Osteochondrosis Dissecans (OCD)

is a disease of the cartilage of the joints primarily in maturing large and giant breed dogs.  Failure of proper bone formation from cartilage leads to cartilage thickening and can lead to fissures in the cartilage, cartilage flaps and/or a free flap or "joint mouse."   Typical symptoms are pain and lameness.  OCD is most common in the shoulder.  Male dogs are more frequently affected than female dogs.  Diagnosis is by a physical examination by your veterinarian and X-rays.  Surgical treatment to remove the flap or joint mice is most frequently recommended.
