Objective: A prospective study of several radiographic parameters of sagittal profile of the spine was conducted to determine the clinical values of these parameters. Methods: The lumbar lordotic curve was measured as Lumbar Lordotic Angle (LLA), Lumbosacral Angle (LSA), Sacral Horizontal Angle (SHA) and our suggested new parameter, Lumbar Sagittal Balance Axis (LSBA). We compared the association between LLA, LSA, SHA and LSBA in 100 patients with chronic low back pain (LBP) and 100 control group. Results: LSA was statistically significant in male ones in patients and control group (P=0.0001) but this angle didn’t showed a significant difference without the effect of gender. SHA angle didn’t show any statistical significance in patients with LBP. A significant correlation was observed between LSBA increase and LBP (P=0.001). Conclusion: Measurement of LSAs and LSBAs may provide orthopedic surgeons some appropriate parameters to predict acute to chronic LBP transformation risks.
