    Introduction: Sacrum is a large roughly triangular bone forming the caudal end of the vertebral column. Sacral hiatus (SH) is a foramen present at the caudal end of sacral canal. Knowledge of actual shape and size of SH and its variations play a major role in accomplishing needle placement during administration of caudal epidural. In this study, we aim to evaluate and analyze the sacral index with reference to SH morphometrically and to correlate it with its clinical applications. Materials and Methods: A total of 30 dry human disarticulated sacral bones were obtained, and the shape of SH was observed and analyzed. Length of hiatus was measured from apex of hiatus to the midpoint of the base. AP diameter of SH at the apex was also measured. Distance between the two superolateral sacral crests (AB), distance between the right superolateral sacral crest and apex of SH (AC), and distance between the left superolateral sacral crest and apex of SH (BC) were measured. Results: Inverted V shape, 53.33%, was the most common shape of SH. Highest percentage of the sacral level of apex of SH was at S4 with 62.48%, and the highest percentage of the sacral level of base of SH was at S5 with 81.25%. Length of SH ranged from 11 to 20 mm comprising 41.25% as the highest. Mean distance between the right and left superolateral sacral crest (AB), right superolateral sacral crest and apex of SH (AC), and left superolateral sacral crest and apex of SH (BC) was 67.5 mm, 65.0 mm, and 65.0 mm, respectively. Conclusion: Understanding the variations of sacral index with reference to SH may throw light on the difficult procedures and practices involved in caudal epidural anesthetic block.
