof wall angle (DHWA) combined with large coronet band circumference (CBC) showed higher lameness probability
•Horses with upright feet (larger DHWA) and smaller CBC also demonstrated increased lameness risk
•Show jumping and dressage horses exhibited higher lameness prevalence than riding school horses
•An aligned hoof-pastern axis with DHWA around 50 degrees may be protective against lameness development
