目的:观察屈曲旋转腰椎牵引对人腰神经通道的断面解剖学影响。
方法:青壮年男尸8具,应用断层解剖学技术制作脊柱区L1～S1矢状面和冠状面断层标本,将得到的断层标本固定于模拟屈曲旋转牵引器上,每一标本摄像观察。
结果:在屈曲旋转腰椎牵引时,椎间隙增宽;椎间孔上2/3增大,下1/3减小;关节突关节面上下滑动、切向旋转、间隙增宽;黄韧带紧张;神经根在神经通道内被牵伸滑动,这种滑动在行旋转时以对侧神经根为显着。
结论:屈曲旋转腰椎牵引可通过增加椎间隙、扩大椎间管、纠正小关节功能紊乱、松解神经根粘连而起到治疗腰椎间盘突出的效果。 |

| Effect of flexion rotational traction on the canals of lumbar spinal nerves |

Abstract:
Objective:To study the effects of flexion rotational traction on lumbar nerve root canal
Methods: Samples of human lumbosacral spine L 1～S 1 from 8 adult cadavers were used in the experiment The sagittal sections were made by cryotomy through median sagittal plane,intervertebral foramena,zygapophyseal joints and coronal sections through zygapophyseal joints,intervertebral foramena and pediculus arcus vertebrae The samples were fixed on analog flexion rotational traction apparatus The changes of disc,foramen,zygapophyseal joint and ligmentum flavum of L 4～5 and L 5S 1 were observed
Results: During the traction,intervertebral space became wider,the upper two third of the intervertebral formanea became bigger and the lower one third became smaller;articular surfaces of zygapophyseal joints were sliding,rotating and the space became broadened;yellow ligament became tense;nerve roots in nerve root canal were moving because of traction
Conclusion: Flexion rotational traction had treatment effect on prolapse of lumbar intervertebral disc by widening intervertebral space,enlarging intervertebral canal,correcting dysfunction of zygapophyseal joints and relaxing adhesion of nerves. |
