ABSTRACT:

Introduction: Sacral hiatus (SH) is a significant landmark during caudal epidural block (CEB) which is employed for analgesia and anaesthesia during a wide range of clinical conditions. This requires a thorough knowledge of morphometric characteristics of SH and surrounding landmarks, but variability in morphometric dimensions exists among different populations.

Aim: The aim of this study was to identify different anatomical landmarks to detect the location of SH and provide a reference database for morphometric dimensions of SH in Indian population.

Materials and Methods: The study was done on 108 dry adult human sacra. Linear measurements of the sacra were taken with the help of digital vernier caliper and angular parameters were determined with a goniometer.

Results: The most common shape of the sacral hiatus was inverted ’V’ shaped (59.3%) with the level of the apex at S4 in 66.7% and base at S5 in 86.1% cases. Morphometric dimensions of SH were found to be smaller in present study as compared to reports by other researchers. Left crest-apex angle was observed to be significantly greater than the right crest-apex angle. (p˂0.001).

Conclusion: Multiple bony landmarks and their morphometric dimensions should be considered to locate the SH during CEB. Values for various morphometric parameters of SH are less in Indians in comparison to other populations, which should be contemplated during caudal epidural injections and trans-sacral thecaloscopy.

Key words: Bony landmarks, Morphometric dimensions, Caudal epidural block, Caudal epidural injection, Sacral hiatus.
