Recurrent palmar dislocation of the distal radioulnar joint is not a common injury. We report one case in a 73-year-old female. This injury was incorrectly diagnosed at the first presentation because there has been no distinct deformity at the wrist and extension-flexion was normal. The need for proper physical examination and accurate radiographic positioning is stressed. Distal diaphysis resection combined with distal radioulnar arthrodesis (modified Sauve-Kapandji procedure) was the preferred method of treatment in an old patient. Two years after the injury, the patient was asymptomatic.
