Abstract：
BACKGROUND: In the sacrococcygeal region, anatomical variation is due to the sacralization of the coccygeal vertebra, which is the due union of/fusion of the fifth sacral with the first coccygeal vertebra of five couples of sacral foramina under-detected or asymptomatic beyond radiological assessment. That is why it is challenging to know the cause of coccydynia, caudal block failure, the difficult second stage of labor, and perineal tears. The present study aims to improve knowledge about the anatomical variation of sacralization of the coccygeal vertebra. Additionally, to find the prevalence of sacralization of coccygeal vertebra in Sylhet, Bangladesh.
METHODS: This study was performed on 60 parched, totally calcified, typical sacra of mature-age individuals of undetermined sexes, fulfilling the inclusion criteria from the bone bank of the osteology museum of the Department of Anatomy, Sylhet MAG Osmani Medical College, Sylhet, Bangladesh, from July 2017 to June 2018. Sex determination of the collected unknown sacra was conducted using discriminant function analysis. It was found that 50% (30) were male and 50% (30%) were female. The unpaired t-tests and chi-square were utilized to determine the statistical significance.
RESULTS: Out of 60 sacra, eight (13.33%) samples presented with sacralization. This study found that males had significantly higher straight (p=0.05) and curved (p=0.05) lengths of sacrococcygeal vertebrae. The sacrococcygeal curvature index (SCI) showed statistically significant (p=0.05) differences between the sexes.
CONCLUSIONS: Sacralization may exert an impact on the caudal block. It could extend the second stage of the labor process with perineal tears. Therefore, knowledge about the anatomical variation of the coccygeal vertebra is essential.

摘要：
背景：在骶尾部，解剖变异是由于尾骨椎骨的神圣化，这是第五骶骨与五对骶骨孔的第一尾骨的正确结合/融合，未发现或无症状，超出放射学评估。这就是为什么要知道尾骨痛的原因是具有挑战性的，尾部阻滞失败,艰难的第二阶段的劳动，和会阴的眼泪.本研究旨在提高对尾椎骶化解剖变异的认识。此外,为了发现Sylhet的尾椎骨化的患病率，孟加拉国。
方法：这项研究是在60个干，完全钙化,性别不确定的成熟年龄个体的典型圣事，符合解剖学系骨学博物馆骨库的纳入标准，SylhetMAGOsmani医学院，Sylhet,孟加拉国,从2017年7月到2018年6月。使用判别函数分析对收集的未知骶骨进行性别确定。发现50%(30)是男性,50%(30%)是女性。非配对t检验和卡方用于确定统计显著性。
结果：在60个萨克人中，八个（13.33%）样本呈现圣化。这项研究发现，男性的骶尾椎骨的直（p=0.05）和弯曲（p=0.05）长度明显更高。骶尾部弯曲指数（SCI）在两性之间显示出统计学上的显着差异（p=0.05）。
结论：圣化可能对尾部阻滞产生影响。它可以延长会阴撕裂的分娩过程的第二阶段。因此,了解尾椎的解剖变异是必不可少的。
