摘　　要：目的探讨司法鉴定中骨龄小于"年龄"的现象和可能原因。方法参考中国人手腕骨发育标准CHN法附带的检验样本所提供的骨龄验证值,结合鉴定时公安机关提供的"年龄"、"户籍"等相关资料,并追踪回访部分案例,对829例使用CHN法行骨龄司法鉴定资料进行回顾性分析。结果骨龄小于"年龄"共303例,占(303/829)36.6%,在742例有"年龄"案例组中占(303/742)40.8%。如以两者差值小于0.5岁(含0.5岁)为正常范围内计则降至190例,所占比例为(190/829)22.9%和(190/742)25.6%。差值在0.5岁以内时与骨龄值相近的"年龄"可信度最高,在0.6～2.0岁时难以确定何者有误,但随差值增大"年龄"有误可能性上升。"年龄"和骨龄本身诸多不确定因素均可导致骨龄小于"年龄",并可能是多种因素共同影响的结果。结论在鉴定实践中骨龄小于"年龄"发生率不低;鉴定结论以综合评估后谨慎使用为宜。Objective To discuss the phenomenon and the possible causes for the skeletal age less than the ＂real age＂ in the judicial expertise. Methods With referring to the skeletal age verification value provided by the inspection sample pertaining to CHN scoring method, combining with the relevant materials such as ＂age＂ and ＂residence＂ information provided by the police authority while performing expertise, as well as tracking down and re-visiting some cases, we retrospectively analyzed 829 cases. Results There were 303 cases for the skele- tal age less than ＂real age＂ in total, which accounted for 36.6% （303/829）, and accounted for 40.8% （303/742） in 742 cases with ＂age＂ cases. If the normal age range between both was less than 0.5 year （including 0.5）, the numbers of such cases decreased to 190 cases, which accounted for 22.9% （190/829） and 25.6% （190/742）, respectively. When the difference was within 0.5, the ＂age＂ close to the skeletal age would be more reliable. It was difficult to confirm which one was wrong if the difference was 0.6-2.0 years. However, the error possibility in ＂age＂ would increase with increasing the difference value. Conclusion Many uncertain factors may lead to that the skeletal age was less than the ＂age＂. The occurring rate for the skeletal age less than ＂age＂ is not low. The identification conclusion shall be made with caution after comprehensive assessment.
