AB  - OBJECTIVE: To understand the normal lumbar spine in the sagittal plane, and the range of lumbar lordosis.METHODS: This study was carried out in the Department of Anatomy, School of Medicine, Duzce University, Duzce, Turkey in the year 2005. We retrospectively reviewed T1-weighed sagittal spin-echo MRIs of the lumbar spine in 413 individuals (188 male, 225 female) aged between 13-82 years, and evaluated the angle of lumbar lordosis (ALL), sacrohorizontal angle (SHA), and lumbosacral angle (LSA).RESULTS: The ALL and SHA were significantly greater in females than in males (p<0.05). Weak, but significant correlations were detected between age and ALL, SHA, and LSA for females (p<0.05). The LSA was significantly greater for individuals over 41 years (p<0.05) when the entire study group was considered, and it was also significantly greater for individuals over 51 years in females (p<0.05). The LSA was significantly greater in the 7th decade than in the 3rd decade (p<0.05).CONCLUSION: The results of this study provide insight into the sagittal alignment of the lumbar region for a Turkish population, and can serve as a reference for further clinical studies to improve the planning of spinal surgery.
