Background: The sacral hiatus, a crucial anatomical structure in the sacrum, exhibits considerable morphological and morphometric variability among individuals. Understanding these variations is essential for clinical interventions such as epidural anesthesia and surgical procedures involving the sacral region.Materials and Methods:This study examined the morphological and morphometric variations of the sacral hiatus in dry human sacra. A total of 50 dry human sacra were obtained from anatomical collections. Various parameters including length, width, shape, and presence of additional bony landmarks were measured using digital calipers (accurate to 0.1 mm).Results: The study revealed diverse morphological configurations of the sacral hiatus. The length of the hiatus ranged from 1.5 cm to 3.5 cm among the examined dry human sacra, with an average length of 2.8 cm. The width varied from 0.5 cm to 1.5 cm, with an average width of 1.0 cm. Various shapes of the hiatus were observed, including triangular, inverted U-shaped, irregular, and oval. The presence of additional bony landmarks such as the median sacral crest extending into the hiatus, sacral cornu, and transverse ridges was also noted.Conclusion: The findings highlight the significant morphological and morphometric diversity of the sacral hiatus among dry human sacra. Understanding these variations is crucial for clinical procedures involving the sacral region, aiding in the accurate localization of anatomical structures and minimizing procedural complications.
