髓管节

Cervical spondylosis is due to cervical back muscle strain as well as the unbalanced paravertebral muscle strength caused by long-term working with head drop, which thereby leads to a set of syndrome: cervical intervertebral disc degeneration, narrow intervertebral space, unstable vertebrae unit, protruded or extruded nucleus pulpous; hyperosteogeny, ligament pachynsis, narrow neural canal or nerve root canal; oppressed nerve root and spinal cord, stimulated vertebral artery and sympathetic nerve; aching and discomfort cervix; numbness and disability of the body; functional disorder in relieving the bowels; dizziness and nausea, etc.

颈椎病的原理及颈椎功能锻炼的原理 Theory of Cervical Spondylosis and Cervical Vertebrae Dirigation 颈椎病是由于长期低头工作等原因所导致的项背肌劳损、颈椎周围肌群肌力不平衡，从而使颈椎间盘退变、椎间隙狭窄、椎节失稳、髓核脱出或突出、骨质增生、韧带肥厚，使椎管或神经根管狭窄，压迫脊髓、神经根、刺激椎动脉及交感神经，出现颈部酸痛不适、躯体麻木无力、大小便功能障碍、头晕恶心等症状的一组综合症。

One patient had recurrent intramedullary ependymoma at the C3-T2 level.

一名患者在C3-T2节段再发了髓内室管膜瘤。

When surgery is indicated after central cord injury in the stable spondylotic spine, it is the overall cervical spinal alignment and the number of levels affected that determine the surgical approach.30 When the spine is lordotic, and particularly when there are multiple levels of compression; a posterior approach, either a laminectomy and fusion or a cervical laminoplasty are recommended approaches.28 If the spine is neutral or slightly kyphotic, then occasionally, after a posterior laminectomy, lordosis may be achieved with intraoperative positioning and maintained with posterior lateral mass fixation and fusion.

当不伴有颈椎不稳的颈椎病并颈髓中心管损伤患者需要手术治疗时，整个颈椎的序列和受累的节段决定了手术入路的选择。颈椎处于前凸状态，尤其是多节段颈髓均有受压时，建议采用后方入路进行全椎板切除融合或颈椎椎板成形术。假如颈椎处于中立位或稍微后凸时，有时通过后方的全椎板切除，术中复位和侧块螺钉固定融合，可以恢复颈椎的前凸。

The split between the two groups can hardly be papered over.
