Abstract

The purpose of this article is to quantify changes in thickness of the ligamentum flavum (LF) associated with motion of the cervical spine and to compare the thickness of the LF at each cervical level using kinetic magnetic resonance imaging (kMRI). Two hundred fifty-seven symptomatic patients (129 men; 128 women) underwent kMRI in neutral, flexion, and extension positions. Midsagittal images were digitally marked and electronically analyzed by spine surgeons. Thickness of LF in the cervical region from C2-3 to C7-T1 was measured in all three positions. LF at C7-T1 was significantly thicker than C2-3 to C6-7 in neutral, flexion, and extension positions (p < 0.05). LF was significantly thicker in extension than in flexion at C3-4 to C6-7. LF thickness increases with extension and decreases with flexion. LF is uniquely thick at C6-7 and at C7-T1 in the extension position, which may predispose these levels to cord compression syndromes and associated neuropathies.

摘要

本文旨在量化颈椎运动时黄韧带（LF）厚度的变化，并使用动态磁共振成像（kMRI）比较每个颈椎水平的 LF 厚度。257 例有症状的患者（男性 129 例，女性 128 例）在中立位、前屈位和后伸位接受了 kMRI 检查。脊柱外科医生对正中矢状面图像进行了数字标记和电子分析。在所有三个位置测量了 C2-3 至 C7-T1 颈椎区域 LF 的厚度。在中立位、前屈位和后伸位，LF 在 C7-T1 处明显比 C2-3 至 C6-7 处厚（p<0.05）。在 C3-4 至 C6-7 处，LF 在伸展位比在屈曲位更厚。LF 随伸展而增加，随屈曲而减少。LF 在 C6-7 和伸展位的 C7-T1 处特别厚，这可能使这些水平容易发生脊髓压迫综合征和相关的神经病。
