HISA has identified key risk factors for fatal proximal forelimb fractures in racehorses, according to an Equine Health Advisory released Monday. The findings highlight previously underrecognized dangers for horses in early training stages or those returning from extended layoffs.
The advisory, based on data collected through the HISA Portal, reveals that fatal proximal forelimb fractures accounted for 15% of all training fatalities reported to regulatory veterinarians in 2024.
Perhaps most concerning, more than 40% of horses that suffered these catastrophic injuries had no recorded high-speed furlongs within the 60 days prior to the incident.
Analysis shows affected horses averaged just 12.3 high-speed furlongs in the two months preceding their injuries. Horses specifically with humeral fractures logged even fewer — only 5.9 high-speed furlongs during the same timeframe.
“It is HISA’s goal to substantially reduce the number of these fatalities beginning in 2025,” said Dr. Jennifer Durenberger, HISA Director of Equine Safety and Welfare. “Building awareness is the first step. This advisory reflects our commitment to data-driven safety and highlights the collective responsibility we have as an industry to intercede for at-risk horses before injuries occur.”
The comprehensive advisory has been distributed to all trainers and veterinarians registered in the HISA Portal. Industry professionals can access the full document through the Resources section at www.hisaus.org.
HISA officials emphasized that translating this growing body of information into actionable guidance represents a critical step toward making the sport safer for all participants.
The findings suggest that gradual conditioning and careful monitoring of horses returning to training may be essential in preventing these catastrophic injuries that have significant welfare implications for the industry.
