Definition


Marginal osteophytosis is the presence of one or more osteophytes on the outer side of a joint. They almost only manifest themselves in the course of osteoarthritis, a degenerative disease of joint cartilage. A marginal osteophytosis is a bony projection that develops solely on the exterior side of the joint, not on the interior. In cases of coxarthrosis, which is osteoarthritis of the hip, marginal osteophytosis is common, and manifests either on the exterior sides of the acetabulum, the area of the pelvis where the head of the femur is inserted, or below the head of the femur, where it joins with the femoral neck.
