Summary
# Editorial Summary Digital flexor tendon sheath (DFTS) pathologies represent a significant diagnostic challenge despite their frequency in equine practice, with lesions affecting both fore- and hindlimbs and outcomes heavily dependent on accurate early identification. Tannahill's 2021 review synthesises the clinically relevant anatomy of the DFTS alongside practical guidance on diagnostic anaesthesia techniques and their interpretation, whilst detailing the characteristic imaging findings associated with the primary DFTS conditions encountered in practice. The article emphasises that practitioners with a solid grasp of the complex anatomical relationships within the digital flexor apparatus can substantially improve their confidence and accuracy when interpreting diagnostic blocks and imaging modalities at the stable side. Beyond standard diagnostic protocols, the author provides practical strategies and interpretive tips designed to maximise diagnostic yield without requiring advanced imaging facilities. For farriers, veterinarians, and allied equine professionals, this work serves as an accessible reference for systematically approaching DFTS cases, bridging the gap between anatomical knowledge and clinical application to facilitate earlier intervention and improved case outcomes.
