Abstract

OBJECTIVE

According to the features of epiphyseal development of knee and ankle joints in male and female teenagers, the trend of epiphyseal development was analyzed and the possibility of its application in age estimation was discussed.

METHODS

Firstly, radiographs of adem position were taken from both sides of knee and ankle joints from 1709 individuals from Eastern China, Central China, and Southern China (Age: 11-21 years old). Secondly, 5 osteal loci were selected as bone age markers from the two joints. Thirdly, characteristics of epiphyseal development were observed systematically and comprehensively. Fourthly, the proportions of "epiphyseal fusion" in different age groups were calculated, and confirmed the numbers of people which were included by epiphyseal fusion of knee and ankle joints. Finally, age range of each epiphyseal fusion was calculated by mathematical statistical analysis.

RESULTS

Compared with the data of 1960s', the age of 5 epiphyseal fusions was earlier about 2-3 years. However, the results were basically the same as the recent studies.

CONCLUSION

The data on the time of epiphyseal fusion were updated. It is important to determine the accuracy in age estimation in male and female teenagers.

摘要

目的

根据男女青少年膝关节和踝关节骨骺发育特点，分析骨骺发育趋势，探讨其在年龄估计中的应用可能性。

方法

首先，对来自中国东部、中部和南部的1709名个体（年龄11 - 21岁）的膝关节和踝关节两侧进行正位X线片拍摄。其次，从这两个关节中选择5个骨位点作为骨龄标记。第三，系统全面地观察骨骺发育特征。第四，计算不同年龄组“骨骺融合”的比例，并确定膝关节和踝关节骨骺融合所涵盖的人数。最后，通过数学统计分析计算每个骨骺融合的年龄范围。
