Skeletal forelimb measurements and hoof spread in relation to asymmetry in the bilateral forelimb of horses.

Summary

# Editorial Summary Skeletal asymmetries are commonplace in horses, yet we understand relatively little about how the hoof structure might adapt to compensate for these imbalances between the two forelimbs. Wilson and colleagues investigated whether hoof spread (the medio-lateral flexibility and deformation of the hoof wall during loading) varies systematically in relation to skeletal measurements and asymmetry, hypothesising that the hoof acts as a dynamic compensation mechanism. Their analysis revealed correlations between specific skeletal measurements, bilateral differences in forelimb anatomy, and asymmetric hoof spread patterns—suggesting that hooves on the more asymmetric side may indeed spread differently as an adaptive response. These findings carry significant implications for practice: recognising that hoof asymmetry may reflect underlying skeletal compensation rather than pathology alone could influence how farriers approach trimming and shoeing strategies, and might inform veterinary and physiotherapy assessment of horses presenting with unilateral lameness or abnormal wear patterns. Understanding these relationships could help practitioners work with rather than against the horse's compensatory mechanisms when managing bilateral forelimb asymmetry.
