Congenital trigger thumb is a trigger thumb in infants and young children. Triggering, clicking or snapping is observed by flexion or extension of the interphalangeal joint (IPJ). In the furthest stage, no extension is possible and there is a fixed flexion deformity of the thumb in the IPJ. Cause, natural history, prognosis and recommended treatment are controversial.
