Increased Bone Density,The terms ‘osteopetrosis’ or ‘Albers-Sch?nberg disease’ have been used loosely for a large number of conditions in which generalised increased radiological density of the skeleton is present. These designations are more accurately reserved for the specific dominant and recessive conditions which form the subject of this section.

Craniotubular Dysplasias and Hyperostoses,The craniotubular dysplasias and hyperostoses are a group of disorders in which abnormal skeletal modelling and increased bone density are the principal features.

Vertebral Anomalies,Abnormalities of vertebral development such as odontoid hypoplasia, hemivertebrae and failure of segmentation are components of a number of bone dysplasias. Of these, the Klippel-Feil syndrome and the spondylocostal dysostoses have vertebral anomalies as a principal feature.

Limb and Digital Anomalies,It has been shown in large surveys (Henkel and Willert 1969; Rogala et al. 1974) that congenital absence of a limb or segment of a limb is usually non-genetic, and a detailed review of these anomalies is therefore outside the scope of this book. A concise summary of the present knowledge of these disorders has been given by Lenz (1980).
