title: Triphalangism and pseudotriphalangism of the thumb in children.
abstract: In 10 children with altogether 17 malformed thumbs radiography revealed true triphalangism in 13 of the thumbs and pseudotriphalangism in the remaining 4. Two varieties of triphalangism were distinguished, and clinically significant morphologic variation was recognized also in pseudotriphalangism.
