A Study of Canal Body Ratio of the Lumbar Vertebrae Measured in Antero-posterior Radiographs

For present study, anteroposterior radiographs of lumbar spine of three hundred adult subjects of Sonepat District were utilized. These radiographs were of known sex i.e. hundred & fifty males and hundred & fifty females and of known age group (between twenty five and forty years of age).

The parameters used in the study are transverse diameters of spinal canal, antero-posterior diameters of vertebral bodies. Making use of these parameters canal body ratio is calculated. The values less than the lower limits of the calculated range may be suggestive of spinal canal stenosis, while the values more than the upper limits of the calculated range may be suggestive of intraspinal tumor at that particular segmental level for males and females respectively.
