Introduction: The lumbar vertebrae are five vertebrae between the rib cage and the pelvis. They are characterized by the absence of the foramen transversarium. This study conducted to measures the bony vertebral dimensions and to set the normal limits in assessing the lumber stenosis. Aim: study of lumbar vertebrae in population Of Gwalior region. Material and Methods: 250 lumbar vertebrae from L1 to L5 were taken for the measurement of different dimensions from the Anatomy department of GR Medical College Gwalior. Result and discussion: the mean transverse and anteroposterior diameter of vertebral body and the spinal canal were minimum in the L1 and gradually increases to L5 in both the sexes. The parameters are used for the measurement of spinal index of Jones and canal body ratio and hence it serves as a guide to spinal stenosis.. Conclusion: present study calculated spinal index which can aid in diagnosis of lumbar spinal stenosis.
