Background: The causes of low back pain are multi-factorial, but the narrowing of the lumbar canal plays a significant role. Lumbar Spinal Canal Stenosis is considered to be the main etiology of lumbar pain. The present study was conducted to compare the transverse diameter of lumbar vertebral body and canal in males and females. Materials & Methods: The present study included 10 subjects of both genders. Their lumber radiographs were collected and studied. In all radiographs, the transverse diameter of vertebral body (TDVb) and transverse diameter of vertebral canal (TDVc) was measured from L1 to L5 vertebral levels. Results: The mean TDVb at L1 (Males- 37.22, females- 36.1), L2 (Males- 38.44, females- 38.32), L3 (males- 39.64, females- 39.08), L4 (males- 42.38, females- 40.01) and L5 (males- 42.38, females- 42.15). The difference was non- significant (P>0.05). The mean TDVc at L1 was (males- 26.7, females- 28.25), L2 (males- 26.9, females- 28.6), L3 (males- 27.5, females- 28.6), L4 (males- 28.25, females- 30.12) and L5 (males- 28.29, females- 30.57). The difference was non- significant (P>0.05). Conclusion: We concluded that there is no significant difference in the transverse diameter of lumbar vertebral body and lumbar vertebral canal in males and females.
