[Klippel-Feil syndrome and status dysraphicus].
Apart from the obligatory symptoms of Klippel-Feil syndrome (short neck, low hairline on nape, limited rotation of the head) many other so-called facultative dysraphic impairments may be found. The most common is spina bifida, which is the prototype of the "dysraphia syndrome". Therefore, Klippel-Feil syndrome belongs to a heredo-degenerative constitution type of "status dysraphicus".
