颈椎

For sustaining the stability of the cervical vertebra, Halo-vest is the main therapy equipment of epistropheus fracture. However, the risks of pin-site infection and the bulky appearance of Halo-vest may lessen patients' comfort and affect their psychological well-being.

第二颈椎骨折之治疗，通常使用颈椎外固定器以维持颈椎稳定性，但颅钉部位之潜在感染风险，其笨重的外观可能影响个案造成舒适情况改变及心理问题。

Retaining LMC of cervical posterior spinous process has important clinical significance for maintaining cervical lordosis and its stability as well as reducing the incidence of postoperative axial symptoms.

保留颈椎后部棘突肌肉韧带复合体对于其发挥维持颈椎生理曲度和颈椎的稳定性、减少术后轴性症状的发生等具有重要的临床意义。

Methods 14 patients with cervical spinal unstableness were treated with transpedical screw fixation with a specific technique to place the screw.

运用个体化综合置钉法行颈椎弓根固定治疗颈椎不稳 14例，其中陈旧性寰枢椎不稳 7例，颈椎管狭窄 1例，骨折脱位 6例。

AIM: The recovery of cervical alignment is significant for the long-term stability and biomechanics of cervical vertebra.

目的：恢复颈椎的生理曲度对维持颈椎的远期稳定性及恢复颈椎本身的生物力学环境有重要意义。

1.Two level artificial cervical disc replacement can maintain stress in the caudad (C5/6,C6/7) zygapophyseal joint, thus reconstruct biomechanical property of cervical spine.

颈椎双节段人工椎间盘置换后置换下位节段和邻近下位节段关节突关节内压力与完整标本相近，提示颈椎双节段人工椎间盘置换能够重建颈椎生物力学性能。2。

The cervical vertebra good recovery instrument is a medical instrument used for pulling,fixing and massaging the nape,It can prevent and treat various kinds of cervical vertebra diseases such as bone hyperplasia,fracture misplacement coxal projecting of the cervical vertebra.

&颈椎康复器&是一种用于颈部的牵引、外固定、按摩的医疗器械，适用于防治颈椎病、颈椎骨质增生、颈椎错位、颈椎间盘突出；还适用于因基底动脉不足引起的颈性头晕、晕厥等症状的治疗。

Even though the range of motion was larger for the normal group than for the ACDF group, the intersegmental rotations at the adjacent C6-C7 and C4-C5 levels in the ACDF group were 13.4 and 8.8 compared with 3.7 and 4.8 in the normal group, respectively, during the neck motion from 20 flexion to 15 extension.

结果：纵使正常组的活动范围比颈椎前路减压和融合活动范围要大，后者的颈椎6-7和颈椎4-5椎间的旋转在颈部20度屈曲时为13.4度和在颈部15度伸直时8.8度，相比正常组的颈椎6-7和颈椎4-5椎间的旋转在颈部20度屈曲时为3.7度和在颈部15度伸直时4.8度。

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。

Abstract］ objective to explore the accuracy and safety of safety drillprepared for cervical pedicle screw trajectory.methods fourteen adult cadaver specimens of cervical spine（c3～c7）with intact structures including ligaments and perivertebral muscles were reserved and used.according to the radiographic measurements,safety drill was inserted into cervical pedicle individually.the evaluation of the drill's trajectory was carried out by ct scan and three-dimension reconstruction and autopsy.results one hundred and forty drill's trajectories were made.9 holes failed with a perforation rate of 6.4%.conclusion the safety drill prepared for cervical pedicle screw hole is safe and effective and can be applied and popularized clinically.

目的 探索安全钻头应用于颈椎弓根螺钉孔道钻探的安全性与准确性。方法随机取14具福尔马林浸泡的成人颈椎标本（c3～c7），保留完整的脊柱三柱结构及相关的韧带和椎旁肌，根据影像学测量的进钉点和进钉方向，模拟颈椎后路手术过程。选用安全钻头，进行实际的颈椎弓根螺钉孔道的钻探，将孔道行ct扫描，并斜位三维重建孔道形态，并以肉眼直视观察结果为金标准，评价孔道钻探的成败。结果钻探孔道准确率89.3%（125/140），穿孔率6.4%（9/140）。结论安全钻头应用于颈椎弓根螺钉孔道钻探的安全性与准确性均较高，可以在临床上推广使用。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
