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 cm(3) (23.76-62.78 cm(3)) and 14.25cm(3) (6.67-24 cm(3)) 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.

In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...
