JCEM has published an article on our new method for adult height prediction based on BoneXpert bone age: full paper
The new method is available as a calculator at this site and it is also built into the BoneXpert bone age computer program.
The new method was estimated on the basis healthy children from the First Zurich Longitudinal Study, originally conducted by Prader et al., and subsequently validated on the Third Zurich Longitudinal Study of modern Swiss children. The establishment of this method is an important achievement: The information processing from the hand X-ray to the predicted adult height height can now be done in a standardised, reproducible manner without any human rater variability.
The method is intended for normal children and untreated children with idiopathic short stature, tall stature, precocious puberty and constitutional delay of growth and puberty.
