title: Short stature in an adolescent due to spondyloepiphysial dysplasia tarda.
abstract: A 15-year-old boy had normal growth until age 7 years and decreased growth velocity thereafter. His upper segment/lower segment (U/L) ratio was 0.8. Anterior pituitary function was normal. Roentgenograms revealed characteristic findings of spondyloepiphysial dysplasia tarda (SDT). The sitting height measurement or U/L segment ratio is important in identifying this condition. This condition should be considered in the differential diagnosis of short stature in males.
