锁骨的胸骨端已被证明对老年年轻人有用，但是，没有研究调查骨骺融合后胸骨端发生了哪些与年龄相关的变化。在这项研究中，使用来自四个记录在案的骨骼收藏中的 564 个欧洲血统个体（n = 318 名男性；n = 246 名女性）的锁骨（n = 318 名男性；n = 246 名女性）对三种形态特征（即表面形貌、孔隙度和骨赘形成）进行了检查和评分，这些人的年龄已知为 40 岁以上，这些骨骼来自四个记录在案的骨骼收藏：Hamann-Todd、比勒陀利亚、St. Bride's 和 Coimbra。为这三个特征中的每一个特征开发了顺序评分方法。表面形貌显示出与年龄最强的相关性，并且综合得分（通过将三个单独的性状得分相加而形成）表明随着实际年龄的增加，表面逐渐退化。对性状评分进行线性回归分析，以生成合并样本年龄估计方程。对来自 Christ Church Spitalfields 的 56 名 40 岁以上个体进行的综合评分法和回归公式的盲测表明，两种方法的准确度均为 96.4%。这些初步结果显示了锁骨胸骨端在老年个体中的实用性的第一个证据。然而，在目前的格式中，这些标准应仅适用于已确定为 40 岁以上的个人，以细化高龄的年龄范围。这些发现确实表明锁骨的胸端有可能帮助估计超出传统成熟成人年龄类别（即 46 岁以上）的年龄，并为未来的研究提供了一些建议。 Am J Phys Anthropol 156:203-214, 2015。(c) 2014 年作者美国体质人类学杂志由 Wiley periodicals, Inc. 出版。
The sternal end of the clavicle has been illustrated to be useful in aging young adults, however, no studies have investigated what age-related changes occur to the sternal end post epiphyseal fusion. In this study, three morphological features (i.e., surface topography, porosity, and osteophyte formation) were examined and scored using 564 clavicles of individuals of European ancestry (n=318 males; n=246 females), with known ages of 40+ years, from four documented skeletal collections: Hamann-Todd, Pretoria, St. Bride's, and Coimbra. An ordinal scoring method was developed for each of the three traits. Surface topography showed the strongest correlation with age, and composite scores (formed by summing the three separate trait scores) indicated progressive degeneration of the surface with increasing chronological age. Linear regression analyses were performed on the trait scores to produce pooled-sample age estimation equations. Blind tests of the composite score method and regression formulae on 56 individuals, aged 40+ years, from Christ Church Spitalfields, suggest accuracies of 96.4% for both methods. These preliminary results display the first evidence of the utility of the sternal end of the clavicle in aging older adult individuals. However, in the current format, these criteria should only be applied to individuals already identified as over 40 years in order to refine the age ranges used for advanced age. These findings do suggest the sternal end of the clavicle has potential to aid age estimates beyond the traditional mature adult age category (i.e., 46+ years), and provides several suggestions for future research.
