Since the first description of unusual type of osteoarthritis involving interphalangeal joint with acute inflammatory change by Carin in 1961, many of the subsequent cases were reported as the term "inflammatory osteoarthritis" referring to the inflammatory process such as painful nodule, pustule and erythema, or as the term "erosive osteoarthritis" referring to the erosion in and around the joint seen on the radiological films. Although the exact pathogenesis of the disease is not yet known, it is generally thought to occur from either the destruction or atrophy of the subchondral bone by external pressure rather than the inflammatory change of the synovium. Herein we report a case of inflammatory osteoarthritis seen in a 53 yr-old woman which developed following the excessive physiotherapy of finger joints in the course of treatment of ankylosis developed during the treatment of metacarpal fractures with brief review of literatures.
