Areas of abnormal uptake were assessed using a previously validated grading system.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Eight fractures were located in the parasagittal groove (PSG) (six lateral and two medial) and six fractures were located abaxial to the PSG (non\u2010PSG) through the palmar\/plantar condyle (all lateral). All horses in the latter group had uptake in the lateral palmar condyle of the contralateral limb suggestive of stress remodeling. Three horses with PSG fractures had uptake in a similar location in the contralateral limb. Horses with lateral condylar fracture only presented minimal or mild uptake in the medial condyle, which is considered atypical in the front limbs for horses in full training. Four horses developed periarticular uptake in the postoperative period suggestive of degenerative joint disease, three of these horses had persistent uptake at the fracture site. These four horses did not return to racing successfully.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The findings of this study provide evidence of pre\u2010existing lesions and specific uptake patterns in racehorses suffering from metacarpal\/metatarsal condylar fractures.<\/jats:p><\/jats:sec><jats:sec><jats:title>Clinical significance<\/jats:title><jats:p>PET has a possible role in the prevention, diagnosis, and postoperative monitoring of metacarpal\/metatarsal condylar fractures in racehorses.<\/jats:p><\/jats:sec>","DOI":"10.1111\/vsu.14031","type":"journal-article","created":{"date-parts":[[2023,9,21]],"date-time":"2023-09-21T12:01:15Z","timestamp":1695297675000},"page":"131-142","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Positron emission tomography assessment of metacarpal\/metatarsal condylar fractures post surgical repair: Prospective study in 14 racehorses"],"prefix":"10.1111","volume":"53","author":[{"given":"Thomas C.","family":"Bergstrom","sequence":"first","affiliation":[{"name":"William R.
