Characteristic imaging findings of osteoarthritis?
Osteophyte formation, subchondral sclerosis, and joint space narrowing are the characteristic features of OA, also known as degenerative joint disease (DJD).
OA most commonly affects the distal interphalangeal (DIP) and proximal interphalangeal (PIP) joints of the hands and the major weight-bearing (hip and knee) joints.
In addition, the carpal joints at the base of the thumb are commonly affected. Any joint that is damaged by trauma resulting in an irregular articular surface can prematurely be affected by OA as well.
