The abnormal vertebra acts as a wedge in the spine, resulting in curvature away from where it is present.Block vertebra: lack of proper segmentation leading to fusion of adjacent vertebral bodies.Craniosynostosis: premature fusion of cranial sutures.Skeletal dysplasias: group of complex and heterogeneous disorders that affect bone development and growth, resulting in alterations of bone size, shape, density and/or integrity.
