This atlas is intended to give obstetricians, paediatricians, neonatologists, radiologists, molecular and clinical geneticists, as well as anatomo-pathologists, a thorough insight into conditions (and variants) of skeletal dysplasias. Clinical and imaging findings are properly illustrated, enriched by updated genetic information. This acclaimed text returns in a revised form, with updated material particularly on the new knowledge surrounding the genetic basis and mechanism for the various skeletal dysplasias. No clinician dealing with fetal or neonatal skeletal diagnosis or treatment will want to be without access to the wealth of illustrations and detail condensed here.
