【摘要】：目的探讨CHN(中国人手腕骨发育标准CHN法)骨龄在司法鉴定中的应用价值,分析影响其准确性的因素及相关问题。方法对522例年龄鉴定者,均选用不同曝光值拍摄两张左手腕部正位X线片,并加照两次斜位片。使用CHN法测评骨龄。结果522例中男性489例,女性33例。男性达CHN骨龄最高值18.4岁者129例,余平均骨龄16.5岁。女性达CHN骨龄最高值17.3岁者14例,余平均骨龄15.7岁。CHN骨龄在16.0岁以上者共388例,占约74.3%。本组资料显示多种因素影响骨龄鉴定的准确性,其中以骨龄片位置及角度的变化等影响最大。结论如能获得高质量的X线片、并能熟练使用CHN法、注意利用位置和角度的变化正确判定骨骺分级,CHN骨龄基本可满足活体年龄鉴定的需要。
[Abstract]:Objective to explore the application value of CHN (Chinese wrist bone development standard CHN method) in forensic identification and analyze the factors affecting its accuracy and related problems. Methods two positive radiographs of left wrist and two oblique radiographs were taken from 522 patients with different exposure values. Bone age was measured by CHN method. Results there were 489 males and 33 females in 522 cases. The highest bone age of CHN was 18. 4 years old in male, and the average bone age was 16. 5 years old. The highest bone age of CHN was 17.3 years old in 14 women, and the average bone age was 15.7 years old in the rest. The bone age of CHN was over 16.0 years old in 388 cases (74.3%). The data showed that the accuracy of bone age identification was affected by many factors, especially the position and angle of bone age. Conclusion if high quality X-ray films can be obtained and CHN method can be skillfully used, epiphyseal grading can be judged correctly by using the changes of position and angle. The bone age of CHN can basically meet the needs of in vivo age identification.
