踝关节

Ankle injuries are one of the most common injuries in orthopaedics clinic. They result in repeated injuries by ankle instability and anchylosis etc.

踝关节扭伤是骨科临床常见病，易造成踝关节不稳而出现反复扭伤和关节活动度障碍等后遗症。

Based on the analysis of the structure and motion mode of anklebone, a 3-RSS/S parallel robot was proposed for anklebone rehabilitation exercises in this paper.

在分析踝关节结构及运动方式的基础上，提出了一种3-RSS/S并联机器人方案用于踝关节康复治疗，并对其进行了位置逆解分析，得出了雅可比矩阵，为该机构的进一步分析、研发奠定了理论基础。

It's very significant to analysis the cause of anklebone wound, basically to bring forward the feasible prevention and cure measure that is good for people to exercise their anklebone and enhance the flexility of the joint, as well as reduce wounds while doing sports possibly.

分析踝关节损伤的原因，并在此基础上提出可行的预防和治疗措施，对人们平时锻炼踝关节，提高关节的柔韧性，尽可能地减少运动损伤有重要意义。

The technology of quasi coronary scan can display the exact location,type,degree of graveness and dislocation of the fracture anklebone,and improve the rate of diagonosis of the anklebone.

踝关节准冠状位CT扫描技术能从近似冠状位角度显示踝关节骨折的具体部位、类型、严重程度及移位情况，能提高踝关节骨折的检出率。

Of these all but one, which had normal ligament, proved to correspond to the operative finding As there was only one false positive finding among our surgical cases with both the "definite" and "suspectable" positive arthrograms, we concluded that ankle arthrogaraphy is relatively reliable and may be worth doing even in chronic cases if only for reference.

由於在我们手术的患者当中若把上述「明确」的和「疑似」的踝关节摄影发现一并考量，则只有一例在手术中发现是错误的，故我们认为踝关节摄影即使在慢性踝关节不隐的患者仍有相当的可信度，并且值得做为参考。

Two component design total ankle replacement is based on restricted type design to prevent dislocation ,and make syndesmosis union to enlarge tibia component contact area and stability. Three component design total ankle replacement is based on unrestricted type design. Components are mimic to anatomic shape ,and congruent polyethylene insert was also characterized. Successful total ankle replacement depends on reasonable prosthesis design and rational contact stress .

二件式人工踝关节，其设计理念，在於以高限制型设计，避免脱位之产生，并以胫骨腓骨骨联合扩大胫骨元件的接触面积与稳定度；三件式人工踝关节，主张以非限制型设计，近於解剖形状之元件，以及与关节面一致构形的聚乙烯内衬为其特点成功的全踝人工关节置换术仰赖合理的踝关节设计以及合理的接触压力。

Besides, contact stress in tibia component-polyethylene insert interface of three component design arise 31% to 34% only in dorsiflexion 40 degree and plantar flexion 40 degree due to flat smooth surface design.

二件式人工踝关节的接触压力平均为7.8 MPa，三件式人工踝关节胫骨元件-关节内衬接触面的接触压力平均为4.4 MPa最小；三件式人工踝关节关节内衬-距骨元件接触面的接触压力平均为5.7 MPa居中。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
