摘要
本文报告了10例正常人尸体腰椎标本脊髓造影屈/伸侧位片的测量结果。以观察腰椎屈伸活动对腰骶硬膜囊位置与形状的影响。结果表明,腰椎由屈曲位转为伸展位时,硬膜囊矢状径和长度均明显减小,硬膜囊尾端向下移动,硬膜囊前间隙矢状径在椎体中平面减小,椎间平面增大。本文还讨论了硬膜囊的动态变化及其影响因素和临床意义。
In order to analyse the effects of flexion-extension motion of lumbar spine on the position and shape of lumbosacral dural sac, measurements were performed on 10 flexion/extension lateral myelograms of cadaver specimens of normal lumbar spine.It could be seen that from flexion to extension both sagittal diameter and length of the dural sac increased significantly, the dural sac moved caudally, and the sagittal diameter of the anterior epidural space decreased in the mid-vertebral level but increased in the inter vertebral level.The dynamic changes of the dural sac, the influence factors and the clinical relevances were discussed.
