侧向全脊柱放射线摄影是治疗脊柱畸形的有用工具，但放射线摄影期间最合适的手臂位置尚未确定。在这项前瞻性研究中，我们评估了 26 名成年志愿者和 22 名腰椎管狭窄患者。全脊柱侧位X光片是在受试者站立时双臂伸展，手轻轻地握在躯干前方（握紧位置）时，以最稳定和放松的姿势拍摄的。测量以下参数：矢状垂直轴（SVA）、腰椎前凸角（LLA）、骨盆角（PA）、骨盆前凸角（PRS1）、骨盆倾斜度（PT）和骨盆倾角（PI）。测量的可靠性通过组间相关系数进行评估。志愿者的 SVA 呈轻微阳性。 LLA、PA、PRS1、PT 和 PI 与标准正常值一致。结果显示，观察者内部和观察者间的可靠性“几乎完美一致”。扣紧位置可有效且可靠地用于测量成人腰部区域的矢状脊柱对准。
Lateral whole-spine radiography is a useful tool in the management of spinal deformity, but the most appropriate arm position during radiography has yet to be determined. In this prospective study, we evaluated 26 adult volunteers and 22 patients with lumbar spinal canal stenosis. Lateral whole-spine radiographs were acquired in the most stable and relaxed position while the subjects were standing with their arms extended and their hand gently clasped in front of the trunk (clasped position). The following parameters were measured: sagittal vertical axis (SVA), lumbar lordotic angle (LLA), pelvic angle (PA), pelvic lordosis angle (PRS1), pelvic tilt (PT), and pelvic incidence (PI). The reliability of measurements was assessed by interclass correlation coefficients. The SVA was slightly positive in volunteers. LLA, PA, PRS1, PT, and PI were compatible with standard normal values. The results showed “almost perfect agreement” with regard to intra- and interobserver reliability. The clasped position can be used effectively and reliably for measurement of sagittal spinal alignment for the lumbar region in adults.
