Conclusion the superior lateral quadrant was the safe area of the cervical lateral mass screw. The safe exit point was the juncture between the transverse process and the facet.
结论颈椎侧块外上象限是螺钉植入的安全区，横突与关节突相交处是安全的出钉点。
Summary of Background Data. During C1 lateral mass screw insertion and in posterior C1-C2 fixation, iatrogenic injury of C1-C2 venous sinus results in bleeding, which is troublesome.
在后路寰枢椎内固定术时C1侧块钉置入不当引起的C1 -C2静脉窦医源性损伤所致的术中出血处理起来较棘手。
The response surface methodology was used to study the influences of screw speed, barrel temperature, material moisture and enzyme mass fraction on DE values.
采用响应面分析方法研究了螺杆转速、机筒温度、物料水分和酶质量分数对挤出物de值的影响规律。
Result the parameters of posterior arch, lateral mass, vertebral artery groove, axis length of screw pass via posterior arch and lateral mass, projection and direction of screw were measured.
结果测量出寰椎后弓、侧块、椎动脉沟、后弓侧块螺钉通道的轴线长度，及后弓进钉点和进钉方向等参数。
Objective: To provide anatomical data for anterior approach screw fixation through C2 vertebral body to C1 lateral mass.
目的：为临床上行前路经枢椎体至寰椎侧块螺钉内固定提供实验依据。
The result showed that DE values were not effected by screw speed, but increased with material moisture, enzyme mass fraction and barrel temperature;
结果表明：淀粉酶转化程度不受螺杆转速影响，但随物料水分、酶质量分数和机筒温度增加而增大；
Attached is the photo showing the cover piece which is fastening onto the head band by yellow glue which is much better than reverse the screw fastening in mass production.
附件是封面示图。 我们会在页眉处涂上黄色胶把封面粘住，这比批量生产中采取的“反旋螺钉”固定法要好得多。
Posterior screw fixation on atlas includes posterior screw fixation within lateral mass of atlas and in atlas via posterior arch and lateral mass.
后路寰椎螺钉固定包括寰椎侧块螺钉和寰椎后弓侧块螺钉固定。
