In sagittal plane,the PPSI of each level moved from inferoposterior to superoanterior with an arc trajectory.The PPSI displacements and angular variation increased from L1 to L4,however,these two decreased in L5 simultaneously.The rotation radius had no relationship with lumbar segment.Flexion-extension ROM from L1/2 to L5/S1 increased gradually.

各腰椎屈伸运动时PPSI矢状位上呈由后下至前上的弧线轨迹，L1~L4其位移量和倾斜角度逐渐增大，L5两值同时减小；其旋转半径与腰椎序列无明确关系。L1/2至L5/S1屈伸活动度逐渐增加。

In this study, we comparedelectrical nerve stimulation and ultrasound guidance for thelateral sagittal infraclavicular block.

这次研究中，我们比较电神经刺激和超声引导用於侧位矢状面的锁骨下阻滞。

We conclude that favorable results can be obtainedwhen either nerve stimulation or ultrasound guidance is usedfor lateral sagittal infraclavicular block.

我们得出的结论是无论是用神经刺激还是超声引导来进行侧位矢状面的锁骨下阻滞都能取得良好的结果。

Methods In all the 7 cases we employed traditional osteotomies, bone resection and bone graft fixation through coronary and nasofrontal incisions to reduce their interorbital distance.

所有7例患者均采用传统颅内外联合径路手术，通过双侧头皮冠状切口和鼻正中部眉间矢状切口行眶周截骨，眶内移和骨块固定，缩小内眶距。

As a result, it is now possible to characterize the segmental and intersegmental, sagittal plane motion response of the lumbar spine.

因此，现在可以表征段和段间，腰椎矢状面的运动响应。

Results: The thickness of intertransverse ligament was about 0.60~1.39mm.

结果：横突间韧带厚度0.60~1.39mm；L(下标 3-5)节段动脉前支及伴行静脉90%以上位于相邻横突间韧带腹侧上1/2处，横突间韧带背侧中1/3处有一恒定节段动脉分支；腰神经前支与矢状面夹角18.90°~39.20°，下位横突的副突处距前方走行腰神经前支距离为5.63~8.05mm，椎弓峡部侧缘至腰神经前支的距离为1.73~3.64mm。

Preoperative sagittal CT scan reconstruction demonstrates the intravertebral vacuum, as well as intradiskal gas.

术前CT矢状位扫描重建示椎体内真空，在椎间盘内也可见气体。

Coronal and sagittal CT reconstructions demonstrate the intravertebral vacuum.

冠状位及矢状位的CT重建示椎体内真空。

Results Sagittal MRI revealed horizontal intravertebral area, hypointense on T1-weighted images and hyperintense with surrounding band of hypointensity on T2-weighted images.

结果 矢状位MRI显示水平方向的带状区， T1加权像为低信号， T2加权像为高信号，周围有低信号区包绕。

The incidence of junctional kyphosis and its association to the above parameters and to fusion levels were assessed.

在集中式数据库内采用不同的影像学指标测量脊柱后凸、前凸，C4矢状面中垂线，顶椎横移距，交界处曲度和骨盆倾角；计算交界后凸的发生率以及与上述指标的相关性、融合水平；评估采用联合前后路手术和单纯后路后术患者并发症发生率及其差别。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
