目的描述当前我国14岁青少年手腕骨发育特征,并初步评估14岁的青少年骨发育的变化趋势。方法以湖南娄底地区14岁青少年为对象(男53人,女56人),拍摄左手腕部X线片,参照顾氏图谱法描述各选定观察部位并分析发育特征,将统计结果与顾氏图谱法14岁骨龄标准进行比较分析。结果与顾氏法相比,男生组桡骨远端、第1掌骨近端和近节第4指骨骨骺发育程度较高,而女生组桡骨远端、第2～5掌骨、第1～5近节指骨和第2～5中节指骨骨骺发育程度较高。结论当前我国14岁青少年骨发育存在提前趋势,在女生组尤为显著。14岁是刑事责任年龄点之一,法医推断该年龄时应注意该特征对推断结果的影响。
Objective To describe the characteristics of the wrist bones of 14-year-old adolescents in our country and to evaluate the changing tendency of adolescent bone development at 14 years old. Methods The 14-year-old adolescents in Loudi, Hunan Province (53 males and 56 females) were enrolled in this study. The left wrist radiographs were taken. The selected observation sites were described according to Gu’s diagram and the developmental characteristics were analyzed. Atlas of 14 years of age by bone map standard comparative analysis. Results Compared with the Gu’s method, the male students had a higher degree of development of the distal radius, the proximal end of the first metacarpal and the fourth phalanx of the proximal segment, while the distal radius of the female students, the second to fifth metacarpal, the proximal phalanges from the first to the fifth And the second to the 5th phalanx epiphysis high degree of development. Conclusion At present, there is an early trend in the bone development of 14-year-old adolescents in our country, especially in girls group. At the age of 14, one of the age points of criminal responsibility, the forensic extrapolation of this age should pay attention to the impact of this feature on the inferred outcome.
