However, survival came at a steep price with the debilitation of my family's financial foundation with medical expenses.

1989年，我父亲意外的决定去追寻他的梦想，这对他的家庭而言是极为不切实际的，他决定脱离在台湾学院所学的观光事业专业而从事一个彻底不同和看起来较不顺利的路途，投入陶瓷学习两年半後在1992年，在中国他发生了重大车祸，外科太夫当时曾表示90%他将不能恢复行走是因整个股骨全部碎裂，舆痛苦博击的他历经了大的手术，医生们置换了所有的股骨，术後他表现极乐观及强壮，慢慢的走向复原。

Objective:To evaluate the clinical effect of different internal fixation devices commonly used for distal femoral fractures.

Femoral stress has been studied by electrometric experimental stress analysis methods to know about femoral stress value and its distribution case in front and rear of replacement to artificial femoral head.

结果表明：股骨内外侧应力大于前后侧应力；人工股骨头置换术后股骨头近端应力明显下降；在使用骨水泥固定后，股骨上各点应力无大的变化，而当使用带颈领的人工股骨头时，股骨头近端应力下降受到抑制。

Material and MethodsRA Rabbit Model group: 15 early RA rabbits of the same weight and variety Control group:10 normal rabbits of the same weight and varietyMethods of making RA rabbit model:elect 15 normal rabbits of the same weight and variety, dissolve Ovalbumin in 0.9% sodium chloride solution, to make the solution of 20mg/ml concengtration, blend the same quantity of complete Freund′s Adjuvant equably ,inject the mixed solution into endermic tissue of the rabbit′s scapular section, making the rabbits allergic, inject 1 ml of the mixed solution to one rabbit every time, inject 1 ml of the mixed solution in 5 different places of the rabbit′s scapular section, inject the rabbit one time every week,inject 3 weeks continuously,it turned out to be that the rabbits will be allergic, inject Ovalbumin blent with the 0.9% sodium chloride solution into the knee joint cavity of the rabbits in the fourth week, 5 mg Ovalbumin every knee joint cavity,two knees of every rabbit of the 15 rabbits are both injected,the arthrosis diameter and the exterior temperature of the knees will be added obviously in 24 hours,and they will drop gradually,at the time of the 14th or 21th day, the arthrosis diameter and the exterior temperature of the knees will get to the balance time,the incidence rate of RA is 100%.after the RA model succeeds,it is the early time of RA from the first week to the fourth week,after the fourth week,it is the late time of RA, the cartilage of the femoral condyle and the subchondral bone cortices will be changed unrecoverily.

资料与方法RA模型组：早期RA家兔模型15只，品种及体重接近。对照组：正常家兔10只，品种及体重接近。RA家兔模型制作方法：选取15只成年家兔，体重、品种接近，将卵蛋白溶解于生理盐水，配成浓度为20mg/ml的溶液，与等量完全弗氏佐剂混匀，注入家兔肩胛区皮下致敏，每只家兔每次注射1ml，于肩胛区5个不同区域注射，每周一次，连续注射3周而致敏，第4周向膝关节腔注射卵蛋白生理盐水溶液，每只关节腔注射5mg卵蛋白，15只家兔膝关节全部注射，24h内此关节直径和表面温度大幅度上升，以后缓慢下降，至14～21d达到平台期，发病率达100%。造模成功后第1～4周为早期改变，第4周以后出现不可逆的关节软骨及骨破坏。采用高频超声对RA模型组与对照组的膝关节髌上囊液体厚度、滑膜及股骨髁软骨厚度及软骨下骨皮质的回声情况进行对比观察。结果RA组模型组膝关节髌上囊积液及滑膜的厚度明显厚于对照组，其股骨髁软骨的厚度与对照组相比无明显差异，其软骨下骨皮质与对照组相比无明显改变。

So-called anatomical stems hae a slight proximal posterior bow to reproduce the contour of the femoral endosteum, thereby predetermining the rotational alignment of the implant.

所谓的解剖型股骨柄近端有一略微向后的弓形，以重现股骨内部的轮廓，从而预先固定了假体的旋转方向。

Ensuring the femoral epicondyle axes by the preoperative CT scan is an effective way to determine the femoral prothesis rotational angle.

术前CT扫描确定股骨远端后髁角可以有效提高TKA手术股骨假体旋转力线，方法简单、有效、重复性良好。

The distance from medial sulcus to the distal joint line is 25.7 mm, the distance from lateral epicondyle to the distal joint line is 24.6 mm. The distance from medial sulcus to the posterior joint line is 29.1 mm, the distance from lateral epicondyle to the posterior joint line is 23.6 mm.

各参考点到关节面的距离也与西方人不同，股骨内髁凹穴、外上髁到远端关节面的距离分别是25.7 mm、24.6 mm ；股骨内髁凹穴、外上髁到后侧关节面的距离分别是29.1 mm、 23.6 mm。

The size of the epicondyles in Chinese is significantly smaller than that of the Westerns. The ratio between anterior posterior width of the medial epicondyle and the width of the STEA is 0.84, and is 0.87 between anterior posterior width of the lateral epicondyle and the width of the STEA. The distance from the epicondyles to the joint line is helpful to locate the STEA. The reliability is poor to locate the STEA by touch or PCL.

国人股骨远端上髁解剖大小明显小于欧美国家人群，股骨远端内外上髁的前后径与STEA宽度成一定比例，STEA的骨性标志与膝关节后侧及远端关节线的距离可为定位STEA提供一定帮助，通过术中触摸或PCL定位STEA的可靠性差。

During an aerage follow-up period of 5.1 years, only two supracondylar femoral fractures occurred, both in femora treated without notching.

在随后平均5.1年的随访，连同股骨没有开槽的，只有2例股骨髁上骨折发生。

We will see more and more activist government policies that distinguish economic activities according to the nationality of the actors.

我们将看到越来越多激进的政府政策，这些政策根据企业的国籍来区分经济活动。

If we can prove the independence of an axiomatic system, then we can guarantee the conciseness of this system, ie.

如果能够证明某个一阶谓词系统的独立性，那么就能够保证该系统的建立是精炼的，即没有任何一条公理或推理规则是多余的。
