摘    要:目的研究我国当前青少年手腕骨发育状况,探讨制定专用于法医学推断女性刑事责任年龄14岁的骨龄标准。方法以湖南冷水江地区青少年为对象,按照纳入标准,选取14岁±3个月的健康女性中学生110名,拍摄其左手腕部后前位X线片。选择手腕骨15个部位,按照统一标准进行观察、测量,采用最大百分比法确定发育等级标准,建立骨龄评估方法,以单盲法进行验证。结果桡骨,中排第三、第四指骨干骺端发育等级为部分闭合(〉2/3为主),其余掌指骨干骺端发育等级则以完全闭合残留骺线痕迹为主;对于中排第三、四指骨,不足14岁和已满14岁发育等级尚存差异,不足14岁组骨骺发育以部分闭合(〉2/3为主)为主,已满14岁组则以残存骺线痕迹为主。各个观察部位骨骺横径宽于干骺横径。30例的验证结果准确率为83.3%。结论根据发育等级特征及测量学方法建立骨龄标准准确性较好。

Abstract:Objective To study the current development of hand-wrist bones of adolescents in China, and establish special forensic bony age standard for estimating 14 years of criminal responsible age in female adolescents. Methods One hundred and ten healthy girls aged from 13 years and 9 months to 14 years and 3 months in Lengshuijiang district of Hunan province were enrolled in this study. X-ray films of their left hand-wrists were taken dorsaventrally, and 15 sites on the wrist x-ray films were examined and measured under standard condition. The development grade was confirmed by maximal percentage to establish a method to estimate the bony age, which was then checked by single blind method. Results Development grade of the radius, the middle third phalanx and the fourth phalanx was partially closed (〉2/3), and the rest was wholly-closed with existence of the epiphyseal line. The development grade of the middle third phalanx and fourth phalanx was different between the younger group (〈14 years, partially closed, 〉2/3) and the older group (〉14 years, mostly closed with existence of only epiphyseal line). The cross diameter of the osteoepiphysises were wider than that of all the diaphysises. The confirmed accuracy (in 30 girls) was 83.3%. Conclusion Our study seemes to be feasible in establishing the estimation standard for bony age determination. The standard established by developmental metaphysis and authropometry may be particularly helpful in forensic practice for estimation of accurate criminal responsible age in adolescents.
