Bone dysplasia.

Bone dysplasia is a large group that encompasses 436 rare diseases. Many of them are characterized by short stature or decreased growth velocity during puberty. The diagnosis of short stature due to skeletal dysplasia relies on (i) physical features such as disproportionate trunk/limbs, short limbs or extremities and/or stocky build, (ii) radiographic features to analyze mineralization, maturation and bone morphology, and (iii) whenever possible, the genetic characterization. Bone dysplasia mostly affect many organs, and therefore require multidisciplinary follow-up and care. The role of the pediatric endocrinologist is to assess the growth potential of these patients in coordination with the other caregivers, offer the best management of the growth to limit the psychosocial consequences of the extreme short stature and bone deformities.
