[Metatropic dysplasia. A rare skeletal anomaly (author's transl)].

Metatropic dwarfism is a rare form of bone dysplasia which is manifest already at birth. One feature is an early manifestation of progressive kyphoscoliosis, causing a reversal of body proportions. The radiological changes permit classification by establishing the presence of anisospondylia, a "halberd shaped" pelvis and epimetaphyseal ossification disorders.
