To outline the variations in morphology and a few clinically relevant morphometric parameters of the sacral hiatus.
The study included 50 dry human sacra, of unspecified sex, in the Department of Anatomy at a medical college in South India. The sex was determined using the sacral, auricular and curvature index. The variations and morphometry of the sacra were documented and tabulated.
It was observed that the inverted U shape of sacral hiatus was common in both males (n=24) and females (n=26). There was one female sacrum with complete dorsal wall agenesis. In males, the length of the apex of sacral hiatus from 1st sacral spine was 5.82 cm ± 1.27 and in females, it was 6.02 cm ± 1.08. Sacral hiatus depth in males was 0.56 cm ± 0.16 and in females 0.54 cm ± 0.14. The width of sacral hiatus at the cornua in males was 1.42 cm ± 0.29 and in females, it was 1.46 cm ± 0.38 CONCLUSION: Knowledge of incidences of variations in the morphology and morphometry of the sacral hiatus across various population groups is paramount for the success and reliability of epidural anesthesia. The success rate of such procedures depends on the clinicians' understanding of the discrepancy in the sacral hiatus.
概述骶骨裂孔形态和一些临床相关形态参数的变化。
本研究纳入了印度南部一所医学院解剖系的 50 具未指明性别的干燥人骶骨。使用骶骨、耳状和曲率指数确定性别。记录和列表记录骶骨的变异和形态。
观察到骶骨裂孔的倒 U 形在男性（n=24）和女性（n=26）中均很常见。有一具女性骶骨的整个背壁发育不全。在男性中，骶骨裂孔顶点距第 1 骶骨棘的长度为 5.82cm±1.27，而在女性中为 6.02cm±1.08。男性骶骨裂孔深度为 0.56cm±0.16，女性为 0.54cm±0.14。男性骶骨裂孔角宽为 1.42cm±0.29，女性为 1.46cm±0.38。
了解不同人群骶骨裂孔形态和形态参数的变异发生率对于硬膜外麻醉的成功和可靠性至关重要。这些手术的成功率取决于临床医生对骶骨裂孔差异的理解。
