Sacral hiatus is accessed for various reasons by the clinicians. The present morphological study was carried out on 50 dry human sacra collected from Dogra region of India , which comprises of the population with average height ranging from 160- 165 cm to ascertain the anatomical variations of sacral hiatus.The sizes of the sacral hiatus varied greatly and so did the shapes. The most common shape was inverted U in 32 %, followed by inverted V in 20% and irregular shapes .There were spina bifida in 4 % sacra .A“Dumb- bell” shaped sacral hiatus was observed in 10% cases with a nodular bony growth projecting medially from both margins and irregular shape in 10 % .
