[Sacrococcygeal malformations: a report on 67 cases (author's transl)]

A series of 67 personal observations of sacrococcygeal malformation are reported, and these are reviewed together with the 249 cases in the published literature. The clinical picture and pathogenic mechanisms are discussed, and the frequent association of other congenital abnormalities, more particularly of the ano-rectal type, is stressed. The functional results obtained depend on the severity of the neurological lesions, associated malformations, and the quality of the treatments used.
