Reaching the age of 18 years is the most significant step for criminal proceedings in China. In this study, a population of 752 individuals was recruited to clarify how strong the chronological age relates to clavicular ossification status revealed by CT scans with 1 mm slice thickness in the West China Han population. Finally, the epiphysis was observed to commence fusion in females at 16.28 years and 16.74 years in males and be fully ossified by 25.97 years in females and 25.81 years in males. These findings suggested that ossification of medial clavicular epiphyseal cartilage can be used in age estimation for West China Han population with the age threshold of 18 years. By comparison with previous German studies, our results suggested that the pace of ossification of medial clavicular epiphyseal cartilage may be potentially affected by socioeconomic status.
在中国，年满18岁是刑事诉讼中最重要的一步。在本研究中，招募了752名个体，以阐明在中国西部汉族人群中，实际年龄与1毫米层厚CT扫描显示的锁骨骨化状态之间的关联强度。最终观察到，女性锁骨骨骺开始融合的年龄为16.28岁，男性为16.74岁；女性锁骨完全骨化的年龄为25.97岁，男性为25.81岁。这些发现表明，中国西部汉族人群锁骨内侧骨骺软骨的骨化可用于年龄估计，年龄阈值为18岁。与之前德国的研究相比，我们的结果表明，锁骨内侧骨骺软骨的骨化速度可能受到社会经济地位的潜在影响。
