Abstract

Study Design

Observational Study

Objective

The primary objective was to determine if there were differences in spine structure measures between experimental postures and standard supine posture MRIs.

Methods

Thirty-four low back pain patients were included. MRI was taken in 6 experimental postures. The dependent measures includes sagittal view anterior (ADH), middle and posterior disc heights, thecal sac width, left/right foraminal height (FH). In the axial view: disc width, left and right foraminal height. Measures were done L3/L4, L4/L5 and L5/S1. Each subject served as their own control. Spine measurements in the experimental posture were compared to the same measures in the standard supine posture.

Results

94% inter-observer reliability was seen. In the sagittal and axial view, 55 of the 108 and 11 of the 18 measures were significantly different. In sagittal view: a) ADH was significantly smaller in the sitting flexed posture by 2.50 mm ± 0.63 compared to the supine posture; b) ADH in sitting neutral posture was significantly smaller than the standard posture by 1.97 mm ± 0.86; c) sitting flexed posture showed that bilateral FH measures were significantly different; d) Bilateral FH was larger in the sitting neutral posture compared to the standard supine posture by 0.87 mm ± 0.17.

Conclusions

This research quantifies the differences in spine structure measures that occur in various experimental postures. The additional information gathered from an upright MRI may correlate with symptoms leading to an accurate diagnosis and assist in future spine research.

腰椎测量的差异作为腰痛患者 MRI 姿势的函数及其临床意义

摘要

学习规划

观察性研究

客观的

主要目的是确定实验姿势和标准仰卧姿势 MRI 之间的脊柱结构测量是否存在差异。

方法

包括 34 名腰痛患者。MRI以6个实验姿势进行。相关测量包括矢状面前部 (ADH)、中部和后部椎间盘高度、鞘囊宽度、左/右孔高度 (FH)。轴位观:椎间盘宽度、左右椎间孔高度。测量进行了 L3/L4、L4/L5 和 L5/S1。每个受试者作为他们自己的对照。将实验姿势的脊柱测量值与标准仰卧姿势的相同测量值进行比较。

结果

观察者间可靠性达到 94%。在矢状面和轴向视图中,108 项中的 55 项和 18 项中的 11 项存在显着差异。在矢状视图中: a) 与仰卧位相比,坐屈位的 ADH 显着小 2.50 mm ± 0.63;b) 中立位坐姿的 ADH 明显小于标准姿势 1.97 mm ± 0.86;c) 坐屈姿势表明双侧 FH 测量值有显着差异;d) 与标准仰卧位相比,中立位坐姿双侧 FH 大 0.87 mm ± 0.17。

结论

这项研究量化了各种实验姿势中脊柱结构测量的差异。从直立式 MRI 收集的额外信息可能与导致准确诊断的症状相关,并有助于未来的脊柱研究。
