More than 372 different genetic disorders of the skeleton have been described by the International Skeletal Dysplasia Society as constitutional diseases of bone1; collectively, dysplasias represent most of the intrinsic disorders of bone with the dysostoses comprising the rest. The overall frequency of the skeletal dysplasias is about 1 in 4000 births,2 making this class of disorders about as common as neurofibromatosis type 1 or Turner syndrome, conditions much better known to the pediatric practitioner.
