“…[5,9,16,[26][27][28] In another study conducted in Turkey around Sivas province, which also has a high altitude and cold climate, partial retardation was detected in comparison to Malatya which has a lower altitude. [29] Therefore, climate, nutrition and socio-economic factors are thought to play an important role on the growth rate of children. It is also pointed out that warm climate and hot environment cause premature maturation.…”

Objectives: Bone age (BA) is used in age determination for a number of medico-legal reasons. One of the most commonly used radiographic methods in BA assessment is to compare hand-wrist radiographs with a standard reference. In this study, Greulich-Pyle (GP) method was used to determine the bone maturation values of a population of children and adolescents living in the city of Erzurum, Turkey. Methods: Hand and wrist radiographs of 507 individuals (243 boys and 264 girls) aged between 7-19 years were evaluated and the BA was estimated by a radiologist using the GP method. Difference between estimated BA and chronological age (CA) was analyzed. Results: In boys, except for the ages of 12,13 and 17 years, BA was significantly lower than the chronological age. In girls, BA was significantly lower than CA at 7, 8, 18 and 19 years of age, but not statistically different in the other ages. Conclusion: According to the GP atlas, it is suggested that many factors including high altitude, cold climate, environment, nutrition, genetics, ethnics and socioeconomic diversities might cause differences between BA and CA. Our results obtained in this study suggest that this method can guide the determination of bone age in children living in Erzurum, Turkey. However, in certain age groups for both genders, the GP method significantly underestimated skeletal age.

Objective To determine whether the Greulich and Pyle (G&P) atlas is applicable when applied to populations of different ethnicity. Methods A systematic review of studies published between 1959 and 15th February 2017 identified from the Embase, MEDLINE and Cochrane databases was undertaken. Quality of the studies was assessed using the National Institute for Health and Care Excellence tool. Meta-analysis used mean differences and standard deviations as summary statistics for the difference between bone age (BA) and chronological age (CA). Results A total of 49 studies were included of which 27 (55%) were related to Caucasian populations. Of the 49 eligible studies, 35 were appropriate for further meta-analysis. In African females, meta-analysis showed a significant mean difference between BA and CA of 0.37 years (95% CI 0.04, 0.69). In Asian males, meta-analysis showed significant differences between BA and CA of -1.08, -1.35, -1.07, -0.80 and 0.50 years for chronological ages of 6, 7, 8, 9 and 17 years, respectively. Meta-analysis showed no significant differences between BA and CA in African males, Asian females, Caucasians and Hispanics. Conclusions The G&P standard is imprecise and should be used with caution when applied to Asian male and African female populations, particularly when aiming to determine chronological age for forensic/legal purposes. Key Points • In African females, bone age is significantly advanced when compared to the G&P standard. • In Asian males, bone age is significantly delayed between 6 and 9 years old inclusive and significantly advanced at 17 years old when compared to the G&P standard. • The G&P atlas should be used with caution when applied to Asian and African populations, particularly when aiming to determine chronological age for forensic/legal purposes.
