Skeletal dysplasias are a heterogenous group of dysplasias that include more than 200 recognized conditions. They are disorders of growth and remodeling of bone and cartilage. Most disorders result in short stature, which is defined as height more than 2 standard deviations below the mean for the population at a given age. Lamy and Maroteaux first delineated this syndrome in 1960 and coined the term diastrophic dwarfism. The term diastrophic is derived from a Greek root meaning distorted; it is a geological term used to describe the bending and twisting of the earth's crust during geomorphogenesis. This terminology seems appropriate for this disorder, in which the skeleton appears to be twisted. In 1977, at the Second International Conference for Nomenclature for Constitutional Diseases of Bone, the name was changed from diastrophic dwarfism to diastrophic dysplasia.
