The Bayley-Pinneau method for adult height prediction (AHP) from age, bone age and height was developed in 1952 based on American white children. In 2009, the method was modernised through the BoneXpert AHP based on automated bone age, better math and more recent Caucasian longitudinal studies.
We are proud to present now an extension of the method to cover three major ethnicities in the world: Caucasians, Asians and Africans.
This was possible through access to a longitudinal study of African children in Johannesburg, and a longitudinal study of Asian children in Japan.
The AHP is now based on version 3 of BoneXpert bone age, and for Caucasians it has been extended down to bone age 2 years.
For Caucasians, the difference between version 3 and the old AHP version is less than 1 cm in four out of five cases.
BoneXpert for automated bone age assessment is installed in more than 150 hospital clinics and the system has performed more than 500.000 bone age measurements in clinical use. BoneXpert is validated in more than 20 peer-reviewed publications and has become the standard application for bone age measurements.
