Osteophyte excision is a mainstay of treatment for mucous cyst combined with Heberden's node in a distal interphalangeal joint or in an interphalangeal joint of the thumb. The aim of this study was to evaluate the results of osteophyte excision without cyst excision for the treatment of a mucous cyst combined with Heberden's node. The medical records of 37 patients (42 cases) with a mucous cyst with Heberden's node were retrospectively reviewed. Thirty-eight of 40 cases with available pre-operative simple radiographs showed evidence of joint arthrosis. A T-shaped skin incision of the joint capsule between the extensor tendon and lateral collateral ligament was used. Osteophyte excision without cyst excision was performed. All cysts, except one, regressed without recurrence or a skin complication after osteophyte excision, but eight cases showed post-operative pain and loss of range of motion. Osteophyte excision without cyst excision may be a good treatment choice for mucous cyst of the finger.
