Abstract: The spinal-pelvic sagittal parameters are a hot topic in spinal surgery, but the biomechanical mechanism remains unclear. With the increasing incidence of lumbar degenerative diseases, researches on the lumbar sagittal alignment have shown that a variety of lumbar degenerative diseases are closely related to sagittal imbalance. Therefore, 山 东 大 学 学 报 (医 学 版)57卷5期 -赵杰,等.腰椎矢状位力线分型及临床意义 \=-restoring and reconstructing the physiological curvature is essential to maintain the normal biomechanical functions of lumbar spine. Investigating the characteristics of spinal sagittal alignment and the degenerative trend can help doctors to reversely deduct the pathological condition, and to reconstruct the physiological sagittal alignment, which may alleviate the degeneration of adjacent segments. However, due to various influencing factors and complex spinal compensatory mechanism, our cognition is still limited, and more remains to be done to explore the spinal pelvic parameters and sagittal alignment.

Key words: Sagittal alignment, Lumbar spine, Degeneration
