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.
数字性骨关节炎主要涉及远端指间关节（DIP）和第一腕掌关节（CMC-I）。赫伯登结节常伴随DIP关节的骨关节炎。近端指间关节（PIP）的骨关节炎可能更疼痛且炎症更明显。它可能是布夏尔结节的起因。DIP和PIP关节可能是糜烂性病变的部位。掌指关节（MCP）的骨关节炎很少见。CMC-I关节的骨关节炎有时会导致拇指畸形，影响其功能，并导致大鱼际肌萎缩。治疗包括非药物和药物治疗方法。保守治疗失败后建议进行手术。
