棘齿

The X line that the method collects 75 patients is smooth piece reach CT piece, observe cervical vertebra thorn respectively dash forward, horizontal dash forward even the line, extensive region - tine joint clearance, dentate dash forward with spine dash forward the change of bisector.

方法收集75名患者的X线平片及CT片，分别观察颈椎棘突、横突的连线，寰-齿关节间隙，齿状突和棘突平分线的变化。

Results: 13 cases with 19 bone broken points,the positions are at dens ,side plank of atlas,occipital,plank of axis,processus spinosus etc.23 cases with axis and atlas half dislocation.Of which,16 cases were with pure dislocation,7 cases with rotating dislocation,11 cases were with swollen at the side of vertebra,2 cases with depressing of vertebral artery,5 cases with continued narrowing of vertebral canal.

结果：13例共见19处骨折，部位分别为齿状突、寰椎侧块、枕骨、枢椎椎板、棘突等，寰枢关节脱位23例，其中单纯性脱位16例，旋转性半脱位7例，11例合并椎旁血肿，2例见椎动脉受压，5例继发性椎管狭窄。

The front suture width of axis and atlas joints and the shift degree of dens were also measured.results: 13 cases with 19 bone broken points,the positions are at dens ,side plank of atlas,occipital,plank of axis,processus spinosus etc.23 cases with axis and atlas half dislocation.of which,16 cases were with pure dislocation,7 cases with rotating dislocation,11 cases were with swollen at the side of vertebra,2 cases with depressing of vertebral artery,5 cases with continued narrowing of vertebral canal.conclusions: ct has the advantage of quickness,safety and high density discerning,it can reveal details of acute axis and atlas damages,so it has great importance to treatment scheme making and to the prognosticate.

结果：13例共见19处骨折，部位分别为齿状突、寰椎侧块、枕骨、枢椎椎板、棘突等，寰枢关节脱位23例，其中单纯性脱位16例，旋转性半脱位7例，11例合并椎旁血肿，2例见椎动脉受压，5例继发性椎管狭窄。结论：ct具有快捷、安全、密度分辨率高等优点，可明确急性寰枢关节损伤细节，对制定治疗方案及估价预后具有重要作用。

A new-type bike features that its pedal crank has an arc rack bar acting on the ratchet gear in single direction and in turn driving the drive chain wheel, a reset unit composed of crank mechanism is used to make left and right pedal cranks be pedaled alternatively, and its front movable saddle plate is connected via connecting rod to pedal crank for making rider comfortable. Its advantages are high drive performance and efficiency and saving labour.

一种新式自行车，其最大特点是蹬踏杆上含有一弧形齿条，由该弧形齿条上的轮齿作用于具有单向离合的棘齿轮，从而带动主动链轮转动，由曲柄机构组成的复位器使左右蹬踏杆能够交替连续踩踏以驱动自行车行驶，前活动座板与蹬踏杆由连杆相连结，从而实现同步摆动给以乘骑者踩踏感到舒适，该发明具有传动性能好，效率高，力损耗小等优点。
