[Dysspondylis: a contribution to Scheuermann's disease].

Juvenile aberrations of the vertebral bodies and intervertebral discs are abnormalities of the chondral, periosteal and apophyseal ossification. Differentiation of clinically insignificant variations and potentially or manifestly pathogenic dysspondylies is suggested. The occurrence of abnormalities of bodies and discs is different in particular parts of the spine. The semiology of eight dysspondylies in individual segments of the spine is described. M. Scheuermann presents the most frequent dysspondyly.
