The author present a new method of assessment of bone age derived from the analysis of carpal osseous development of 5,225 Spanish children and adolescents. The method is based upon the determination of a carpal index from the measurement of the largest diameter of the eight carpal bones, the proximal epiphysis of the first metacarpal and the distal cubital and radial epiphyses. There is a highly significant correlation of this carpal index with chronological age (P < 0.0001). From this index the author has set up an equation defining an index of evaluation of carpal ossification which helps to estimate bone age according to six different ranges of significance: significant retardation, moderate non significant retardation, borderline normality, complete normality, moderate non significant advance, significant advance. The method is simple to realize. It reduces the risk of errors in the evaluation of bone age due to asynchronisms of maturation of the ossification centres and to the individual subjective factor occurring with a morphologic assessment. Furthermore it takes into account the physiological variations of bone age on both sides of the mean normal value.
作者提出了一种新的骨龄评估方法，该方法源自对5225名西班牙儿童和青少年腕骨发育情况的分析。该方法基于通过测量八块腕骨、第一掌骨近端骨骺以及尺骨远端和桡骨远端骨骺的最大直径来确定腕骨指数。此腕骨指数与实际年龄存在高度显著相关性（P < 0.0001）。基于该指数，作者建立了一个定义腕骨骨化评估指数的方程，该方程有助于根据六个不同的显著范围来估计骨龄：显著延迟、中度非显著延迟、临界正常、完全正常、中度非显著提前、显著提前。该方法易于实施。它降低了因骨化中心成熟不同步以及形态学评估中个体主观因素导致骨龄评估错误的风险。此外，它还考虑了骨龄在正常平均值两侧的生理变化。
