Osteochondritis Information

Osteochondritis is a painful type of osteochondrosis where the cartilage or bone in a joint is inflamed.[1]

It often refers to osteochondritis dissecans (sometimes spelled dessecans, and abbreviated OCD). The term dissecans refers to the "creation of a flap of cartilage that further dissects away from its underlying subchondral attachments (dissecans)".[2]

The other recognized types of osteochondritis are osteochondritis deformans juvenilis (osteochondritis of the capitular head of the epiphysis of the femur)[1] and osteochondritis deformans juvenilis dorsi (osteochondrosis of the spinal vertebrae, also known as Scheuermann's disease).[1][3]

Osteochondritis, and especially osteochondritis dissecans, can manifest in animals as a primary cause of elbow dysplasia, a chronic condition in some species and breeds.[4]
