We herein present a case of radial wrist pain following trauma. Magnetic resonance imaging showed a large area of abnormal soft tissue in the scapho-trapezial joint. The patient was treated successfully by complete resection of the soft tissue. The soft tissue was diagnosed to be synovial fringe based on a histological study. Synovial fringe is frequently reported as a cause of knee and elbow pain, however, it is a rare cause of wrist pain at the scapho-trapezial joint.
