在正中矢状位图像上测量了L1和S1水平的硬脊膜囊的前后径和上终板角。
On midsagittal images, AP dural sac diameter and the upper-endplate angles of L1 and S1 were measured.
研究结果:我们发现41%(12/29)的受试者存在椎间盘的突变或者突出,但都未明显压迫硬脊膜囊。
Results. We found a disc degeneration or disc protrusion in 41% (12/29) of the subjects, but there was no obvious compression of the dural sac.
施加轴向负荷后,椎间盘的厚度在三个活动平面明显减少,同时,硬脊膜囊横断面积在11个平面减少,但不会出现在相同运动平面。
Significant reductions of disc height were found at 3 motion segments and of DCSA at 11 segments after compression, but these changes were never seen in the same motion segment.
