Address for Correspondence: Dr. R. Senthamizhselvi M.D.(Anatomy), Assistant Professor, Department of Anatomy, Chengalpattu Medical College, Chengalpattu, Tamilnadu, India. Contact no.: 9080637507, E-Mail: senrajselvi@gmail.com Background and Aims: The sacral hiatus is formed by the failure of lamina of the fifth sacral vertebra to meet in the median plane. The aim is to study the sacral hiatus, as the effectiveness of caudal epidural anaesthesia depends on the knowledge in anatomy of sacral hiatus and its variations. Materials and Methods: In this study 107 sacral bones of unknown sex are obtained from Chengalpattu medical college in Tamilnadu and studied under various parameters like shape, apex, base, length, width and anteroposterior diameter of the sacral hiatus using vernier caliper of accuracy 0.1mm. Results: The maximum number of sacra exhibits Inverted ‘U’ shaped sacral hiatus, with apex at S4 and base at S5. The average length, width and anteroposterior diameter are between 11-20mm, 11-15mm and 5-6mm respectively. Two sacra had absent sacral hiatus and 5 sacra had completely unfused lamina. Conclusion: Caudal epidural anaesthesia is impossible in persons with absent sacral hiatus. Completely unfused sacrum and abnormally elongated sacral hiatus can result in accidental subdural injection and subarachanoid injection. The size and shape of sacral hiatus varies considerably. The awareness of such variations is essential for the clinicians during caudal epidural approaches.
