Introduction – The size and shape of cervical spinal canal is very important in cases of spinal cord or nerve root

compression. The normal values in the available literature are mostly from studies in western population. The

documented normal values in Indians are very few. This work is designed to measure the midsagittal diameter of cervical spinal canal and to

calculate canal/body ratio in the population in and around Jabalpur. Material and method – 100 sets of dried cervical verteae of cadavers of adult

age group, stored in the department of Anatomy, NSCB Medical College, jabalpur were taken for the study. Midsagittal diameter of cervical

verteal canal (A), anteroposterior diameter of verteal body (B) and Torg‘s ratio (A/B) were calculated. Results – The mean value of midsagittal

diameter (in mm) at third, fourth, fth and sixth cervical verteal canal was observed to be 14.38, 14.40, 14.36 and 14.55 respectively. The mean

value of Torg‘s ratio at third, fourth, fth and sixth cervical verteal level was observed to be 1.04, 1.02, 1.01 and 1.01.
