The opening present at the caudal end of sacral canal is known as sacral hiatus. The aim of this study is to determine the anatomical variations of sacral hiatus in dry human sacra in southern Nigeria. This study was carried out on 54 dry human sacra in southern Nigeria. Various shape of the hiatus were observed which includes inverted U- shape (24.1%), inverted V-shape (33.3%), irregular (13.0%), Dumbbell (9.3%) and Bifid (5.6%). The apex of sacral hiatus was commonly found at the level of 4th sacral vertebra in 66.7%. The mean length of sacral hiatus was 23.65mm. The mean anteroposterior diameter of sacral canal at the apex of sacral hiatus was 6.11mm.

In conclusion, the sacral hiatus has anatomical variations and understanding of these variations may improve reliability of caudal epidural block.

Keywords: sacral hiatus, dry human sacra, southern Nigeria.
