Obsolete eponym used to indicate a combination of Klippel-Feil syndrome (congenital brevicollis) and Bonnevie-Ullrich syndrome (pterygium colli). Characteristics are short stature, blepharoptosis, cleft palate, abnormal fusion of the vertebrae, pterygium colli, and camptodactyly. Transmitted as an X-linked dominant trait.

The first description was made by Herman Nielsen in 1934. E. Moldenhauer [dermatologist, Rostock], in 1964 described 3 affected women in 3 generations. Probably autosomal dominant inheritance with variable expressivity.
