颈椎

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。

Of them, 25 patients received one-level disk replacement, and 8 received two-level disk replacement.

单节段颈椎人工间盘置换25例，双节段颈椎人工间盘置换8例。随访时年龄35~73岁。

During both techniques, motionwas mainly an extension concentrated in the rostral C-spineand occurred predominantly during glottic visualization.

两种插管技术对颈椎产生的移动主要都是使颈椎前端伸展，且主要发生在显露声门时。

We also observed and measured the distance and section of some muscles such as long muscle of neck、long muscle of head、sternocleidomastoid、trapezius、longissimus、inultifidus、splenius、semispinal muscle of head、semispinal muscle of neck、anterior scalene、middle scalene 、posterior scalene et al. We achieved the moment of force and downloaded the force in the model .We also added gravity of head.

通过横截面积肌力计算法，测量尸体颈椎周围的主要肌肉：胸锁乳突肌、斜方肌、头长肌、颈长肌、肩胛提肌、夹肌、前斜角肌、中斜角肌、后斜角肌、多裂肌等的横截面积及其与颈椎纵轴的中心距数值，求得力矩值，直接或根据力矩等价公式间接的将肌力值加载于模型体表各点。

Methods(1)The largest force of thumb to against the spinous process of the fourth cervical vertebra was tested and recorded with a pressure sensor testing system.

(1)对46名受试者进行颈椎坐位旋转手法操作，应用压力传感器检测系统，检测并记录出现咔哒声响时术者拇指顶推受试者第四颈椎棘突的最大推扳力。

Results After anterior cervical decompression with trepan and fusion of BAK implantation,the Cobb's angles were smaller than pre operation and there were no difference in the cervical lordotic angles,intervertebral space heights.

结果 颈椎前路环锯减压BAK融合器植入融合后Cobb角较术前变小，而椎间高度和颈椎前弯度手术前后无显著性差异，随访期间则三者均无显著性差异。

Objective To study the thin slices and MRI cross?sectional anatomy of the cervical vertebral uncinate process and its adjacent tissues, to provide basic anatomic data for cervical retrograde syndrome.

目的 阐明颈椎钩突在薄层断面和MRI断面图像上与周围结构的毗邻关系，为颈椎退行性疾病提供影像学诊断依据。

The distance between the uncinate process and the medial side of the vertebral artery, the distance between the uncinate process and the cervical nerve were measured.

结果 CVH数据集的薄层断面清晰显示颈椎钩突及其周围结构，在断面上测量并得出钩突与颈神经、钩突与椎动脉的距离的平均值，MRI清楚显示颈椎钩突及其邻近结构。

Results The cross?sectional images of the CVH and MRI images fairly could display the uncinate process and it's adjacent structures. The distance between the uncinate process and the medial side of the vertebral artery, the distance between the uncinate process and the cervical nerve were measured.

结果 CVH数据集的薄层断面清晰显示颈椎钩突及其周围结构，在断面上测量并得出钩突与颈神经、钩突与椎动脉的距离的平均值，MRI清楚显示颈椎钩突及其邻近结构。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
