Summary
# Editorial Summary Flexor tendon injuries remain a leading cause of lameness and lost training time in performance horses, yet conventional B-mode ultrasonography often fails to detect the early microstructural damage that precedes clinical tendinopathy. This literature review synthesises recent imaging advances to evaluate how emerging ultrasonographic techniques—particularly elastography, acoustoelastography, and ultrasound tissue characterisation—might identify subclinical tendon pathology before visible lesions develop at the metacarpal or metatarsal level. Beyond traditional greyscale imaging, these novel modalities assess tissue mechanical properties and structural organisation, offering potential to shift clinical practice towards prevention rather than reactive management of flexor tendon disease. For practitioners involved in performance horse care, understanding the capabilities and limitations of these developing technologies is increasingly important, as early detection of vulnerable tendons could meaningfully reduce re-injury rates and improve long-term soundness. As these techniques progress from research application towards wider clinical availability, farriers, veterinarians, and conditioning professionals should anticipate changes in how tendon screening and monitoring protocols are approached in high-demand horses.

Practical Takeaways
- •B-mode ultrasound remains your primary tool for tendon assessment, but emerging techniques like elastography may soon allow earlier detection of problem tendons before they fail clinically
- •Catch subclinical damage early: new imaging methods could help identify micro-damage from ageing and repetitive strain before horses show lameness, potentially preventing career-ending injuries
- •Stay informed about advancing ultrasound technology in your region—elastography and tissue characterisation techniques are moving from research into clinical practice and may become standard diagnostic tools
Key Findings
- •B-mode ultrasonography remains the most commonly utilised technique for detecting and monitoring tendon lesions at the metacarpal/metatarsal level in horses
- •Recent research emphasis has shifted toward identifying subclinical tendon damage before clinical tendinopathy develops to prevent further injury
- •Elastography, acoustoelastography, and ultrasound tissue characterisation show promising results for equine flexor tendon imaging
- •New imaging modalities may change clinical approaches to equine flexor tendon assessment as development continues
