颈椎

Objective. The proximity of the plate to the adjacent disc space appeared to be the critical determinant of adjacent level ossication development but we had no data on unplated arthrodesis.

目的：在邻近节段骨化的病例中，板的近端和邻近椎间盘的位置似乎是很重要的决定性因素，但是我们没有相应的未使用板的颈椎融合的资料。

Summary of Background Data. VAI is a rare complication of cervical spine surgery, but it may be catastrophic.

背景资料：虽然VAI是颈椎手术的一种比较罕见的并发症，但其后果及其严重。

The incidence of VAI during cervical spine surgery from this survey was similar to or slightly less than that in the literature.

这项调查所得出的颈椎手术时椎动脉损伤的发生率，相似或略小于其它文献。

Methods. A questionnaire was sent to our affiliated hospitals requesting information regarding iatrogenic VAI during cervical spine surgery.

向我们的各附属医院分发调查问卷，以获得关于颈椎手术术中医源性VAI的资料。

Objective To research the feasibility of porous hydroxylaptite bioceramic as a kind of bone grafting substitute in the cervical subtotal vertebrectomy.

目的 研究多孔羟基磷灰石生物陶瓷作为植骨替代材料在颈椎椎体次全切除术中的可行性。

When the spine is focally kyphotic, particularly when there is a fixed kyphosis, or in the presence of anterior compression from a disc protrusion or spondylotic bar at 1 or 2 segments, an anterior surgical decompression (vertebrectomy or multiple discectomies) is indicated.19 Fusion and stabilization by means of an anterior strut and plate is also supported.27

当颈椎处于明显的后凸，尤其是僵硬性后凸，或者颈髓压迫来自前方的1到2个节段的突出椎间盘或椎间关节时，经过前方入路进行减压（椎体切除或多节段椎间盘切除）是合适的。融合固定的方法包括前方支撑和钉板系统固定。

Phase-contrast MRI is a reliable technique to evaluate hemodynamics of vertebroarterial flow and to determine vertebroarterial stenosis accurately.

MR相位速度图是评价椎动脉血流动力学变化的可靠技术，能对椎动脉型颈椎0的诊断提供准确依据。

Fifty-six rabbits were injected with 775 injection in the left side of cervical vertebrae to make animal model of chronic vertebroarterial cervical spondylopathy.

提要 采用家兔58只，于颈椎左侧注射组织硬化剂775注射液，制成慢性椎动脉型颈椎病动物模型。

Symptom disappearance: pain was 0 grade; the cervical vertebral physiological curvature restored by 10°- 15° and rheoencephalogram showed that the contraction peak velocity of the vertebroarterial blood supply became normal.

明显好转：疼痛降低2级以上；颈椎的生理弯曲恢复6°～9°；脑血流图椎动脉收缩峰速度恢复正常范围的80％。

Improvement: the pain reduced by 1 grade, the cervical vertebral physiological curvature restored by 3°- 5° and rheoencephalogram showed that the vertebroarterial blood supply restored to 40％- 80％ of the normal range.

无效：疼痛无变化；颈椎的生理弯曲恢复3°以下；脑血流图椎动脉收缩峰速度在正常范围的40％以下。

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.
