A Study of Dorsal Sacral Agenesis
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2018, Vol 3, Issue 8
Abstract
Background- Sacrum is a triangular shaped irregular bone formed by fusion of five sacral vertebrae. Sacrum is also called ‘Hieron osteon’ meaning the holy or sacred bone. Methods- This study was carried out in department of Anatomy and gynecology & obstetrics. 100 sacral bones from various Medical and Dental colleges of U.P & Rajasthan state were used for this study. Result-Elongated sacral hiatus i.e. length more than 20 mm was seen in 2 (2.00%) bones. Maximum sacral hiatal length of 51.7 mm was noted. Elongated sacral hiatus were of two types i.e. inverted U and inverted V shaped. 3 (3%) bones showed partial dorsal agenesis of sacrum. Complete dorsal agenesis was seen in 1.00 % sacra. one (1.00%) bones with absent sacral hiatus were seen. Conclusion- We conclude that, variant anatomy of dorsal wall of sacrum make administration of caudal epidural anaesthesia difficult. Keywords- Spina bifida, dorsal sacral agenesis, sacral hiatus, caudal epidural block.
