Summary
# Editorial Summary Between 1997 and 2000, researchers analysed veterinary insurance claims for over 100,000 Swedish horses to establish comprehensive morbidity rates across different ages, sexes, breeds and geographic regions. Locomotor conditions dominated the disease landscape, with joints being the most frequently affected body system; fetlock arthritis alone accounted for the highest single diagnosis, followed by undefined lameness, other locomotor disorders, skin trauma, polyarticular arthritis and colic. Geldings displayed notably higher disease rates in joint, whole-body, skeletal and respiratory conditions compared to mares and stallions, though sex differences were minimal across the remaining four major organ systems. These findings provide practising equine professionals with evidence-based baseline prevalence data for the conditions encountered most frequently in clinical practice, helping to inform diagnostic prioritisation, owner communication about risk and research direction. The dominance of locomotor pathology—particularly at the fetlock joint—underscores why farriers, physiotherapists and veterinarians must prioritise early recognition and intervention in forelimb lameness, whilst the higher rates of systemic disease in geldings may reflect sex-related factors in management, temperament or use that warrant further investigation.

Practical Takeaways
- •Fetlock arthritis and undefined lameness dominate equine disease presentation; focus diagnostic and preventive efforts on joint health and specific fetlock assessment.
- •Geldings show higher disease susceptibility in joint and skeletal systems—consider sex-specific management and monitoring protocols.
- •Locomotor conditions account for a large proportion of insurable morbidity; early intervention in joint disease may reduce insurance claims and improve horse welfare.
Key Findings
- •Joints were the most commonly affected body system, followed by unspecified/whole body conditions, skin, and digestive system.
- •Fetlock arthritis was the most common specific diagnosis, followed by lameness of undefined origin and other locomotor problems.
- •Geldings had significantly higher rates of disease in joints, unspecified/whole body, skeletal, and respiratory systems compared to other sexes.
- •Disease incidence varied by age, sex, breed group, geographic region, and human population density across over 100,000 insured horses.
