The FELS method of assessing the skeletal maturity of the hand-wrist differs from the Greulich-Pyle and Tanner-Whitehouse methods in the observations made, the provision of a range of shapes to which maturity indicator grades can be assigned and in the statistical methods used to construct the scale of skeletal maturity. The FELS method for the hand-wrist was developed using 13,823 serial radiographs of the left hand-wrist of boys and girls in the Fels Longitudinal Study. One hundred-thirty possible indicators were originally identified. Eighty-five graded and 13 metric indicators were selected on the basis of an indicator's ability to discriminate between children at the same chronological age, its universal appearance, reliability, validity, and completeness. The subset of FEELS maturity indicators assessed at a chronological age are analyzed with a microcomputer program that provides the skeletal age and the standard error of the estimate for that skeletal age. Comparison among hand-wrist skeletal age assessments for children in the Fels Longitudinal Study by the FELS, Greulich-Pyle, and Tanner-Whitehouse methods indicate that the FELS method is the more appropriate method for the present population of United States children.
FELS评估手腕骨骼成熟度的方法与Greulich - Pyle法和Tanner - Whitehouse法不同，体现在观察内容、提供可赋予成熟度指标等级的一系列形状以及用于构建骨骼成熟度量表的统计方法上。FELS手腕评估方法是利用Fels纵向研究中男孩和女孩左手腕的13823张系列X光片开发的。最初确定了130个可能的指标。基于指标区分同一年龄儿童的能力、其普遍出现情况、可靠性、有效性和完整性，选择了85个分级指标和13个度量指标。通过一个微机程序分析在实足年龄评估的FELS成熟度指标子集，该程序可提供骨骼年龄以及该骨骼年龄估计值的标准误差。Fels纵向研究中儿童手腕骨骼年龄评估采用FELS、Greulich - Pyle和Tanner - Whitehouse方法进行比较，结果表明FELS方法更适合美国目前的儿童群体。
