The reliability of the Greulich–Pyle method in bone age determination among Australian children

Bone age (BA) determination in skeletally immature children has been used as a measurement of growth for many years. The Greulich–Pyle (G&P) method of estimating BA is most commonly used. The standards used within this atlas were compiled from research conducted on normal white children in the United States, during the 1930s. The applicability of G&P beyond populations similar to its own can be variable. The aim of this study was to determine the accuracy of G&P in BA determination among Australian children.
