Osteochondritis Dissecans in Horses

Share This

Osteochondritis dissecans (OCD) of the carpal joints is uncommon. The typical presentation is a yearling with synovial effusion. Lameness is usually present and can be exacerbated by carpal flexion. Radiographs show the presence of subchondral lucencies typical of OCD, most commonly in the distal radius. Treatment is arthroscopic surgery, but refragmentation and development of osteoarthritis has been seen. The prognosis is fair to guarded. (Also see Lameness in Horses: Osteochondrosis in Horses.)
