对于骶骨主要和次要骨化中心的融合时间知之甚少，特别是从干骨观察中。在这项研究中，这些中心结合的时间在一个现代葡萄牙骨骼样本中进行了研究（90名女性和101名男性），年龄在0到30岁之间，取自里斯本记录的骨骼收藏。采用三阶段方案评估骨化中心之间的融合状态，包括未融合、部分融合和完全融合。年龄的后验概率表，给定一定的融合阶段，计算了大多数解剖位置使用参考和统一的先验研究。在1 ~ 8岁时观察到初级骨化中心部分愈合，在15 ~ 21岁时观察到次级骨化中心部分愈合。完成融合的第一个主要骨化中心是神经弓与第五骶椎体的椎体，最后是肋部与第一骶椎体的椎体。在观察到的次要骨化中心中，环状骨骺和骶髂骨骺首先完成融合，然后外侧缘融合。该研究提供了发育中的骶骨不同位置融合时间的信息，有助于对完整或碎片化的未成熟人类骨骼遗骸进行年龄估计，并填补了文献中的一个重要空白，增加了先前发表的该样本中初级和次级骨化中心融合时间。[J] .中国生物医学工程学报，2014,33(3):344 - 344。(c) 2013 Wiley Periodicals, Inc.；
Little is known about fusion times of the primary and secondary centers of ossification in the sacrum, particularly from dry bone observations. In this study, the timing of union of these centers was studied in a sample of modern Portuguese skeletons (90 females and 101 males) between the ages of 0 and 30 years, taken from the Lisbon documented skeletal collection. A three-stage scheme was used to assess fusion status between ossification centers as unfused, partially fused and completely fused. Posterior probability tables of age, given a certain stage of fusion, were calculated for most anatomical locations studied using both reference and uniform priors. Partial union of primary centers of ossification was observed from 1 to 8 years of age and partial union of secondary centers of ossification was observed from 15 to 21 years of age. The first primary centers of ossification to complete fusion are the neural arch with the centrum of the fifth sacral vertebrae and the last are the costal element with the centrum of the first sacral vertebra. The annular and sacroiliac epiphyses are the first, among the secondary centers of ossification observed, to complete fusion, after which the lateral margin fuses. This study offers information on timing of fusion of diverse locations in the developing sacrum useful for age estimation of complete or fragmented immature human skeletal remains and fills an important gap in the literature, by adding to previously published times of fusion of primary and secondary ossification centers in this sample.
