[Syndrome of symphalangism and stapes fixation: an autosomal dominant hereditary disease (author's transl)].

The autosomal dominant hereditary syndrome of symphalangism and stapes fixation consists of multiple synostoses, most frequently symphalangism, in addition to synostoses of carpal and tarsal bones and radio-ulnar synostoses, various other malformations of the limbs (restricted joint movement or syndactylism) and variable degrees of conduction disorders due to stapes fixation, starting in childhood. A family tree of four successive generations with various forms of the syndrome is described.
