Each vertebra is formed by combining the distal portion of one somite and the cranial half of its proximate part. genes regulate the patterning of the shapes of the non-identical spinal column. In the sacral area, anatomical dissimilarity is on account of the distinct shape of the sacral hiatus and the outright non-subsistence of the posticous embankment of the sacral neural tube, which is a consequence of the non-fulfillment of bonding of lamina of all sacral vertebrae. After that, the meninges and the spinal nerve are unprotected and undiagnosable without an X-ray examination. Therefore, it is difficult to detect the reasons for caudal block failure, low back pain, etc. The current research aimed to improve the proficiency of anatomical and developmental errors of the dorsal wall of the sacrum.
This study was conducted on 60 dried adult sacra of unknown sexes from the stock wing of Anatomy, Sylhet MAG Osmani Medical College, Bangladesh, from 2017 to 2018. The undefined gender of the sacrum was identified.
Out of 60 sacra, 30 (50.0%) were found to be that of males and 30 (50.0%) of females. Among the study samples, only three (5%) samples presented a complete absence of the sacrum's dorsal wall and and incidence among males was higher than females.
This type of sacral aberration has paramount clinical importance. Thereby avoiding caudal epidural block-connected sufferings and backbone operative procedures. The expertise regarding the anatomical variation of sacral hiatus is necessary to reduce the failure rate during caudal epidural anesthesia, helps orthopedic surgeons diagnose the cause of low back pain or in surgical situations, and helps pediatricians deal with congenital anomalies such as meningocele and myelomeningocele.
每个椎骨由一个体节的远端部分与其相邻部分的颅侧半部分结合而成。基因调控着形态各异的脊柱的形态模式。在骶骨区域，解剖结构的差异是由于骶管裂孔的独特形状以及骶神经管后堤的完全不存在，这是所有骶椎椎板未融合的结果。此后，在没有X线检查的情况下，脑膜和脊神经得不到保护且无法诊断。因此，很难检测到尾端阻滞失败、腰痛等的原因。当前的研究旨在提高对骶骨后壁解剖和发育异常的认识。
本研究于2017年至2018年对孟加拉国锡尔赫特MAG奥斯曼尼医学院解剖学储备库中60具性别不明的成人干燥骶骨进行。确定骶骨的性别不明情况。
在60具骶骨中，发现30具（50.0%）为男性，30具（50.0%）为女性。在研究样本中，只有三个（5%）样本完全没有骶骨后壁，男性的发生率高于女性。
这种类型的骶骨畸形具有至关重要的临床意义。从而避免与尾端硬膜外阻滞相关的痛苦和脊柱手术。了解骶管裂孔的解剖变异对于降低尾端硬膜外麻醉期间的失败率、帮助骨科医生诊断腰痛的原因或在手术情况下以及帮助儿科医生处理诸如脊膜膨出和脊髓脊膜膨出等先天性异常是必要的。
