title: [Clinical presentation imaging and treatment of digital osteoarthritis].
abstract: Digital osteoarthritis relates to primarily the distal interphalangeal (DIP) and first carpometacarpal (CMC-I) joints. Heberden's nodes often accompany osteoarthritis of the DIP joints. Osteoarthritis of the PIP joints can be more painful and more inflammatory. It can be at the origin of Bouchard's nodes. The DIP and the PIP joints can be the seat of erosive lesions. Osteoarthritis of the MCP joints is rare. Osteoarthritis of the CMC-I joint is sometimes at the origin of a deformity of the thumb impairing its function and an atrophy of the thenar muscles. Treatment includes non-pharmacological and pharmacological modalities. Surgery is proposed after failure of the conservative approach.
