ABSTRACT

Introduction: The opening present at the caudal end of sacral canal is known as sacral hiatus. It is formed due to the failure of fusion of laminae of the fifth (occasionally 4th) sacral vertebra. It is located inferior to the 4^th or 3^rd fused sacral spines or lower end of median sacral crest.
Material and Methods: This study was carried out on 60 dry human sacra in Hyderabad region of Telengana state, India to know the anatomical variations of sacral hiatus.
Result:  Various shapes of sacral hiatus were observed which included inverted- U (40%), inverted- V (45%), irregular (1.7%), dumbbell (1.7%) and bifid (1.7%). The apex of sacral hiatus was commonly found at the level of 4^th sacral vertebra in 55%. the mean length of sacral hiatus was 30.8 mm.  The mean anteroposterior diameter of sacral canal at the apex of sacral hiatus was 7.25 mm.
Conclusion: The knowledge of anatomical variations of sacral hiatus is significant while administration of caudal epidural anaesthesia and it may help to improve its success rate.
KEY WORDS: Sacral hiatus, Apex, Pelvic scral foramina, Caudal anaesthesia.
