翻译后摘要：年龄估计在亚成年人的骨骼可以相当精确时，骨骺和牙列存在，但不完整或混合仍然是一个挑战。 开发用于成人的组织形态测定死亡年龄估计方法是基于骨单位的年龄相关蓄积。在生长的骨骼中，骨单位数量和年龄之间的相关性很差，直到第二个十年的后半段。因此，还没有用于亚成体的组织学老化方法。对72名年龄在2至21岁之间的亚成体肋骨皮质的分析已经确定了一系列可用于估计年龄的骨微结构的发育变化。 这种定性方法利用肋骨皮质形态的系统变化，肋骨分为四个年龄阶段之一。这种方法可以应用于法医，考古和古生物学背景下的未成熟骨骼。
Abstract: Age estimation in the subadult skeleton can be rather precise when the epiphyses and dentition are present, but incomplete or commingled remains still present a challenge. Histomorphometric age‐at‐death estimation methods developed for use on adults are based on the age‐associated accumulation of osteons. In the growing skeleton, there is a poor correlation between osteon numbers and age until the latter half of the second decade. As a result, there has been no histological aging method for use in subadults. The analysis of the rib cortex of 72 subadults ranging in age from 2 to 21 years has identified a series of developmental changes in the bone microstructure that can be used to estimate age. This qualitative method utilizes the systematic changes in rib cortical morphology to classify ribs into one of four age phases. This method can be applied to immature skeletons in forensic, archaeological, and paleontological contexts.
