Summary
# Editorial Summary Understanding how the tarsal joint moves in three dimensions has traditionally required invasive bone-pin implants, restricting such analyses to controlled laboratory settings where the horse's natural movement may be compromised. Khumsap, Lanovaz and Clayton investigated whether non-invasive skin-mounted markers could reliably capture the complex 3D motion of the equine tarsus, comparing kinematic data obtained through surface markers against the gold standard of bone-pin tracking. Their findings demonstrated that carefully positioned skin markers can accurately represent tarsal joint mechanics, opening the possibility for kinematic research in clinical and field-based environments where invasive techniques are impractical. This has important implications for practitioners seeking evidence-based understanding of hock function during lameness investigations, rehabilitation monitoring and performance assessment—work that can now potentially be conducted without surgical marker placement. For farriers, veterinarians and physiotherapists managing tarsal pathology, the validation of non-invasive kinematic methods provides a pathway towards more detailed biomechanical insights into individual cases and herd-level movement patterns.
