Abstract
The results of arthroscopic surgery in the treatment of osteochondral fragmentation of the proximodorsal aspect of the first phalanx and the influence of other fetlock joint lesions on prognosis were evaluated in 336 horses. Horses were classified as: 1) returning to previous use at the same or higher class of performance; 2) returning to previous use (regardless of class of performance); or 3) failing to return to p revious use. Ninety-six horses (29%) had fragmentation alone; 140 hors es (42%) had fragmentation and additional. fetlock lesions, and 100 ho rses (29%) underwent concurrent carpal arthroscopy. Of the 100 horses that underwent carpal arthroscopy, 63 had proximodorsal first phalanx fragmentation alone and 37 had other fetlock lesions associated with t he fragment. There was significant association between lesion type and return to previous use for the Thoroughbred racehorse group. There wa s also a significant association between lesion type and return to the same or higher class of racing for the Thoroughbred racehorse group. No significant association in return to previous use existed for raceh orses vs. nonracehorses, Thoroughbred racehorses vs. Quarter Horse rac ehorses, single vs. multiple joint involvement, and single vs multiple fragmentation per joint. The Thoroughbred racehorses in this study we re sensitive to additional fetlock or carpal lesions, as was exemplifi ed by the significant effect lesion type had on outcome.
