The objectives of this study were to evaluate the manubriosternal joint (MSJ) to estimate the minimum chronological age of complete fusion, and how changes in this joint influence age estimation. The study also focused on investigating the calcification patterns of the second costal cartilage (SCC), as they may be related to age. Between January and September 2020, individuals between 30 and 80 years of age, who underwent chest tomography at our institution, were listed by sex and divided into five groups according to age with intervals of 10 years. Twenty patients from each age group and sex were randomly selected, and 200 patients were evaluated. The relationship between age and changes in MSJ and SCC was evaluated. The incidence of complete fusion did not differ significantly between the 30 and 80 age groups. A significant difference was found between the age groups and MSJ degeneration (p < 0.001). The degree of MSJ degeneration and calcification in SCC significantly increased with age, but the range was wide. These values might be used to support traditionally accepted age-estimation methods but not as independent indicators of specific age ranges.
本研究的目的是评估胸骨柄体关节（MSJ）以估计完全融合的最小实足年龄，以及该关节的变化如何影响年龄估计。该研究还着重调查第二肋软骨（SCC）的钙化模式，因为它们可能与年龄有关。在2020年1月至9月期间，对在我们机构接受胸部断层扫描的30至80岁个体按性别进行列表，并根据年龄以10年的间隔分为五组。从每个年龄组和性别中随机选择20名患者，共评估了200名患者。评估了年龄与MSJ和SCC变化之间的关系。30岁和80岁年龄组之间完全融合的发生率没有显著差异。在年龄组与MSJ退变之间发现了显著差异（p<0.001）。MSJ退变程度和SCC钙化程度随年龄显著增加，但范围较宽。这些值可能用于支持传统上公认的年龄估计方法，但不能作为特定年龄范围的独立指标。
