摘要： 目的 运用薄层CT扫描探索四川汉族青年锁骨胸骨端骨骺发育状况及其与生活年龄的关系。 方法 结合Schmeling等提出的骨发育分级法，并考虑本研究样本的年龄区间，将锁骨胸骨端骨骺发育分为4个等级。依据上述骨骺发育等级阅读565例15~25周岁青年胸部薄层CT片，并对锁骨胸骨端骨骺发育状况进行统计学描述性研究。 结果 两性之间各级别骨龄的差异无统计学意义（P>0.05）。同时，经验分布函数显示，评定为1级者100%小于18周岁，评定为2级者75%小于18周岁，评定为3级者超过94.5%大于18周岁，评定为4级者100%大于20周岁。 结论 锁骨胸骨端骨骺发育在18周岁左右呈现一定规律。据此，可应用薄层CT扫描评估锁骨胸骨端骨骼年龄，为18周岁刑事责任年龄的判定提供依据。

Abstract: Objective To explore the growth status of epiphysis of sternal end of clavicle using thin-section computed tomography（CT） and to study the relationship between the status and the chronological age of Sichuan Han nationality youth. Methods According to the Schmeling’s report and the age range of our samples, the ossification status of medial clavicle epiphysis was classified as four stages. CT films of 565 patients between 15 and 25 years were studied based on the classification and analyzed statistically. Results There was no statistical difference between the sexes（P>0.05）. The calculated empiric distribution function showed that 100% of stage 1 patients were under 18 years, 75% of stage 2 patients were under 18 years, 94.5% of stage 3 patients were over 18 years, and 100% of the stage 4 patients were over 20 years, respectively. Conclusion The ossification of medial epiphysis of the clavicle for those around 18 years has certain regular. These characteristics can be used for forensic identification of the skeletal age, especially 18 years, which is the criminal responsibility age.
