脊柱平衡分析已经变得越来越重要，并且放射学脊柱骨盆参数的测量现在是许多脊柱手术干预的常规部分。实际上，腰椎前凸的手术矫正必须与骨盆倾角（PI）成比例。手术成功后，代偿机制[骨盆后倾，骨盆倾斜增加（PT）和胸椎后凸减少]自发逆转。本研究首次从白人（n = 137）和日本（n = 131）无症状受试者的大型数据库中提供了3D站立脊柱骨盆参考值。日本和高加索人群的PI、PT、骶骨斜率（SS）]相当。在线性回归建模后计算了三个方程，即基于PI的腰椎前凸、基于PI的PT和基于PI的SS，并且在两个人群中具有可比性：腰椎前凸（L1-S1）= 0.54*PI + 27.6，PT = 0.44*PI - 11.4和SS = 0.54*PI +11.90。我们发现，从大型健康受试者数据库中获得的关键脊柱骨盆参数在高加索人群和日本人群中具有可比性。本研究提供的标准值和线性回归模型后得到的方程可以帮助术前估计腰椎前凸恢复，也可以用作脊柱骨盆矢状面平衡的指南。
Sagittal balance analysis has gained importance and the measure of the radiographic spinopelvic parameters is now a routine part of many interventions of spine surgery. Indeed, surgical correction of lumbar lordosis must be proportional to the pelvic incidence (PI). The compensatory mechanisms [pelvic retroversion with increased pelvic tilt (PT) and decreased thoracic kyphosis] spontaneously reverse after successful surgery.This study is the first to provide 3D standing spinopelvic reference values from a large database of Caucasian (n = 137) and Japanese (n = 131) asymptomatic subjects.The key spinopelvic parameters [e.g., PI, PT, sacral slope (SS)] were comparable in Japanese and Caucasian populations. Three equations, namely lumbar lordosis based on PI, PT based on PI and SS based on PI, were calculated after linear regression modeling and were comparable in both populations: lumbar lordosis (L1-S1) = 0.54*PI + 27.6, PT = 0.44*PI - 11.4 and SS = 0.54*PI + 11.90.We showed that the key spinopelvic parameters obtained from a large database of healthy subjects were comparable for Causasian and Japanese populations. The normative values provided in this study and the equations obtained after linear regression modeling could help to estimate pre-operatively the lumbar lordosis restoration and could be also used as guidelines for spinopelvic sagittal balance.
