The cause of osteochondritis dissecans is unknown. The reduced blood flow to the end of the affected bone might result from repetitive trauma — small, multiple episodes of minor, unrecognized injury that damage the bone. There might be a genetic component, making some people more inclined to develop the disorder.

What happens if osteochondritis dissecans is left untreated?

If left untreated, osteochondritis dissecans can damage the cartilage in the joint, and loose pieces of bone and cartilage may even break off into the joint. In the long term, untreated osteochondritis dissecans can also lead to arthritis. Osteochondritis dissecans most commonly affects the knee, ankle and elbow.

Can osteochondritis heal itself?

Healing of the osteochondritis dissecans lesion should be monitored by routine follow-up imaging tests. In many younger children who still have a lot of growing to do, the lesion often heals on its own. Surgical intervention may be needed if nonsurgical treatment is not effective.

Can osteochondral defect heal on its own?

In general, osteochondral lesions do not heal on their own. Treatment is usually determined by the stability of the lesion and the amount of pain that it causes you.

Is OCD in horses genetic?

Horses of any breed, size, and shape are at risk of osteochondritis dissecans (OCD), a developmental orthopedic disease, if predisposing factors are present. For years, researchers have believed that genetics play a role in the development of OCD, and science supports this assertion.

Do horses remember you after years?

Horses also understand words better than expected, according to the research, and possess “excellent memories,” allowing horses to not only recall their human friends after periods of separation, but also to remember complex, problem-solving strategies for ten years or more.

• stage II. stable on probing. partial discontinuity of the lesion from the host bone.
• stage III. unstable on probing. fragment not dislocated.
• stage IV. dislocated fragment.
