未成年人案件中两种骨龄测定法的应用价值的初步研究

目的研究未成年人骨龄与实际年龄和刑事责任年龄间的关系,探讨顾氏图谱法、李果珍骨龄百分计数法在未成年人涉嫌犯罪案件中的应用价值。方法选择33位身体健康、发育正常的未成年人(12～19岁),拍摄左手腕部X线片,分别使用顾氏图谱法、李果珍骨龄百分计数法测定每张X线片的骨龄,再将骨龄与受试者实际年龄比较,用行平均分检验分析两法推测未成年人实际年龄的精确性,用Pearson检验分析两法推断未成年人刑事责任年龄的准确性。结果李果珍骨龄百分计数法推测实际年龄的精确性高于顾氏图谱法(P<0.005);而二者推断刑事责任年龄的准确率分别为90.91%和78.79%,统计学分析结果无显著性差异(P>0.1)。结论两种方法均适用于未成年人涉嫌犯罪案件,基本满足法律实施的要求。

Preliminary study on the applying value of two measurements for bone age in the cases of minors

OBJECTIVE: To research the connection of the minor's bone age and chronological age and age for penal responsibility, to discuss the application of Gu's Atlas and Li Guozhen's Percent Numeration to measure the bone age in the cases of immature criminals and the applying value. METHODS: 33 healthy youths, 12-19 years old, were selected, whose left wrists were photographed with X-rays. According to the radiographic appearance of the maturity indicators, the bone age of every person was determined respectively by the Gu's Atlas and Li Guozhen's Percent Numeration, and then compared with his/her chronological age. CMH test and Pearson test were used to evaluate precision and accuracy on concluding the immature age for penal responsibility. RESULTS: Li Guozhen's Percent Numeration was more precise than Gu's Atlas on extrapolating the chronological age of the youth, P<0.005. On extrapolating the age for penal responsibility, the accuracy of the former was 90.91%, and the latter was 78.79%, but the statistic result did not show significant difference (P>0.1). CONCLUSION: Both measurements can apply in determining the criminal cases of immature youths.
