Nanoscopic evaluation to facilitate treatment of the proximal interphalangeal joint following a traumatic wound in a 4‐month‐old colt

Abstract A 4‐month‐old Irish Draught colt was presented for treatment of a traumatic wound to the right hind pastern region of 6 hours’ duration. Investigation confirmed communication between the wound and the proximal interphalangeal joint. Due to the joint's small size, a traditional synovial endoscopic lavage could not be performed. Therefore, a needle arthroscope (Nanocope, Arthrex) was utilised to lavage the joint under general anaesthesia. The needle arthroscope allowed visualisation of the articular surface, higher ingress lavage (compared to needles), as well as assessment for potential foreign bodies. Following surgical treatment and a course of oxytetracycline, the foal returned to soundness. The wound healed without complication. Use of needle synovial endoscopy has therapeutic potential in future cases of septic synovitis in small joints that do not allow entry of a traditional synovial endoscope.
