研究设计。对 160 名没有脊柱疾病症状的志愿者进行了前瞻性放射学研究。 目的。本研究的目的是描述、量化和分类脊柱、骶骨和骨盆矢状排列的常见变化。背景数据摘要。以前的出版物已经记录了脊柱矢状对齐的高度可变性。其他研究表明，排列的特定变化和腰椎前凸的特征是导致退行性变化和症状性背痛的原因。方法。在这项研究过程中，我们以标准化站立姿势拍摄了 160 名志愿者的前后位和侧位 X 光片。使用定制的计算机应用程序来分析侧位X光片上脊柱和骨盆的对齐情况。使用矢状形态的四部分分类方案对每位患者进行分类。结果。骶骨方位、骶骨坡度、骨盆倾角和腰椎前凸特征之间的相互关系很明显。整体脊柱前凸曲率、脊柱前凸倾斜角度、顶点位置以及脊柱前凸的数量由S1上终板相对于水平轴的角度确定。结论。了解矢状排列的变化模式可能有助于发现脊柱平衡与脊柱退行性变化之间的关联。
Study Design. A prospective radiographic study of 160 volunteers without symptoms of spinal disease was conducted.Objectives. The objective of this study was to describe, quantify, and classify common variations in the sagittal alignment of the spine, sacrum, and pelvis.Summary of Background Data. Previous publications have documented the high degree of variability in the sagittal alignment of the spine. Other studies have suggested that specific changes in alignment and the characteristics of the lumbar lordosis are responsible for degenerative changes and symptomatic back pain.Methods. In the course of this study, anteroposterior and lateral radiographs of 160 volunteers in a standardized standing position were taken. A custom computer application was used to analyze the alignment of the spine and pelvis on the lateral radiographs. A four-part classification scheme of sagittal morphology was used to classify each patient.Results. Reciprocal relationships between the orientation of the sacrum, the sacral slope, the pelvic incidence, and the characteristics of the lumbar lordosis were evident. The global lordotic curvature, lordosis tilt angle, position of the apex, and number or lordotic vertebrae were determined by the angle of the superior endplate of S1 with respect to the horizontal axis.Conclusions. Understanding the patterns of variation in sagittal alignment may help to discover the association between spinal balance and the development of degenerative changes in the spine.
