Histomorphometrische Analyse der Tangentiallamellenbucht (Endosteal Lamellar Pocket, ELP), Archäologische Bedeutung lokalisiert auftretender Variationen innerhalb der Compacta auf mikrostruktureller Ebene.

在横截面内，密质骨的形态可以显示微结构的显著变化，从而显示强度特性。骨内膜板层袋（ELP）是长骨的一个易于定义的致密板层区域，可能是这些区域中最明显和最具信息性的（Wanner等，2007; Maggiano等，2008 b; Maggiano等，2008 a）。我们之前的初步研究确定了在Xcambó玛雅遗址发现的大多数股骨和肱骨中的ELP。我们认为ELP的形成可能与20岁之前的生长期相吻合，并且由于未知的原因，持续了几十年，记录了骨干在生长过程中的漂移。ELP的形成和持久性的这一历时观点对于区分骨建模（骨吸收和形成）和重塑（骨维持）对其宏观和微观结构的影响至关重要。不幸的是，长骨建模和建模漂移的分析是罕见的，而重塑研究利用不同的代表性结构，称为骨单位，精确地允许定量方法的方法。ELP可以被认为是组织学上代表可量化建模过程的特征。然而，个体发育过程中漂移的相对大小和方向以及新骨沉积的组成尚未与决定性因素（如生长速度、疾病、年龄、性别或活动水平）相联系。像这样的联系可以为考古学中的假设驱动实验提供新的来源，以及关于骨骼生长，维护和适应生物力学或医学应用的信息。我们将继续研究ELP在考古和现代骨骼遗骸中的作用，并将利用这一独特的长期生长和建模过程指标，寻找ELP分析的应用及其在生物力学、生物考古学和法医学中的应用，帮助分析生长变化、机械适应以及鉴定方法，包括壁板、年龄估计、甚至可能是从零碎的骨头残骸中判断出性别。

Within a cross section, the morphology of compact bone can display dramatic variation in microarchitecture and therefore strength properties. The endosteal lamellar pocket (ELP), an easily-defined, dense, lamellar region of the long bone is perhaps the most obvious and informative of these regions (Wanner et al. 2007; Maggiano et al. 2008b; Maggiano et al. 2008a). Our previous pilot study identified ELPs in the majority of femora and humeri found at the Maya site of Xcambó. We suggest the formation of the ELP could coincide with periods of growth before about twenty years of age and, for unknown reasons, persists for decades, documenting the diaphysis’ drift during growth. This diachronic perspective of the ELP’s formation and persistence is ultimately vital for differentiating the influences of bone modeling (bone resorption and formation) and remodeling (bone maintenance) on its macro- and microstructure. Unfortunately, analyses of modeling and modeling drift in long bones are rare, whereas remodeling studies take advantage of distinct representative structures, called osteons, precisely permitting quantitative methodological approaches. The ELP can be recognized as a feature histologically representing quantifiable modelling processes. However, the relative magnitude and direction of drift and the composition of new bone apposition during ontogenetic development has yet to be connected to determinant factors such as growth rate, disease, age, sex, or activity level. Connections like these could offer a new source for hypotheses driven experimentation in archaeology as well as information regarding skeletal growth, maintenance, and adaptation for biomechanical or medical applications. Our continued investigation of the ELP in archaeological and modern skeletal remains will take advantage of this unique indicator of long-term growth and modelling processes to find applications for ELP analyses and its use in biomechanics, bioarchaeology and forensics, aiding in analyses of growth variation, mechanical adaptation, as well as identification methods including siding, age estimation, and possibly sex determination from even fragmentary bony remains.
