摘要： 目的针对当代青少年膝、踝关节骨骺发育的特点,分析青少年骨骺生长发育的变化趋势,并探讨其在活体年龄鉴定中应用的可能性。方法摄取华东、华中、华南三地区1709名年龄介于11～21周岁两性青少年双侧膝、踝关节正侧位X线片,从上述关节中遴选出股骨远端、胫骨近端、腓骨近端、胫骨远端及腓骨远端骨5个骨骺作为骨骼发育指标,观察各个骨骺的发育情况;通过统计分析得出各骨骺在不同年龄组中处于骨骺闭合等级的比例,确定研究膝、踝关节骨骺闭合的纳入人群,并计算出每个骨骺闭合的年龄范围。结果与上世纪60年代的研究资料相比,5个骨骺闭合年龄提前约2～3岁;与本世纪初的其他研究相比,结果基本一致。结论利用骨骺闭合时间推断活体年龄所依据的数据得到有效更新,并对当代两性青少年年龄界定有重要的指导意义。

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 1 709 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.
