Study on Revisiting Sacral Hiatus
Recent Research Advances in Biology Vol. 11,
5 July 2021
Sacral hiatus is caudal opening of sacral canal. Caudal epidural anaesthesia for various therapeutic and diagnostic procedures is administered through sacral hiatus. 25% failure rate of caudal epidural block has been reported in literature. The failure rate of this procedure may be due to variant anatomical features of sacral hiatus. Hence knowing the anatomical variations in shape, size, level of apex and base of sacral hiatus is of paramount importance to clinicians to reduce failure rate of caudal epidural block. The anatomical features of sacral hiatus are of immense value to orthopaedic surgeons, obstretricians, paediatricians, anaesthecians and anatomists. Aim of study is to update and consolidate the information on sacral hiatus as this updated and consolidated information on sacral hiatus in this chapter will serve a ready reference for future researchers and clinicians.
