Summary
Lateral condylar fractures of the third metacarpal and metatarsal bones represent the leading cause of fatal injury in UK racehorses, yet systematic investigation into their causative factors had been limited until this research. Parkin and colleagues conducted a case-control study examining racehorses that sustained fatal lateral condylar fractures against matched controls, analysing veterinary, racing, and environmental data to identify statistically significant risk factors. The study identified multiple modifiable and non-modifiable risk factors—including racecourse surface characteristics, horse age and sex, training history, and pre-existing bone remodelling—that substantially increased fracture likelihood. Understanding these specific risk factors provides racing authorities, trainers, veterinarians and farriers with evidence-based targets for intervention, from track maintenance protocols and load management strategies to enhanced pre-race screening for subclinical bone pathology. Implementation of risk-reduction strategies informed by this data could meaningfully decrease preventable fatalities on UK racecourses, making this foundational work essential reading for anyone involved in racehorse welfare and management.

Practical Takeaways
- •Understanding risk factors for lateral condylar fractures should inform pre-race assessment and conditioning protocols for racing horses
- •Implementation of evidence-based intervention strategies targeting identified risk factors could significantly improve racecourse safety outcomes
- •Track surfaces, training intensity, and bone quality monitoring may be critical areas for injury prevention programs
Key Findings
- •Lateral condylar fractures of the third metacarpus/metatarsus are the leading cause of equine fatality on UK racecourses
- •Identification of risk factors for these injuries can inform intervention strategies to reduce racecourse fatalities
