OBJECTIVE
The study aimed to establish the spinal cord occupation rate of the dural sac during flexion and extension.
METHODS
We measured the cross-sectional area of the dural sac and the spinal cord between C2/C3 and C7/T1 disc levels in 100 patients with cervical spondylotic myelopathy and 1211 asymptomatic subjects.
RESULTS
The spinal cord occupation rate of the dural sac in the cross-sectional area was higher on extension than on flexion at the mid-lower cervical spine.
CONCLUSIONS
The spinal cord occupation rate of the dural sac in the cross-sectional area was highest at the C4/C5 and C5/C6 levels on extension.
目的
本研究旨在确定屈伸过程中硬脊膜囊的脊髓占有率。
方法
我们测量了100例脊髓型颈椎病患者和1211例无症状受试者在C2/C3和C7/T1椎间盘水平之间的硬脊膜囊和脊髓的横截面积。
结果
在下颈椎中部，硬脊膜囊横截面积的脊髓占有率在伸展时高于屈曲时。
结论
伸展时，硬脊膜囊横截面积的脊髓占有率在C4/C5和C5/C6水平最高。
