腰椎椎板切除术是将受累部位的椎板切除，以解除神经根或马尾神经的压迫，缓解由此引起的下肢疼痛、麻木、无力、大小便功能障碍等神经症状。

Spinal stenosis is caused by degenerative changes that lead to enlargement of the facet joints in the back of the vertebrae. The enlarged joints and related degenerative changes place pressure on the nerve roots as they exit the spine. 腰椎椎板切除术通常用于缓解腰椎管狭窄所致的疼痛。腰椎管狭窄往往由于退行性变导致腰椎后方的关节突关节肥大而引起。增生的关节和相关退行性改变对即将离开脊柱的神经根造成压迫。 Each vertebra has two portions of vertebral bone over the nerve roots in the back of the spine. These small flat bones are called the lamina. 在脊柱后方，每个脊椎骨在神经根后方都有两片扁平的骨头，称为椎板。 The lamina functions as a protective covering of the spinal canal. In the lower back, they protect the cauda equina, the nerve roots that branch off of the spinal cord, as well as the nerve roots as they exit the spine. 椎板的功就象椎管的保护盖。在腰椎，它们保护从脊柱分支出来的马尾神经以及在离开脊髓时的神经根。 Removing all or part of the lamina through a lumbar laminectomy can give the affected nerve root more space and a better healing environment. 通过腰椎椎板切除术将部分或全部椎板去除，可以为受累神经根提供更多的空间和更好的愈合环境。 In a laminectomy surgery, the spine is approached through a 2 to 5 inch incision in the midline of the lower back. 在椎板切除术中，从腰部的后正中作2~5英寸的切口进行显露。 Next the left and right back muscles, called erector spinae, are dissected off the lamina on both sides and at multiple levels. 然后将背部左右两侧称为竖脊肌的肌肉，从两侧多个节段的椎板上剥离下来。 After the spine is approached, the lamina is removed, allowing visualizaion of the nerve roots. 当脊柱显露完毕，就可将椎板切除，这样就可以清楚地看到神经根。 The facet joints, which are directly over the nerve roots, may then be undercut, or trimmed, to give the nerve roots more room. 可能需要将神经根正后方的关节突关节边缘切除或修整，给神经根以更多的空间。 After the surgeon has confirmed that all pressure has been removed from the nerve, the paraspinal muscles are sewn back together to cover the laminectomy site. 术者确认神经的压迫彻底解除，将两侧棘旁肌缝在一起，覆盖椎板所在的位置。 After the lamina and any other sources of pressure on the nerve roots are removed, the nerve roots have room to heal. 当椎板及其它压迫神经根的组织被去除后，神经根就有了恢复的空间。 （胡佰文 译） 精彩视频魅力无限，收藏转发一起分享 您的每一次打开，都会有精彩的内容 您的每一次留言，都会有满意的答复 您的每一次点赞，都是对我们的肯定 您的每一次分享，都是对我们的鼓励 世界多姿多彩 感谢有您相伴 |
