Background: The sacrum is a vital bone in the human skeleton, essential for forming the pelvic girdle and providing stability to the body. Its anatomy has significant clinical applications in Orthopedics and anesthesiology. This study investigates the dimensions and measurements of the sacrum to aid in sex determination and improve the efficacy of caudal epidural blocks, ultimately enhancing clinical practices related to this important skeletal structure. Methods: The present study was conducted on 110 dry human sacra within one and a half years. Sacra of unknown sex morphometric parameters data were collected from medical colleges of central India. After getting permission from the institutional ethics committee, this study was conducted by the Department of Anatomy, Index Medical College, Hospital and Research Centre, Indore, Madhya Pradesh.The dry sacral bones, which were ossified entirely without any visible variation or damage, were taken for study purposes. All the measurements were performed by using a Vernier digital calliper with an accuracy of 0.1mm. The measurements were recorded, and their mean and standard deviations were calculated. Results: This study found that the mean values of sacrum width and length were higher in males than in females. Conclusion: The sacral index, along with the maximum sacral length and width, were the most significant parameters for identifying sex. Additionally, understanding the anatomical variations of the sacral hiatus may enhance the success rate of caudal epidural anesthesia.
