目的对常用骨龄评定方法进行比较分析,以评价其在判定骨龄精确度、实用性等方面的差别,为法医办案提供参考。方法选取河南省某县145名女性青少年作为研究对象,拍摄全身左侧六大关节X线片870张。分别采用百分计数法、CHN法、六大关节法、图谱法、叶氏评分法评定145名个体骨龄。采用SPSS ver.11.5软件包进行统计、分析。结果 CHN法、六大关节法、图谱法评定的骨龄与时间年龄无显著性差异(P>0.05);百分计数法和叶氏评分法评定的骨龄与时间年龄有显著性差异(P<0.05)。CHN法、六大关节法、图谱法评定的骨龄之间无显著性差异(P>0.05),百分计数法、叶氏评分法评定的骨龄相互之间及与其他方法之间存在显著性差异(P<0.05)。结论六大关节法评定女性青少年的骨龄精确度最高,CHN法和图谱法评定我国女性青少年骨龄较实用。
Objective To compare and analyze the commonly used methods of bone age assessment in order to evaluate their differences in the accuracy and practicability of bone age assessment and provide reference for forensic case handling. Methods A total of 145 female adolescents in a county of Henan Province were selected as the research object, and 870 X-rays of the six major joints of the left side of the body were taken. The bone age of 145 individuals was evaluated by the percentage counting method, CHN method, six-joint method, the mapping method and the Yip’s score method respectively. SPSS ver.11.5 software package for statistical analysis. Results There was no significant difference between the age of bone age and the time of CHN, six-node and histopathological evaluation (P> 0.05). There was significant difference between the age of bone age and percentage of time (P <0.05) ). There was no significant difference in CHD, CHD, BMD and BMD between the two groups (P> 0.05). There was significant difference between the skeletal age assessed by the percentage method and YEH score and other methods (P <0.05). Conclusion The six-joint method is the most accurate in assessing the skeletal age of female adolescents. It is more practical to assess the skeletal age of female adolescents by CHN method and the mapping method.
