Abstract：
UNASSIGNED: Cervical foraminal stenosis on MRI may be assessed using the Kim, modified Kim or Siller methods. This study aimed to investigate which morphological features of cervical foraminal stenosis in patients with cervical radiculopathy correlated best with pre-operative and post-operative surgical outcome following Anterior Cervical Discectomy (ACD) or a Posterior Cervical Foraminotomy (PCF).
UNASSIGNED: Pre-operative MRIs of adults with cervical radiculopathy were assessed by six raters. The following measurements were made; uncompressed nerve root diameter, maximal compressed nerve root diameter, anterior & posterior compression, length of the neuroforaminal canal where the diameter was less than the uncompressed nerve root diameter and the distance of maximum compression from the apex of the ligamentum flavum. The Kim, modified Kim and Siller grades were calculated. Neck Disability Index (NDI) was measured pre-operatively and six weeks post-operatively. The radiological measurements and grades were compared to the pre-operative and change in NDI.
UNASSIGNED: Mean NDI was higher in female (58.2) than male patients (45.6) p = 0.05. No other baseline, operative or radiological factors where significantly associated with the pre-operative NDI. The mean [±SD] post-operative NDI was 14.3 [±22.5]. This represents a change of 37.8 (p < 0.001). The pre-operative NDI correlated strongly with the post-operative NDI but no other patient, operation or radiological factors correlated significantly. Neither pre-operative NDI or change in NDI was statistically different in those treated with ACD and those treated with PCF.
UNASSIGNED: There was no association between pre-operative NDI and any of the radiological measurements or radiological grades. Furthermore, whilst surgery significantly improved NDI, for those patients with anterior compression, there was no difference in outcome between those treated with an ACD and those treated with a PCF. Current axial MRIs do not adequately assess the cervical nerve root foramina or predict surgical approach, 3D isotropic acquisition and DTI should be explored.

摘要：
■MRI上的颈椎椎间孔狭窄可以使用Kim进行评估，修改了Kim或Siller方法。本研究旨在探讨颈神经根病患者的颈椎间孔狭窄的形态学特征与前路颈椎间盘切除术（ACD）或后路颈椎间孔切开术（PCF）的术前和术后手术结果最佳相关。
■六个评估者评估了成人神经根型颈椎病的术前MRI。进行了以下测量：未压缩的神经根直径，最大受压神经根直径，前后受压,神经椎间孔管的长度，其直径小于未压缩的神经根直径和最大压缩距离黄韧带顶点的距离。Kim,计算了修改后的Kim和Siller等级。术前和术后6周测量颈部残疾指数（NDI）。将放射学测量值和等级与术前和NDI的变化进行比较。
■女性患者的平均NDI（58.2）高于男性患者（45.6），p=0.05。无其他基线,与术前NDI显著相关的手术或放射学因素。术后平均[±SD]为14.3[±22.5]。这代表37.8的变化(p<0.001)。术前NDI与术后NDI有很强的相关性，但没有其他患者。手术或放射因素显著相关。ACD治疗和PCF治疗的患者的术前NDI或NDI变化均无统计学差异。
■术前NDI与任何放射学测量或放射学等级之间没有关联。此外，虽然手术显著改善了NDI，对于那些患有前压迫的患者，ACD治疗者和PCF治疗者的结局无差异.当前的轴向MRI不能充分评估颈神经根孔或预测手术入路，应探索3D各向同性采集和DTI。
