查询词典 lordotic

Objective: To establish the optimal height of the strut-graft for clinical surgery, this study analyzed the effect of change in strut-graft height on the lordotic curvatures and immediate biomechanical stability of the cervical spine on which corpectomy and strut-graft reconstruction with different height was performed.

Flexion overload, unbalanced shear forces, forced rotation, alternating forward and backward bending of the lower spine, and high compression in lordotic posture were proposed, among others, as the major mechanical agents.

低位脊柱超负荷的力学因素包括屈曲负荷，不平衡的剪切力，旋转，交替的前后弯曲和维持前曲姿势等。

ResultsAlmost all the cases obtained a good clinical effect after the operation. The symptoms and signs were both relieved. Lumbar lordotic angle and intervertebral space height on radiology were restored obviously. Spinal fusion rate achieved 96.4% after the follow-up.

结果几乎所有患者手术后原症状和体征均得到缓解，影像学上的腰椎前凸角、椎间隙高度指数都有明显恢复，手术后6~26个月，脊柱融合率达到96.4%。

Strut-graft with an appropriate distraction after corpectomy plays an important role not only in regain and maintain the cervical spine lordotic curvatures but also in acquire the global immediate stability of the cervical spine. After single vertebra corpectomy, the proper range of distraction between the superior and inferior vertebra maybe among 4-6 millimeters.

中下颈椎单椎体次全切除减压后，适当高度的撑开植骨对恢复和维持颈椎曲度以及手术节段的即刻稳定性有重要作用，中下颈椎单椎体次全切除减压后支撑植骨的高度应该是在手术椎体的上位和下位椎体间高度的基础上再撑开4～6mm左右。

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 mean preoperative kyphotic angle for the 11 individuals with the thoracic or thoracolumbar burst fractures was 24.6° and the mean preoperative lordotic angle for the 3 individuals with lumbar burst fractures was 10.6°.

平均出血596.4 mL。关于术后并发症，出现一过性神经损伤加重病人1例，假关节形成1例。

Lateral roentgenograms of the lumbar spine and the hip joint were obtained in the upright position to determine pelvic inclination, sacral slope angle, lumbar lordotic angle (L1-L5), disc angle of L5/S1, and pelvic angle (by Jackson's method).

所有病例都拍摄了竖立位腰椎和髋关节侧位片，从而确定他们的骨盆倾斜度、骶骨倾斜角、腰椎前凸角（L1－L5）、L5/S1椎间盘成角和盆腔角。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
