The Greulich-Pyle (GP) Atlas of skeletal maturation has been prepared in white children who born between 1917 and 1942 in the USA, and is frequently used for assessment of skeletal maturity. In this study, we investigated whether or not the GP method is sufficient for Turkish children for the determination of the skeletal age.
Plain radiographies of left hands and wrists of 225 healthy boys between 7 and 17 years of age were taken. Pubic hair (PH) stages of boys were determined by using the Tanner criteria. Mean chronological ages and mean skeletal ages according to GP Atlas were compared for each age groups and each PH stage.
Mean skeletal ages were delayed 0.61, 0.72, 0.54, 0.39, 0.25, 0.39, and 0.32 years than the mean chronological ages in the 7-13 years age groups, respectively, and advanced 0.13, 0.01, 0.89, and 0.52 years in the 14-17 years age groups. In PH stages 1, 2, and 3, mean skeletal ages were delayed 0.67, 0.51 and 0.40 years than the mean chronological ages, respectively. In PH stages 4 and 5, mean skeletal ages were advanced 0.66 and 0.76 years than mean chronological ages.
The results suggest that Turkish boys may have a different tempo of skeletal maturation during pubertal development from that of American children which GP standards were derived. Therefore, GP Atlas is not completely applicable to Turkish boys but can be used with some modification.
格吕利希-派尔（GP）骨骼成熟度图谱是根据1917年至1942年间在美国出生的白人儿童编制的，常用于评估骨骼成熟度。在本研究中，我们调查了GP方法对于土耳其儿童确定骨骼年龄是否足够。
对225名7至17岁健康男孩的左手和手腕进行了X线平片检查。使用坦纳标准确定男孩的阴毛（PH）分期。比较每个年龄组和每个PH分期的平均实际年龄和根据GP图谱确定的平均骨骼年龄。
在7至13岁年龄组中，平均骨骼年龄分别比平均实际年龄延迟0.61、0.72、0.54、0.39、0.25、0.39和0.32岁，在14至17岁年龄组中则提前0.13、0.01、0.89和0.52岁。在PH分期1、2和3中，平均骨骼年龄分别比平均实际年龄延迟0.67、0.51和0.40岁。在PH分期4和5中，平均骨骼年龄比平均实际年龄提前0.66和0.76岁。
结果表明，土耳其男孩在青春期发育期间的骨骼成熟速度可能与制定GP标准所依据的美国儿童不同。因此，GP图谱不完全适用于土耳其男孩，但可以进行一些修改后使用。
