title: Carpal involvement in inflammatory (erosive) osteoarthritis.
abstract: Inflammatory or erosive osteoarthritis, in addition to the classical digital distribution, may involve the carpus. Characteristic carpal changes are restricted to the radial aspect of the wrist and consist of narrowing, eburnation, osteophytosis, and mild subluxation of the first carpometacarpal and trapezio-scaphoid joints. Radiographic findings and differential diagnosis are discussed.
