1 Introduction Bone fractures commonly occur in Thoroughbred racehorses and can result in euthanasia. The global incidence of such catastrophic fractures is around 1 per 1000 horse starts (Wright et al. 2024), but this can vary depending on the jurisdiction, race type, track surface and reporting criteria (Wright et al. 2024). Fracture is the leading cause of euthanasia on the racecourse (Wright et al. 2024) accounting for approximately 75% of all racecourse fatalities (Rosanowski et al. 2018).
