TW2 and TW3 bone ages: time to change?

Abstract
To explore the changes that have occurred between these two publications, we retrospectively compared TW2 RUS (radius, ulna and short bones) and TW3 RUS bone age assessments in 142 children in two diagnostic groups (idiopathic short stature or constitutional delay in growth and puberty and congenital adrenal hyperplasia) with a range of bone ages from delayed to advanced.
