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。

It mainly concentrates on the trainee's coax outside open to fix the foot position tortured by benting the knees joint to be lower to-145 degree.

The amplitude of hamstrings and gastrocnemius were more related with pelvic support. During dynamic support modes, even the load was low the muscle activation was still higher than that in SE mode. It appeared biarticular muscles recruit more during dynamic pelvic support mode, and also showed the ability to adjust under the task demands.

而大腿后肌群、腓肠肌的活化量则与骨盆支撑模式较为相关，在活动座椅脚踏车活动的肌肉活化量较大，显示在活动式骨盆支撑的脚踏车运动中，双关节肌肉有较多的肌肉徵召；亦显现出双关节肌肉因应任务不同时的微调功能。

Objective To compare the effects of hip arthroplasty and AO compressive cannular in treatment of the displaced fracture of femoral neck in elderly.Methods From 1995.5 to 2004.11, 78 elderly patients of over 65 years old with displaced femoral neck fracture were operated with hip arthroplasty and AO compressive cannular.

目的 比较人工关节置换术与AO加压空心螺钉术治疗老年人有移位股骨颈骨折的疗效方法将1995年5月～2004年11月我院收治的78例年龄在65周岁以上的有移位的新鲜股骨颈骨折患者进行回顾性研究，将病例分 A、B两组，A组为人工关节置换组，B组为AO加压空心螺钉治疗组。

The central technique is preferred because a capsulectomy is not required; however, because this technique is performed under traction, the tissue is under tension and the degree of plication is limited.

因为关节囊切开不是必须的，故在中心技术是优先的；然而在牵引下操作这项技术，局部的组织在紧张状态下关节囊切开的程度受到限制。

After one-month follow-up the MWM patients also had a significantly better improvement in external rotation, p﹤0.05. MWM was proved to be at least equally effective in the treatment of adhesive capsulitis compared to EMTs.

此外在二维重复测量的多变项分析（2-way ANOVA with repeated measures）的结果显示在一个月的追踪时，动态关节松动术治疗的患者在外转上有显著较活动极限下做关节松动术组为佳的改善，p﹤0.05。

During the operation, two tracts of tendons soaked in gentamicin saline for 15 minutes were conduplicated, and one end of the tendon was cancellous bone screw and fixed to the tibia attachment point of posterior cruciate ligament, and the other end was introduced into the joint through retention suture.

术中将用庆大霉素盐水浸泡过15min的两束异体肌腱对折，肌腱的一端套入松质骨螺钉加垫片固定在后叉韧带的胫骨附着点处，另一端通过牵引线引入关节内，修复切开的后关节囊。

Methods: 28 patients with isolated patellofemoral complications after total knee arthroplasty were scaned by computed tomography. The epicondylar axis and tibial tubercle were used as references to measure rotational alignment of the femoral and tibial components.

28例施行人工全膝关节置换术后出现单纯髌股关节并发症的患者进行膝关节轴位CT扫描，选择股骨髁上轴和胫骨结节作为CT扫描的参考标志来测量股骨假体和胫骨假体的旋转角度，分析旋转稳定性与髌股关节并发症的相关性。

The purpose of this study was to examine the prealence of isolated complete capsular tears and to assess the clinical features as well as the results of surgical treatment of recurrent anterior glenohumeral instability caused by such tears.

本研究的目的是考察单独的关节囊全层撕裂的患病率，评价其临床特征以及外科治疗由这种撕裂造成的复发性盂肱关节前部方不稳定的疗效。

The results were expressed in mean±1SD. Pearson X~2 test and One-way ANOVA test were used. The data analyzed using the SPSS (version 11.5). Results: The sensitivity, specificity, positive and negative value of US for the LPEH model on the children cadaver were 88%, 84%, 79%, 91%, respectively. With regard to the thickness of femora head cartilage, the thickness of the anterior layer or posterior layer, there were no significant differences among three groups. However, the anterior layer was thicker than the posterior layer in three groups. The fluid in hip joint was detected in all of 21 symptomatic hips, which was clear commonly (90%) in early procedure. The amount of fluid in anterior recess showed a positive correlation with age (p .05). No fluid was detected in the asymptomatic and normal hips (2mm). The mean maximum width of inferomedial recess was significantly larger than that of anterior recess (12.50±4.04mm vs.4.35±0.8mm, p 0.05) in the symptomatic hip joints. The echogenic entrapped labral plicaes were demonstrated in the inferomedial recess in all of 21 children with LPEH, whose length and width ranged from 5.3mm-25.0mm (mean,15.6±5.6mm) and from 4.0mm-17.0mm (mean,8.9±7.8mm).

结果1，尸体LPEH髋关节模型的超声诊断敏感性、特异性分别为88％、84％，阳性预测值、阴性预测值分别为79％、91％。2，21例患儿的LPEH患髋(21侧)、健髋(21侧)，以及21例正常儿童健髋(42侧)的超声检查显示：髋关节周围软组织及股骨头无形态结构差别；股骨头软骨厚度无统计学差异(3.5±0.5mm vs.3.6±0.4mm vs.3.6±0.5mm，p＞0.05)；关节囊前层及后层厚度无统计学差异(前层厚度2.79±0.74 mm vs.2.56±0.40mm vs.2.56±0.72mm；后层厚度2.70±0.82mm vs.2.48±0.54mm vs.2.44±0.58mm，p＞0.05)，但LPEH患髋关节囊前、后层均较后二组有增厚趋势。3，LPEH患髋均存在关节腔内积液，且早期较为清晰；积液以髋关节内下间隙明显，内下间隙较前间隙明显增宽(12.50±4.04mm vs.4.35±0.8mm，p＜0.05)，其内见嵌顿滑膜唇皱襞呈稍强回声的占位性团块，长约15.6±5.6mm，宽约8.9±7.8mm，90.5％(19／21)嵌顿皱襞内未见血流信号。4，所有LPEH患髋治疗后超声复诊均显示正常。
