[Congenital tilt of the sacral plateau and the fate of the spine].

Congenital deformities of the sacrum are relatively rarely described syndromes. In this report, 16 cases of sacral deformity with resultant obliquity of the sacral plateau are described. With respect to morphological criteria 5 different types can be distinguished. Development of static scoliosis results from congenital deformity of the sacral plateau. Longterm results of up to 17 years in 8 of the 16 cases are presented. Operative and conservative treatment possibilities are discussed.
