Opsismodysplasia (opsismos in Greek = late) is a rare chondrodysplasia, first described in 1977 by Zonana et al1 as a unique chondrodysplasia and designated "opsismodysplasia" only in 1984.2 The disorder is characterised clinically by micromelia with extremely short hands and feet and respiratory distress responsible for death in the first few years of life.2 The main radiological features include severe platyspondyly, major delay in skeletal ossification, and metaphyseal cupping. To date, 13 cases have been reported and recurrence in sibs and/or consanguinity have suggested an autosomal recessive mode of inheritance.1–6 Here, we describe the clinical, radiological and chondro-osseous findings of 12 previously unreported cases in nine families. We show that opsismodysplasia is not a consistently lethal condition and we identify the severity of the delayed bone ossification as an important feature, distinct from other forms of spondylo(epi)metaphyseal dysplasias.
