Osteochondrosis Dissecans (OCD)

Many of the dog breeds that are of the large rapidly growing variety, are affected by Osteochondrosis Dissecans. The age of onset is usually between 4 and 12 months of age. This condition most often occurs in the shoulders or elbows, but can affect other joints. Cartilage covers the head of the long bones, forming a joint, the cartilage serves as a cushion, which is subject to stress and prone to damage. Cracks can form in the cartilage, the cartilage itself can tear - forming flaps, or sections of the cartilage can tear away from the bone - free floating in or near the joint. The damaged cartilage leads to inflammation of the joint (arthritis), pain and lameness. OCD is thought to be a combination of genetic and environmental factors. Genetic factors may be direct (polygenetic), or indirect(improper conformation of the parent(s) passed on to the offspring).Environmental factors can range from poor diet to trauma induced. Small cracks in the cartilage can occasionally be healed through strict confinement. Other cases usually require surgical correction.
