SUMMARY METATROPIC DYSPLASIA is a spondylo‐epi‐metaphyseal dysplasia with characteristic clinical and radiographic features. 37 cases of the disorder were reported up to 1983 accordingly to Beck et al. 14 cases of spondylo‐epi‐metaphyseal dysplasia of metatropic variety from 9 paediatrk institutions have been analysed. Radiologically and clinically we discern four groups of patients with features of metatropic dysplasia. 1. A lethal, pen‐natal type, 2. An autosomal recessive type with diagnostic radiographic findings and often fatal outcome in the first few years of life, 3. A rare dominant type, 4. A mild type consistent probably of different spondylo‐epi‐metaphyseal dysplasias which show mild metatropic changes. (Metatropic Dysplasia Variants).
