Greulich and Pyle method

Last revised by Daniel J Bell on 3 Jul 2020

The Greulich and Pyle method is one of the two main ways to assess the bone age of children. 

Both main methods of bone age assessment require a left hand and wrist radiograph. The Greulich and Pyle method makes use of a standard bone age atlas that the reporter can compare their image to and make an estimation of bone age.

This is different to the Tanner-Whitehouse method which assesses and scores each bone before calculating an estimated age based on the assessed bones.
