There exist a direct correlation between the dimension of the spinal canal and its associated consequences after trauma. The dimensions of the canal can influence the possibility whether an individual will suffer prolonged effect, after a spinal injury in that area. And it will also influence the recovery time. Dimensions of dry bones of vertebrae can easily be obtained. However, from clinical point of view, obtaining the dimensions of vertebrae in livings is more important. So, in the present study, normal lateral radiographs of cervical spine of three hundred Western Maharashtra adult subjects with known age and known sex were studied. Third to seventh cervical vertebrae were studied in the present study. The parameters used in the study are viz.  anteroposterior diameters of spinal canal and vertebral bodies. Making use of anteroposterior diameters of spinal canal and vertebral bodies, canal body ratio (Torg�s ratio) was calculated. It was observed that the anteroposterior diameters of cervical spinal canal and vertebral bodies showed sexual dimorphism. Comparison of these vertebral dimensions with corresponding dimensions from other ethnic groups showed evidence of racial variation. These parameters can be used as reference values for evaluating various clinical conditions like spinal stenosis and intraspinal tumours in the cervical spine in Western Maharashtra population.
