Which radiographic feature is not typical of osteoarthritis?

Explanation:
Periarticular osteopenia is not typical of osteoarthritis. Osteoarthritis is a degenerative, noninflammatory process, and its radiographic signs reflect cartilage loss and bone remodeling: asymmetric joint space narrowing, osteophyte formation at the joint margins, and subchondral sclerosis (and sometimes subchondral cysts). Periarticular osteopenia, or reduced bone density around the joint, is more commonly seen with inflammatory arthritis or disuse/osteoporosis and points away from pure OA. So the feature that does not fit OA patterns is the periarticular osteopenia.
