Horse Hip Dysplasia and Sacroiliac Disease: Welfare

Sacroiliac joint disease causes chronic back pain in performance horses. Recognition, diagnosis, and appropriate management improve welfare for affected horses.

Key Facts

Sacroiliac joint disease is an increasingly recognized cause of poor performance and back pain in horses
Signs include poor hindlimb engagement, difficulty collecting, asymmetrical hindquarters, and reluctance to canter
Diagnosis requires nuclear scintigraphy, radiography, or ultrasound — routine physical examination often underdiagnoses this condition
Sacroiliac corticosteroid injections under ultrasound guidance provide significant relief in many horses
Physiotherapy, muscle building exercises, and modified work programs support recovery and management
Horses with sacroiliac pain may be labeled as reluctant or difficult before diagnosis identifies the physical cause

Welfare Considerations

Sacroiliac disease creates welfare problems on two levels: the pain itself, and the misattribution of pain-related behavior to temperament or training problems. Horses that are reluctant to collect, resist lateral movements, or become tense in work may be experiencing pain rather than exhibiting behavioral problems. Applying increased training pressure to a horse with undiagnosed sacroiliac pain causes suffering while failing to address the actual problem. Welfare-conscious horsemanship always investigates pain causes before assuming behavioral explanations.

What You Can Do

Investigate any horse showing asymmetric hindquarters, poor hindlimb engagement, or resistance in collected work
Request imaging (scintigraphy or ultrasound) if sacroiliac disease is suspected — physical examination alone is insufficient
Pursue veterinary treatment including corticosteroid injections if sacroiliac disease is confirmed
Work with a qualified physiotherapist on appropriate exercise programs during rehabilitation
Adjust work expectations during treatment and recovery — avoid demanding collected work until pain is controlled
Learn the signs of sacroiliac pain to distinguish it from behavioral problems
