Introduction: Caudal block is now- a –days a commonly used procedure for pain management and regional anaesthesia. The optimum volume of drugs required to reach the appropriate level is needed.
Material and Methods: For this, we studied seventy-two human sacra and measured morphometrics like height of canal and transverse diameter. We utilized these measurements for volume estimation of sacral canal and caudal space by forming a simple mathematical formula for volume half-cone.
Results: We observed that mean volumes of sacral canal and caudal space were 38.26 cm3 (23.76-62.78 cm3) and 14.25cm3 (6.67-24 cm3) respectively.Volumes of sacral canal and caudal space had higher values in males than in females.
Conclusion: So, finally, it was concluded that volume of caudal space could be easily calculated this way and it was as reliable as MRI.
