An array of diversity in sacral anatomy including lumbosacral transitional variations is commonly found in the general population. These anatomical variations involve alterations in number of sacral segments, auricular surface area, and neural arch dimensions and are associated with biomechanical, surgical and obstetric implications.
The present study reports screening >300 dried human sacral specimens and grouping them based on the common variations observed specifically in context of the number of sacral segments, position of the auricular surfaces, and type of the neural arch components.
Screening and grouping of the samples presented a five-group classification and coding system that incorporates specific structural characteristic in a sacrum.
The grouping and coding system developed in this study classifies variabilities associated with sacral anatomy along a common-to-rare anatomical spectrum that may provide handy information needed in a clinical, biomechanical, obstetric or medico-legal context.
在普通人群中，常发现一系列骶骨解剖结构的多样性，包括腰骶部移行变异。这些解剖变异涉及骶椎节段数量、耳状面面积和神经弓尺寸的改变，并与生物力学、手术及产科方面相关。
本研究报告了对300多个干燥的人类骶骨标本进行筛查，并根据在骶椎节段数量、耳状面位置以及神经弓组成类型等方面特别观察到的常见变异对其进行分组。
样本的筛查和分组呈现出一种五组分类和编码系统，该系统纳入了骶骨的特定结构特征。
本研究中开发的分组和编码系统沿着从常见到罕见的解剖学范围对与骶骨解剖相关的变异性进行分类，这可能会提供临床、生物力学、产科或法医学背景下所需的便捷信息。
