Abstract :

<p>&nbsp;Sacral Hiatus is an opening present at the lower end of sacral canal. The anatomy of sacral hiatus and its variations are clinically important during administration of Caudal Epidural Block (CEB) in Obstetrics and Gynaecology (OBGY) and General surgery practices. The success and reliability of CEB depends upon the sound knowledge of anatomical variations of sacral hiatus. Thus the present study was undertaken to find the variations in dry human sacra of southern region. Aim: To study the morphometry variations of sacral hiatus. Methods: 64 adult, grossly normal dry human sacra of southern origin were collected from anatomy department of various medical colleges in chennai. Results: Inverted U was the most common observed shape. The most common site of apex and base was observed at S4 and at the level of S5 respectively. Conclusion: The knowledge of variations in the shape, level and measurements of sacral hiatus will help in the effective and successful caudal epidural block (CEB) practices which are commonly used in surgical procedures.</p>
