Bone age corresponds to chronological age in: March 2009
Ans. B: Familial sho stature The causes of sho stature can be divided into 3 broad categories: chronic disease (including undernutrition genetic disorders), familial sho stature, and constitutional delay of growth and development. Delayed bone age in a child with sho stature is suggestive of hormonal/systemic disorder. Normal bone age in a sho patient is more likely to be caused by a genetic cailage dysplasia or growth plate disorder. The hallmarks of familial sho stature (also referred to as genetic sho stature) include bone age appropriate for chronologic age, normal growth velocity, and predicted adult height appropriate to the familial pattern (using the BayleyPinneau or Tanner-Goldstein-Whitehouse tables). By contrast, constitutional growth delay is characterized by delayed bone age, normal growth velocity, and predicted adult height appropriate to the familial pattern
