This study looked at yearling radiographic reports of 8,660 Australian thoroughbreds to determine the number and type of common radiographic lesions that occur in Australian yearlings, and what impact these lesions might have on future athletic performance.

We found experienced veterinarians are very consistently detecting radiographic lesions, with 97.1% agreement in the detection/non-detection of lesions in our study. We report extensive data demonstrating the frequency and types of radiographic lesions in yearlings, and the impact of those lesions on future athletic performance. To date, this is the largest cohort study to be conducted.

Our research allows for improved understanding of the possible impact a wide variety of radiographic lesions may have on yearlings’ future athletic performance. This information will improve industry confidence relating to lesion interpretation and allow for better management and long-term welfare of these yearlings.
