To evaluate the method and curative effect of posterior internal fixation and bone grafting fusion for atlantoaxial fracture or dislocation.

［目的］探讨寰枢椎骨折脱位后路内固定植骨融合术的方法和疗效。

For simulating the displacement and rotation of the vertebrae which nail has been implanted on,reconstructing a 3-D model of patient's spine is first step in virtual spinal diorthosis surgery.

在计算机虚拟脊椎矫正系统中，为模拟钢钉打入椎骨后相关脊椎骨产生位移和旋转，需要建立患者脊柱的三维模型。

Objective: To study the expression of TNF-α and TGF-β1 in vertebrae of model rats of epimedium preventing ovariectomy-induced osteoporosis.

目的：研究TNF-α、TGF-β1在灌服淫羊藿水提液的去势大鼠椎骨中的表达，探讨淫羊藿防治绝经后骨质疏松症的机理。

More shoving and rotating, and it's quickly apparentthat the skull must traverse a passage that seems smaller than itself,cramped not only by the ischial bones but also by the coccyx, thebottom of the tailbone, which pokes into the lower pelvic cavity.

多加推挤和旋转后，这样一个事实就非常明显：头骨必须穿过看似比它自己还要小的通道，堵塞不仅仅来自于坐骨骨头，还有尾骨，尾椎骨底部，这些都指向较低的盆腔。

Methods Four lumbosacral spinal specimens of human were used to manufacture the intact segmental specimen, then the specimen models were worked out by cutting the isthmic of intact specimens with wire-saw, and then one pure bone-towel or one anterior fusing cage was inserted separately into the model's interbody space to stable the model. Finally, all of the specimens' stiffness of the upper four conditions was measured.

使用4具人尸腰骶椎骨制成空白运动节段标本，用线锯锯断椎弓峡部法制成峡部裂模型标本，再分别用单纯骨块、AFC置入模型标本椎间隙以固定该节段，测试以上4种状态下节段标本的应变、位移、刚度。

Thoracolumbar kyphoscoliosis occurred in only 1 patient because of a posterolateral quadrant ertebra.

因后外象限的椎骨引起的胸腰椎后侧凸仅见于1个病人。

Optical Localizer have the very high accuracy and reliability, but very expensive.

传感器独立地测量定位椎骨体和钻头，然后计算出它们的相对位置和方位。

The association between the multidirectional instabilities and the vertebral injuries to each of load-sharing point score was analyzed.

针对每个载荷分担点评分的椎骨损伤与多向不稳定性之间的相关性被予以分析。

The association between the multidirectional instabilities and the ertebral injuries to each of load-sharing point score was analyzed.

针对每个载荷分担点评分的椎骨损伤与多向不稳定性之间的相关性被予以分析。

METHODS: The stability of intact specimens in flexion, extension, lateral bending and torsion was examined. A fracture model was created using dropping technique. The fracture model was instrumented with short-segment pedicular screw fixation (4-screw construct) or the intermediate screws structure (6-screw construct).

测量完整标本前屈-后伸、侧屈及旋转的稳定性后，通过重物撞击技术制造伤椎骨折模型，然后对每个标本行传统短节段椎弓根螺钉固定（4枚螺钉固定）及增加骨折椎椎弓根螺钉固定（6螺钉固定）。

Do not gum up the work by telling mother what we are going to do .

别告诉母亲我们要干的事，那会把事情搞糟的。

In recent years, application of the partial prestressed concrete beam s is developed.

近年来，随着部分预应力砼梁应用的推广，发现我国规范所采用的名义拉应力法的计算结果不稳定。
