[Jacob-list] Jacob-list Digest, Vol 42, Issue 50

This OCD is not the same you find in horses. It only refers to Jacobs and it stands for Occipital Condylor Displaisure.

What does OCD stand for?

Osteochondritis Dissecans: Osteochondritis Dissecans
A disease process by which subchondral bone (bone just below the
articular cartilage of a joint) loses its blood supply. The bone and
its overlying cartilage become damaged, and a fragment of bone may
separate from contiguous bone to form loose bodies in the joint; the
articular cartilage may or may not remain intact. The process occurs
particularly in the femoral condyles of the knee, and also in the
ankle and hip joints. The condition may be due to inherited anatomical
abnormalities, obstruction of the blood supply to subchondral bone, or
physical trauma to the joint.
