These techniques are particularly advantageous for patients with increased anesthetic risk or financial limitations. To the authors\u2019 knowledge, the removal of osteochondral fragments from the distal interphalangeal joint in a standing, sedated horse using small-diameter arthroscopic equipment has not been previously reported. Case Presentation: A 7-year-old American Quarter Horse\u2013Thoroughbred cross presented on referral for treatment of osteochondral fragmentation in the right fore distal interphalangeal joint. A standing arthroscopic approach to the distal interphalangeal joint was performed. In a weight-bearing position, debridement of the dorsal osteochondral fragments from the second and third phalanx was successfully completed, using a 2 mm NanoNeedle scope and 3.2 mm high-flow 10- degree cannula (Arthrex\u00ae). At one year follow-up, the horse had returned to competition and was sound at veterinary examination. Conclusion: This case demonstrates the feasibility of standing NanoNeedle arthroscopy of the equine coffin joint with improved maneuverability, surgical ergonomics, and reduced iatrogenic injury compared to a standard rigid arthroscope. The successful execution of this technique effectively expands our collection of standing arthroscopic procedures in the equine patient.<\/jats:p>","DOI":"10.3390\/ani16081168","type":"journal-article","created":{"date-parts":[[2026,4,10]],"date-time":"2026-04-10T13:16:17Z","timestamp":1775826977000},"page":"1168","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Standing NanoNeedle Arthroscopy of the Distal Interphalangeal Joint for Removal of Osteochondral Fragments of Distal P2 and the Extensor Process in a Horse"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-5504-5550","authenticated-orcid":false,"given":"Nicole A.
