Sagittal alignment of the spine significantly affects the physical function. In this article, we review the clinical application of several spinal-pelvic parameters, analyze the impact factors of sagittal alignment and provide calculating methods to value the correcting degrees. Spine surgeons should get a deep understanding of the spinal-pelvic parameters, differentiate the functional and structural imbalance. Every patient needs thorough preoperative evaluation to restore the proper alignment during surgery and avoid overcorrection.
脊柱的矢状位平衡状态对于机体的功能具有重要的意义。本文回顾性分析了多项脊柱骨盆参数在临床中的运用，探讨了脊柱矢状位曲线的影响因素，并总结了多种矫形度数的估算方法。脊柱外科医师应当加深对于脊柱骨盆参数的理解，区分功能性失衡与结构性失衡，对于手术患者应通过详细的术前计划恢复合适的矢状位曲线，避免过度矫形的发生。.
