[Caudal regression syndrome and diastematomyelia. What is contained in Hohl's first publication of sacral dysgenesis? (author's transl)].

Hypoplasias and defective development of the caudal end of the spine are called caudal regression-syndrome. Occasionally such patients also show diastematomyelia. This combination, clinically important and of developmental interest is described on the basis of the first description and an observation of the author. The means of diagnosis are discussed.
