CT features and lesion prevalence in competing Thoroughbreds are unknown.<\/jats:p>\n <\/jats:sec>\n \n Objectives<\/jats:title>\n To identify standing CT features within the MC\/TPJ of elite Thoroughbred staying racehorses.<\/jats:p>\n <\/jats:sec>\n \n Study Design<\/jats:title>\n Retrospective cohort study.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n \n Computed tomography scans of the\n MC<\/jats:styled-content>\n \/\n TPJ<\/jats:styled-content>\n were performed as part of pre\u2010race screening for fracture risk and graded for\n CT<\/jats:styled-content>\n features. Descriptive statistics and univariable logistic regression models were generated to investigate associations with presence of palmar osteochondral disease (\n POD<\/jats:styled-content>\n ), parasagittal groove subchondral lysis and fissure.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n A total of 406 limbs from 86 horses were scanned; 72 horses were scanned once, 12 horses were scanned twice, and two horses scanned three times.\n POD<\/jats:styled-content>\n was common, being present in 74\/86 (86.0%, 95%\n CI<\/jats:styled-content>\n 76.9\u201392.6) horses and in 231\/342 (67.5%, 95%\n CI<\/jats:styled-content>\n 62.3\u201372.5) limbs on first scan.\n POD<\/jats:styled-content>\n was associated with more career race starts (\n p<\/jats:italic>\n \u2009=\u20090.05) but fewer placings per start (\n p<\/jats:italic>\n \u2009=\u20090.008). Parasagittal groove (\n PSG<\/jats:styled-content>\n ) lysis, previously associated with condylar fracture, was observed in 16\/86 (18.6%; 95%\n CI<\/jats:styled-content>\n 11.0\u201328.4) horses and 20\/342 (5.8%; 95%\n CI<\/jats:styled-content>\n 3.6\u20138.9) limbs on the first scan, whereas fissures in this region, which are not associated with fracture, were observed in 41\/86 (47.7%; 95%\n CI<\/jats:styled-content>\n 36.8\u201358.7) horses and 65\/342 (19.0%; 95%\n CI<\/jats:styled-content>\n 15.0\u201323.6) limbs. Osteoarthritis of the fetlock joint was uncommon.\n <\/jats:p>\n <\/jats:sec>\n \n Main Limitations<\/jats:title>\n \n Horses travelling from overseas had undergone prior screening of their fetlock joints, predominantly with\n MRI<\/jats:styled-content>\n , likely reducing the prevalence of pathology in these horses.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n \n POD<\/jats:styled-content>\n is common in elite staying Thoroughbred racehorses, however, negatively impacts performance. The prevalence of\n PSG<\/jats:styled-content>\n lysis supports the use of\n CT<\/jats:styled-content>\n screening of high\u2010risk populations of Thoroughbred racehorses in fracture risk management.
