膝关节

By the developed optical system with localizers of high resolution and indicators of high speed, the presented navigation system offers useful computer-aided TKR surgery tool with simple processes and high operation quality.

作为展望，本文在最后对膝关节置换手术导航的进一步研究提出了两点可行的方案和设想，包括嵌入式光学定位系统设计方案以及远程外科手术的设想。

Legs and feet close together, the legs have only four points of contact, that is, mid-thigh, knee, calf and heel.

双腿并拢时，两腿间只有四点接触，即大腿中部、膝关节、小腿肚和脚跟。

In those waxworks in Henry street I myself saw some Aztecs, as they are called, sitting bowlegged, they couldn't straighten their legs if you paid them because the muscles here, you see, he proceeded, indicating on his companion the brief outline of the sinews or whatever you like to call them behind the right knee, were utterly powerless from sitting that way so long cramped up, being adored as gods.

他们蜷着腿坐在那儿。你即便给他们钱，他们也伸不直腿，因为这儿的腱--你瞧，&他为伙伴简单地比划了一下，&或者你随便怎么叫吧，反正是在右膝关节后边--完全不灵啦。这都是被当作神来崇拜，长年那样蜷腿坐着造成的。

Methods: rabbit bone marrow mesenchymal stem cells were purified, and then cultured in inducing medium containing transforming growth factor-β1; mtt assay was employed to evaluate the proliferative activity of induced cells; immunohistochemical assay was used to detect the expression of type ⅱ collagen; induced cells were transplanted into the knee of rabbit, and x-ray photography was employed to observe the repair and formation of cartilage.

纯化兔骨髓间充质干细胞；用含转化生长因子β1的诱导液培养骨髓间充质干细胞；以mtt测定诱导细胞的增殖活性；免疫组化检测ⅱ型胶原蛋白的表达；诱导后的细胞移植于白兔膝关节内，x线摄片观察软骨修复形成情况。

METHODS: Sixty patients undergoing elective unilateral TKAunder spinal anesthesia received in a randomized, double-blindmanner a femoral, obturator, or sham nerve block at the endof surgery.

60名在脊麻下择期行单侧膝关节成形术的患者，在手术结束后接受随机双盲的股神经阻滞或闭孔神经阻滞或未作神经阻滞的临床研究。

The femur, tibia and knee joint were reconstructed after redacting and analyzing the data by 3 D software.

通过软件对数据进行编辑、分析，重建股骨、胫骨及膝关节的三维立体模型。

Methods:(1) bFGF was loaded with PLGA, PELA and gelatin microspheres. The pharmac characteristics of particle size distribution, loading efficiency, entrapment efficiency, bFGF release kinetics were evaluated with scanning electronic microscope, MTT and ELISA respectively.

目的：制备bFGF缓释微球并作处方筛选，在体外培养的软骨细胞中观察其促有丝分裂作用和促基质合成作用，以及在兔膝关节全层软骨缺损模型中验证其促进软骨修复的作用，为其临床应用提供实验基础。

Objective: To investigate the effect of improved ankle-foot orthotics on knee joint movement.

目的：研究改良式踝足矫形器对膝关节运动角度的影响。

Results: Among 17 cases of GCTTS, 3 cases were located in knee joint,6 in ankle joint,2 in wrist joint,3 in hand and 3 in foot.11 cases were the diffuse form,6 were focal.

结果：腱鞘巨细胞瘤位于膝关节3例，踝关节6例，腕关节2例，3例手部，3例足部。

Legs - Well-boned, muscular, and straight when viewed from rear with well-bent stifles, not close set but in line with forequarters.

从后面观查，腿直。膝关节适当弯曲，两腿不紧贴，但与前肢成一线。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
