In the past, numerous studies have documented the possibility of intraindividual differing appearances of the paired age-marker "medial clavicular ossification" in borderline adults. However, the extent of the divergences is rarely mentioned. Against that the article describes this phenomenon from a large sample of 2595 male persons by means of thin-slice CT imaging of the sternoclavicular regions. For determining the ossification stage of the medial clavicles, the two accepted classifications by Schmeling et al. (five main stages) and Kellinghaus et al. (six substages) were applied and buildings deviating from that labelled as atypical "norm variants". The longstanding observation could be confirmed that intraindividual stage discrepancies of this age indicator are generally moderate and do not exceed one main stage or two substages of the respective classifications. It is concluded that stage determination should be scrutinized, if a dissimilarity seems to show larger differences.
过去，大量研究记录了临界成年人中配对的年龄标记物“内侧锁骨骨化”个体内部出现不同表现的可能性。然而，分歧的程度很少被提及。针对这一点，本文通过对2595名男性的胸锁关节区域进行薄层CT成像，从大样本的角度描述了这一现象。为了确定内侧锁骨的骨化阶段，应用了Schmeling等人（五个主要阶段）和Kellinghaus等人（六个子阶段）的两种公认分类方法，并将偏离该标准的结构标记为非典型“正常变异”。长期观察结果得到证实，即这个年龄指标的个体内部阶段差异通常是中等的，不超过各自分类中的一个主要阶段或两个子阶段。得出的结论是，如果差异似乎显示出更大的不同，则应仔细审查阶段确定情况。
