Osteochondrosis in horses: what real veterinary cases show
Osteochondrosis in horses is a developmental joint disease that affects the cartilage and underlying bone in young, growing horses. It occurs when the normal process of bone formation from cartilage is disrupted, leading to cartilage defects and joint instability. This condition is relatively common in young horses, particularly those bred for performance.
Owners typically notice lameness or swelling in the affected joints, which can vary in severity. Early detection is crucial as it can prevent further joint damage and improve the horse's long-term prognosis. Recognizing the signs early allows for timely intervention and management.
What vets typically check for
- Perform a thorough physical examination and assess for lameness.
- Take radiographs (X-rays) of the affected joints to identify lesions.
- Consider advanced imaging like MRI or CT for detailed evaluation.
- Evaluate the horse's diet and growth rate as contributing factors.
- Discuss surgical or medical treatment options based on severity.

- Ocular tuberculosis in a horse.
The Veterinary record
This case report describes a horse that developed a serious form of tuberculosis affecting its eyes. Over time, the horse lost weight and became increasingly blind in both eyes. Unfortunately, the horse was eventually put to sleep due to the severity of its condition. Tests revealed that the horse had widespread infection from a type of bacteria called Mycobacterium avium, whic
- Evidence of occipitoatlantoaxial malformations independent of the HOXD3 mutation in an Arabian horse.
Journal of equine veterinary science · 2026
A 3-year-old Arabian gelding was brought in with severe neck stiffness and difficulty coordinating his movements, known as proprioceptive ataxia. X-rays showed serious malformations in the bones of his neck, but testing for a known genetic mutation linked to this condition came back negative. Unfortunately, due to his poor prognosis and significant mobility issues, the decision
- Racing and sales performance in Thoroughbred yearlings after carpal osteochondral fragment removal.
Equine veterinary journal · 2026
A group of 46 Thoroughbred yearlings with carpal osteochondral fragments (COF) were studied to see how these fragments affected their sales prices and racing performance. The yearlings were either treated with surgery to remove the fragments or managed without surgery. The results showed that yearlings with COF had lower sales prices and fewer racing opportunities compared to h
- Imaging Findings of Congenital Distal Interphalangeal Joint Dysplasia in a 3-Month-Old Friesian Foal.
Veterinary radiology & ultrasound : the official journal of the American College of Veterinary Radiology and the International Veterinary Radiology Association · 2025 · Netherlands
A 3-month-old Friesian colt was brought in because he was limping badly on both front legs, and the lameness was getting worse. X-rays and a full-body CT scan showed serious bone changes in the joints of his legs, particularly around the navicular bone and the ends of the bones in his toes, while the rest of the joint looked normal. Other joints also had small areas of bone dam
- Fibrocartilaginous Emboli in a 15-Year-Old Pony Mare.
Veterinary medicine and science · 2025 · United States
A 15-year-old pony mare was diagnosed with a condition called fibrocartilaginous embolic myelopathy (FCE), which affects the spinal cord. She experienced focal seizures and was unable to stand for about 12 hours before being euthanized. A detailed examination of her spinal cord showed severe damage and the presence of material that indicated a cartilaginous substance, which is
- Bilateral congenital cystic eye with intraocular tissue differentiation in a horse.
The Journal of veterinary medical science · 2025 · Japan
This case involves a 1-day-old horse that was found to have a rare eye condition called congenital cystic eye (CCE), which is a problem that happens during development and leads to cysts in the eye area. In this horse, the cysts were not just simple fluid-filled sacs; they actually contained some eye structures like the lens and optic nerve, which is unusual for this condition.
Frequently asked questions
- What causes OCD in horses?
- OCD is caused by a disruption in the normal development of cartilage into bone, often influenced by genetics, nutrition, and growth rate.
- Can OCD be cured?
- While OCD cannot be 'cured,' it can be managed effectively with surgical intervention and appropriate care to improve joint function and reduce pain.
- Is OCD preventable?
- While not entirely preventable, risk can be reduced by managing diet, ensuring balanced nutrition, and avoiding rapid growth in young horses.
