The objective of this study was to compare three methods with which to determine the skeletal maturity of children.
The methods were Greulich & Pyle's atlas method based on hand-wrist radiographs (1959), and the cervical vertebrae methods based on lateral cephalograms of Lamparski (1972) and San Roman et al. (2002). We evaluated hand-wrist radiographs and the lateral cephalograms of 392 children (195 girls and 197 boys age 7-18). The morphology of the second (C2), third (C3) and fourth (C4) cervical vertebrae was assessed and the stage of skeletal maturity determined along with chronological age.
Our results revealed a significant correlation (p <or= 0.05) between the skeletal maturity of the cervical vertebrae and the skeletal maturity of the hand. The correlation coefficients between the skeletal maturity of the cervical vertebrae and chronological age were obviously lower. The correlation coefficients were higher when using the method of San Roman et al. (2002) rather than Lamparski's method (1972).
Our results show that in assessing skeletal maturity, the lateral cephalogram can replace the hand-wrist radiograph, thus reducing the patient's exposure to radiation.
本研究的目的是比较三种用于确定儿童骨骼成熟度的方法。
这些方法包括基于手腕部X光片的格罗利希和派尔图谱法（1959年），以及基于兰帕尔斯基（1972年）和圣罗曼等人（2002年）的头颅侧位片的颈椎方法。我们评估了392名7至18岁儿童（195名女孩和197名男孩）的手腕部X光片和头颅侧位片。评估了第二颈椎（C2）、第三颈椎（C3）和第四颈椎（C4）的形态，并确定骨骼成熟阶段以及实际年龄。
我们的结果显示颈椎的骨骼成熟度与手部的骨骼成熟度之间存在显著相关性（p≤0.05）。颈椎的骨骼成熟度与实际年龄之间的相关系数明显较低。使用圣罗曼等人（2002年）的方法时相关系数高于兰帕尔斯基（1972年）的方法。
我们的结果表明，在评估骨骼成熟度时，头颅侧位片可以替代手腕部X光片，从而减少患者的辐射暴露。
