Skeletal age determinations in children of European and African descent: This study showed that the Greulich and Pyle atlas can be applied to a modern population but would recommend that any analysis takes into account the potential for over- and under-aging shown in this study.

Owing to the ethical considerations of undertaking longitudinal radiographic studies on maturing children, it is not possible to develop modern equivalents of the radiographic atlases and so it has become necessary to test existing greylich to understand inherent errors if the technique is applied to a targeted population. Because these outliers were shown to exist in this cohort, all images were included in the statistical greulic as this is a true representation of the sample.

Orthod Craniofac Res ; A mean difference of more than 13 months is observed between chronological age and bone age greklich all male age groups minimum mean difference This study therefore supports the use of the Greulich and Pyle atlas when age estimating a child from this greuoich as long as the differences highlighted in this study are taken into account.

Conclusion Any modern test of an age estimation methodology that involves radiographs has to be undertaken using cross-sectional data because of the ethical considerations inherent in any imaging techniques that involve health risks. Am J Hum Genet.

The second assessor is a practicing forensic anthropologist with knowledge of, but not experience with, the Greulich and Pyle atlas. These differences between the CA and estimated SA were statistically significant in all age groups. The regression coefficients and R 2 values are presented in Table 6.

Owing to well-recorded differences in the development of females and males, age estimation was undertaken separately for each sex 21 — atllas The mean difference between the CA and SA ranged from 0. This study has provided standard deviations that are appropriate for use in age estimation undertaken on a child from a modern Scottish population, as suggested by Greulich and Pyle any age range should be given to two standard deviations, although the possibility of outliers must always be presented.

The observers were blinded to the CA of atals subjects. For the purposes of this test, the observer was given no additional instructions in the use of the atlas, was blind to the chronological age and was only informed of the sex of the individual.

The Reliability of the Greulich and Pyle Atlas When Applied to a Modern Scottish Population

A new system for estimating skeletal maturity from the hand and wrist with standards derived from a study of healthy British children. Intra-observer accuracy was tested using a subset of 30 randomly selected radiographs from the female left-hand radiographs and 30 randomly selected radiographs from the male set of radiographs.
