Objective: To review the process of radiographic measurements of sagittal balance and offer reference for the clinical practice.
Methods: The related literature of spino-pelvic sagittal parameters and their clinical application was reviewed and analyzed from the aspects such as the clinical application, the advantages and disadvantages, and how to use them effectively.
Results: All parameters have their advantages and disadvantages, and they are influenced by age and race. Sagittal vertical axis can only reflect the global balance, and T 1 pelvic angle which accounts for both spinal inclination and pelvic tilt can't be controlled in the surgery. The correction goal for western people may be not suitable for Chinese.
Conclusion: The parameters should be used wisely when evaluating the sagittal balance, the global balance and local balance should be considered together and the different groups of people need different correction goals.
目的: 对骨盆-脊柱矢状位平衡的影像学评价现状及争议展开综述，为其在临床的合理应用提供参考。.
方法: 广泛查阅国内外关于骨盆-脊柱矢状位参数及其临床应用的相关文献，从目前常用的各项参数的临床应用、各自的优点和局限性、如何合理运用这些参数等方面进行总结。.
结果: 矢状位参数各有其优缺点，而且受种族、年龄影响。脊柱矢状轴仅能反映整体情况，T 1 骨盆角综合了躯干倾斜和骨盆代偿信息，但在术中不易控制，而西方人群的矫形目标可能不适合于中国人群。.
结论: 在评估矢状位平衡时需合理运用各参数的优势，衡量整体平衡时也需考虑局部情况，而且对于不同人群需要采用不同的评价标准。.
