摘要

研究设计：回顾性横断面研究。目的通过常规和新的全球-区域参数分析印度无症状人群的脊柱-骨盆矢状面整体对中。方法：我们纳入了18 - 50岁无脊柱手术史或明显肌肉骨骼疾病的无症状成年人。矢状面按照Roussouly理论分类进行分类。采用Surgimap测量常规和新型脊柱参数。采用Pearson相关系数进行相关分析。结果共招募参与者104人，其中女性62人，男性42人。3AP型是最常见的Roussouly理论分类，占28.8%。分析新骨盆参数的平均值为：骨盆倾角（PI）： 45.433°±9.72°，L1骨盆角（PA）： 5.240°±6.7°，T1坡度：26.260°±8.24°，C7坡度：23.073°±8.35°，C2坡度：2.308°±11.42°，T4−L1骨盆角（PA）： 2.10°±3.797°，全局倾斜（GT）： 15.029°±10.80°。PI与新的参数如T4骨盆角（PA）和L1 PA相关。此外，PT与GT、Spino骨盆角（SPA）、Spino骶骨角（SSA）和T1−L1骨盆角（PA）有良好的相关性。最后，SVA C7−S1与齿状突-髋关节轴（ODHA）密切相关。本研究全面分析了印度无症状人群中传统与新的区域和整体矢状面脊柱参数之间的相关性。在本研究中阐明的印度志愿者矢状面轮廓的规范数据可用于指导手术决策。

Comprehensive analysis of global spinopelvic alignment based on traditional and new parameters in normal Indian population

Study Design: A retrospective cross-sectional study.

Purpose

To analyze the global sagittal spinopelvic alignment in the asymptomatic Indian population through the conventional and new global-regional parameters.

Methods

We included asymptomatic adults between 18 and 50 years old without a history of spinal surgery or significant musculoskeletal disorders. The sagittal profile was classified according to the theoretical Roussouly classification. The conventional and new spinopelvic parameters were measured using Surgimap. Correlation analysis was performed using Pearson’s correlation coefficient.

Results

104 participants (62 females and 42 males) were recruited. The type 3AP was the most common theoretical Roussouly classification at 28.8 %. Analyzing the new spinopelvic parameters, the mean values are Pelvic Incidence (PI): 45.433° ± 9.72°, L1 Pelvic Angle (PA): 5.240°± 6.7°, T1 Slope: 26.260°± 8.24°, C7 Slope: 23.073°± 8.35°, C2 Slope: 2.308°± 11.42°, T4 − L1 Pelvic Angle (PA): 2.10° ± 3.797°, Global Tilt (GT): 15.029° ± 10.80. PI correlated with the new parameters such as T4 Pelvic Angle (PA) and L1 PA. Furthermore, PT had a good correlation with GT, Spino Pelvic Angle (SPA), Spino Sacral Angle (SSA), and T1 − L1 Pelvic Angle (PA). Finally, the SVA C7 − S1 strongly correlates with the Odontoids – Hip Axis (ODHA).

Conclusion.

This study comprehensively analyzes the correlations between conventional and new regional and global sagittal spinal parameters in the asymptomatic Indian population. The normative data for the sagittal profile in Indian volunteers enunciated in this study can be used to guide surgical decisions.
